Version 12.0.10 - 2024-07-24

Added cache in front of Google Time Zone API.
Improved project setup to support building in Visual Studio Code.

Version 12.0.9 - 2024-06-18

Prevented automatic TLS certification for domains with more than 4 parts. This prevents a recursive subdomain problem when DNS includes wildcard.

Version 12.0.8 - 2024-06-06

User navigation disabled when the require two factor cloud configuration option is enabled and the user has not yet set up two factor.
Sign out button added to the setup 2 factor dialog.

Fixed unhandled exception when manually adding a screen that had never connected to a server.

Version 12.0.4 - 2024-04-11

Added new cloud configuration option to require users to set up two factor authentication. This option will prevent users disabling two factor authentication. Users without two factor set up will be prompted to do so when they sign in.
Added new condition builder to simplify targeting specific screens.
The screenId field is now automatically added to screen data. It can not be changed. This simplifies using screen ID in conditions.
Fixed a problem performing some SAML authentication operations.

Version 12.0.3 - 2024-03-04

Fixed issue that could prevent remote RSS feeds from being updated.
Players built after this date will not send direct proof of play if a configured dpopCondition contains an error.

Version 12.0.2 - 2024-03-01

Resolved logging and monitoring issue that failed to acknowledge RSS update completion.

Version 12.0.1 - 2024-02-25

Modified default selected software for newly connected Android devices to be SignageNode.

Version 12.0.0 - 2024-02-07

Updated all Java archive dependencies used by server platform.
Updated ACME implementation (certificate automation) to match API changes.
Reduced server start time to under 1 second by optimising Morphia startup process.
Reduced processing overhead when many screens request the same RSS while cache is being primed.
Fixed issue preventing sequence item editor copying libraryItemId from a library item into sequence item. This fix also ensures stars are removed from a library item when added to a sequence.

Version 11.3.0 - 2024-01-27

Updated admin interface to use GWT 2.11.0 (release 2024-01-09).
Significantly improved efficiency of Media RSS feed updating.
1. Sequence only updated if an RSS change will affect playback. (Ignores metadata such as TTL)
2. Note: The value of rssMd5 is no longer the binary MD5 of the RSS response, it is a composite of RSS display data.
3. Added support for rssExpirationOffset in sequence data to offset when an RSS feed will be updated. (Useful when aligned with clock multiple of TTL or adding additional delay)
4. The value of rssExpirationMillis in sequence data is now unused. Expiration will now be managed in server RSS caches. This avoids updating a sequence when expiration changes after an update.
5. Background update of an RSS feed updates media datasources before updating cache entry. This avoids pending resources during a sequence update.

Version 11.2.0 - 2024-01-20

When sequence item display counts are incremented, replication data merge takes longer and can introduce a race condition if a screen communicates during the data merge period. The following changes help resolve this issue:
1. Modified server to server data replication to only update screen data fields that have changed during merge (not the entire screen object). This change compliments the field level screen updates introduced in version 11.1.0. A concurrent modification of the same field during the data replication merge is very unlikely.
2. Increased the replication rate. A 500ms delay is used between repeat replication communications.
3. Decreased the max objects transferred during replication communications to 2000. Smaller batches means lower data merge latency.
Additional locking added to ensure only one RSS feed update for a given URL occurs concurrently when RSS cache is empty (startup).
RSS feed expiration is now aligned with a clock multiple of TTL (when TTL set in RSS XML). This coalesces multiple RSS feed updates into a single screen update when multiple RSS feeds are referenced.
Avoids unnecessary data source update when a new cloud config is used but no custom blobstore is defined in the cloud config.

Version 11.1.8 - 2024-01-01

Removed SignageNode players with build date before 2023-06-17 that contained expiration of 2024-01-01.
Removed older players to encourage updating to more recent players.

Version 11.1.7 - 2023-12-18

Fixed issue where duplicate sequence IDs could appear in library item.

Version 11.1.7 - 2023-12-17

Sequences populated by RSS will no longer be updated if the MD5 of the RSS response body does not change. Workaround for broken revalidation on remote server (IBM).

Version 11.1.6 - 2023-12-16

Automatically reset SignageNode warnings in admin interface when reverting to standard player.
Marked itemId, libraryItemId and userId in admin interface data as read only.
Fixed problem preventing loader communications using a server address that does not match a stored server/cloud configuration.

Version 11.1.5 - 2023-11-25

Fixed problem preventing saving access controls as signed in user while masquerading.

Version 11.1.4 - 2023-11-24

Made it easier to increase max results without changing user settings. The dialog shown by clicking the pagination explanation button (!) now includes a button to refresh with limit of 10,000.
Manually created screens that have never communicated are now shown without requiring extended offline filter to be enabled.
Added a button to screen data tab to quickly jump to using the Quick Data API.
Removed quick access Roku buttons as this functionality is deprecated.

Version 11.1.3 - 2023-11-19

Events tab is now disabled by default for new users. Events will only be supported by older players.
Fixed some issues with dragging components when creating a composite item displaying multiple inner items.

Version 11.1.2 - 2023-11-16

Additional logging for replicating screen data with same operation action time.
When a screen is updated at the same millisecond on multiple servers, the user modification time dictates the data to be saved during replication.
Operations on large numbers of screens (over 20) will not send instant update requests to screens. Regular periodic player comms will be used.
Instant screen update requests intentionally delayed. Repeat requests reset delay count down. This coalesces unnecessary instant update requests during multiple quick update operations.
Added support for valid and condition into RSS items. This enables a remote RSS Feed to set date ranges and conditions for items that will be processed by the player (even when offline).
Improved RSS namespace processing to support multiple namespaces with no strict validation.
Added support for custom loaderCommsPeriod and playerCommsPeriod into cloud configuration data.

Version 11.1.1 - 2023-11-13

Fixed problem preventing persistence of sequenceId when updating screens using Quick Data API.

Version 11.1.0 - 2023-11-11

Loader communications and player communications now perform atomic field level updates instead of object level load and store. Atomic field updates avoid a rare race condition that could occur if screen data is updated at the same time as loader or screen communications.
Quick Data API for screen data updates uses atomic field level updates.
Quick Data API for updating large groups of screens rewritten to significantly improve performance.
Instant screen (UDP) update disabled when more than 100 screens are updated via Quick Data API. Updates will occur during periodic screen communications.
A single blob upload failure to cloud storage in 60 seconds no longer triggers server health check alert. Retries are automatic so threshold increased to 3.
Improved readability of Google map markers and changed marker for moving screens to read GPS and pin to black.
Added support for configuring ads.txt in the cloud configuration.
Added beta support for security.txt and robots.txt.
Fixed Java Servlet processing bug that caused Transfer-Encoding: chunked header to be added to (empty) 304 responses.

Version 11.0.5 - 2023-11-05

Increased performance of Quick Data API screen group updates.
Fixed rendering problem preventing preview player displaying composite library items in admin interface.
Schedule sequence type no longer marked as (new).

Version 11.0.4 - 2023-10-30

Suppressed condition warnings/errors in server log output.
Added LED option to screen editor to set widthOverride and heightOverride values for LED controllers.

Version 11.0.3 - 2023-10-27

Added group label to subject line of screen status notification emails.

Version 11.0.2 - 2023-10-24

Fixed problem processing time based conditions used in sequence export (RSS, Roku and VAST).
Added strict requirement for time to be defined when using evaluation engine.

Version 11.0.1 - 2023-10-23

Fixed problem with filters in API requests when time was not defined.
Synchronized stacks engine evaluation to ensure state in concurrent API requests is not corrupted.

Version 11.0.0 - 2023-10-19

Core stacks condition evaluation engine rewritten.
- Performance of traversing inner sequences significantly improved for complex sequence hierarchies.
- Improved processing outer item durations for inner sequence rotation.
- Selective logging for silent lookahead. Reduces log pollution when conditions have undefined variables. Used by SignageNode for precaching.
- New functions to help with undefined variables in item conditions. These functions are useful when you need to use data in a condition that is not defined in the item, sequence or screen.
  - isDefined("name") Returns true if the data with the given name exists and can be used in condition evaluation.
  - isNullOrEmpty("name") Returns true if the data is not defined, is null or is empty.
  These functions make it possible to bypass errors caused by undefined variables using short circuit evaluation. For example isNullOrEmpty("airportCode") || !stringContains("ATL", airportCode) Remember to quote the name when using these functions!
- Multiple VAST sequences can now be stacked and work as alternatives. An alternative will be used if the item above fails or does not return an advert.
- Players released after 2023-10-11 use this core stacks engine update.
Fixed problem where reencoding an item immediately after upload could fail with ResourceNotFoundException.

Version 10.3.7 - 2023-10-02

Fixed user access escalation option when masquerading as a user that is not permitted to access an item. Failed actions can be repeated as user that signed in prior to masquerade.
Fixed race condition in cache that could lead to NullPointerException if an entry is concurrently accessed and removed.
Removed Twitter from default content builder list. Unfortunately Twitter / X is now hostile to external API integrations and can not be supported.

Version 10.3.6 - 2023-09-20

Fixed problem where the soft links to sequences in library items could be added to sequence stack items. (sequenceId_ prefix)
Screen optimisation stage now strips out (sequenceId_ prefix) from sequence stack items which is not needed by player.
Removed data shared stats from home summary panel and group summary panel. This data is no longer accurate due to changes between standard player and SignageNode.

Version 10.3.5 - 2023-08-30

Fixed problem removing starred items in library side panel when item dragged into sequence.
Improved cache management of icon panel HTML under items.

Version 10.3.4 - 2023-08-21

Fixed problem preventing some access controls from being removed.
Revoking all access controls from a screen now removes player software and sequence configuration to reset it. This allows the screen to become accessible again via MAC to be reused.
Prevented entities internal lists from exceeding 100 records (internal lists end with _#).
Improved error handling by null safe exceptions and retries in admin interface.

Version 10.3.3 - 2023-07-22

Added filter parameter to conditionally update specific screens in a group using Quick Data API. E.g. /api/group-screen-data/[GROUP-NAME]?filter=...

Version 10.3.2 - 2023-06-29

Added auto-correction logic to prevent common typo of name in value. e.g. layer1=layer1=https://...

Version 10.3.1 - 2023-06-09

Fixed problem selecting multiple media items from side panel.
Improved performance of sequence panel cleanup.

Version 10.3.0 - 2023-06-02

Expandable sequence library added to right hand panel of sequences page.
- Toggle between media library and sequence library.
- Sequences from sequence library can be dragged into a sequence to quickly add an inner sequence to a sequence.
- Sequences from sequence library can be dragged into an item of a schedule sequence to change the sequence played during the scheduled time block.
The group select drop down within search/filter panel caused a drop in responsiveness when attached to the DOM (webkit bug?). To keep keep user input responsive, the group select can now be shown and hidden by the group button besides the search button.
Column select drop down now shown and hidden by a new columns button next to group button to keep functionality consistent with group select.
New option to Find screens added to sequence options. This option will transfer the user to the screens tab and show all screens the sequence is displayed on.
Improved handling of inner sequence cyclic loop detection for sequence previews.
Server replication delay now takes into account non direct replication via an intermediate server. This reduces the health check failures when a single link is slow and data can arrive via another server in the replication group.

Version 10.2.4 - 2023-05-20

Removed downloading slice from screen summary pie chart. This is no longer relevant because SignageNode streams through caches for instant playback. This differs from older players which download fully before playback.
Removed Shared data values from screen status history transfer chart. Only older players report how much they upload via peer to peer. SignageNode streams through local caching proxies and this is only measured locally. (Connect to SignageNode to see transfer report).
Downloaded and shared data values merged to give a single value for Internet downloads. This is calculated by subtracting shared from downloaded for data from older players.
Improved integration with Zencoder and Transloadit video encoding services with better error handling.
Updated Transloadit API to use ffmpeg_stack v5.0.0.
Fixed problem processing the same video BLOB by multiple encoders at the same time.
Added advanced video re-encoding presets for H265/HEVC and VP9 and updated configurable defaults.
Preview player in admin interface now runs stacks engine for 10 loops to help test inner sequence rotation.
Removed warning for H.265 mp4 files since 99% of Android devices support H.265 now.
Added warning to preview player when attempting to play H.265/HEVC video. Since web browser support is still poor.
Added green video media file icon when H.265/HEVC is used by video resource.
Added yellow video media file icon when there are video related warnings such as high bit rate.
Reduced server to server replication to a single thread to reduce overlapping updates which wasted bandwidth.

Version 10.2.3 - 2023-04-29

Added new alert button to screens tab. The alert button makes it easier to apply and remove a temporary sequence override which is commonly used for emergency alerts. Button can be hidden by showScreenAlertButton=false in cloud or user data.
Added sequence override selection to screen editor.
Added cloud option to disable sign-in with password. Useful to force signing in with SAML, Google or Microsoft.
Added server option to enter lock down. Regular users will be signed out and blocked from signing in while in lock down. Used by system administrators in attack mitigation.
Added ability to display a server message to users when in lock down.
Improved button layout used on sign-in welcome screen.
Added additional caching layer for item lists used for selecting sequences, groups and users.
Sped up animations to make admin interface more responsive on older devices.
Forcefully removed browser auto-complete in MAC address field because Chrome is ignoring autocomplete=false.
Fixed problem storing previous service health-check events.
Added more health check information for database create, update and delete rates and data warehouse insert rate.
Improved HTTP connection keep-alive logic to close connections early when it is likely they will not be reused.
Increased the maximum number of concurrently handled connections to 500.
When max concurrent connections reached, keep-alive of active connections reduced to 500ms.

Version 10.2.2 - 2023-04-16

Updated automatic domain certificate renewal 30 days prior to certificate expiry as recommended by letsencrypt.

Fixed problem in data warehouse loading chunks created between 2023-03-23 and 2023-04-10.
TLS/SSL certificates are now renewed 30 days before they expire asynchronously when secure domain accessed.

Version 10.1.8 - 2023-04-03

Google introduced GWT incompatibility in corechart version 52. This broke pie charts in admin interface. Google corechart is now frozen at version 51. https://developers.google.com/chart/interactive/docs/release_notes#current:-april-2023

Version 10.1.7 - 2023-03-26

Fixed problem hindering searching for users by email and groups by name.
Suppressed error when operator data can not be saved (which is always the case when adminReadOnly=true)

Version 10.1.6 - 2023-03-24

Added selection clear after library refresh to be consistent with behaviour on other tabs and ensure selected item data is refreshed.
Improved certificate and private key sharing between servers after ACME process completes.

Version 10.1.5 - 2023-03-20

Added support to preview audio only items in admin interface. (requires initial click to unmute, as with video preview)

Version 10.1.4 - 2023-03-17

Fixed problem where empty/null values in API requests were failing to remove data from objects.

Version 10.1.3 - 2023-03-16

Fixed problem generating web page thumbnails when web address contained some query parameters.

Version 10.1.2 - 2023-03-14

Added SAML 2.0 to welcome page buttons when enabled.

Added unified server logging to Google Cloud Logging.
Added unified server monitoring to Google Cloud Monitoring.
Added new health check for recent active user counts.
Improved tracking and monitoring of authentication failures.

Version 10.0.2 - 2023-02-24

Table column presets for small, medium and large screens.
Custom column presets 1-4 can be applied in search panel and modified by users.
Loading large tables of data is faster because scan for custom item data is no longer necessary when only showing default columns.
Fixed issue where uppercase characters in base64 encoded email caused authentication failure for API communications.
Uploads that refer to remote data source now tagged with signed in user rather than remote datasource address to aid searching user action report.
A user with reporting disabled now has access to stack item campaign tab, but can not enable reporting on the item.
Changed logic for updating screens if operator has no access. Previously this was possible if zero USER access controls were associated with screen (i.e. is new screen). This meant that if only group access controls were associated with a screen, it was possible for a user to gain access to a screen if they knew the MAC. This has been changed so that a screen can only be updated by an operator with no access if no player software has been configured.
Changing the columns updates contents of dynamic cells that may need reloading.

Version 10.0.1 - 2023-02-10

Improved rendering of sequence and composite thumbnail for high DPI screens.
Added special thumbnail for Ad Server populated inner sequences.
Added special thumbnail for custom resource items.

Version 9.9.10 - 2023-02-04

Enhanced replication to more efficiently catch up after prolonged offline period.

Version 9.9.9 - 2022-12-21

When a group is specified in cloud config, new screens and new users are added to that group AND groups that have access to that group. (2 levels) This is so that large partners can still access new users and screens if they are assigned to a child group and the user has group recursion disabled.
Added group ID and group name as search tokens for group selection search in search panel.

Version 9.9.8 - 2022-12-18

Added select all and deselect all buttons to multiple group search drop down.
After a server search (enter button), widening a search (via backspace or delete) performs server search again to show full results.
Modified behaviour of the max results limit exceeded button to show popup once or on mouse hover. Click no longer goes to user settings as it caused confusion and too many users increasing limits.

Version 9.9.7 - 2022-12-13

Additional user setting to restrict group access control processing. (performance enhancement for many groups in a master group)
- accessControlProcessing=disableGroups - Only show items the user has direct access to.
- accessControlProcessing=disableGroupRecursion - Only show items the user has direct access to and items within groups the user has direct access to.

Version 7.6.9 - 2019-10-05

Fixed problem selecting a screen/sequence for the playback simulator when over 10,000 screens/sequences.
Inner sequences containing inner sequences introduced a premature MaxDurationExceededException when items referring to the inner sequences did not have durations exceeding the total duration of items referring to the inner sequences at the deeper level. The result was inner sequence rotation applied incorrectly and valid items skipped in the deeply nested inner sequence. If deeply nested inner sequences are in use, please update players to android-player-21.2 and android-exoplayer-8.2. Alternatively, items referring to inner sequences can be configured to have a duration longer than the total duration of the inner sequence items to prevent the issue occurring.
Static random value reset after an item is displayed if data reused.
Fixed problem detecting and propagating sequence frame updates to players.
Updated gwtbootstrap3 to version 1.0.0 and gwtbootstrap3-extras to version 1.0.0.

Automatic Advert Assignment (A3) updated:
- Video advert support added.
- Slot duration restrictions applied to videos.
- Activation e-mails.
- Support for enabling / disabling adverts using authorised link in activation e-mail.
- Advert pools. Uploaded adverts create additional slots. Designed to be used as an inner sequence, where a single advert is shown each loop of the main sequence. This allows displaying more adverts than slots in the main sequence.
New sequence type for Advert pools. This sequence type grants A3 permission to add items.
Assigning a customId that is already used in a sequence no longer merges items to use the same itemId for reporting. This means a customId functions more like a tag where reporting on a customId can return multiple unique items. Logic for RSS sequences differs because the RSS GUID is used as a unique identifier and is used to prevent creating different reporting items when RSS feeds update.
Added support for additionalReadOnlyData in cloud configuration to mark custom data fields as read-only. For example additionalReadOnlyData=LicenceID in active cloud configuration would prevent users changing the LicenceID field in item data.

Version 7.5.3 - 2019-06-28

Version 7.2.5 - 2019-02-01

Fixed error in User and Group summary report for active screen count.
Removed APK link from sign in page for all clouds. Google marked one domain as "unsafe" and it is assumed this is the reason.
Added option to disable group recursion. By default, group recursion automatically lists items contained in nested groups. Adding groupRecursion=false to user data will disable group recursion and limit the visible depth to the first layer of access controls. I.e. Items the user has direct access to and items contained within groups the user have direct access to.

Version 7.2.4 - 2019-01-30

Fixed screen status history report CSV where date/time ranges were shifted back by 1 record.
Abstracted clickable items in tables to use bootstrap badges for simplicity and efficiency.

Server side filtering now uses visible columns for non custom search parameters.

Version 6.4.12 - 2018-08-20

Added upload and import limit of 4GB. This limitation is needed because:
- Android secondary partition, SD cards and USB mass storage using FAT can not store files larger than 4GB.
- Google Cloud Storage does not support uploading over 5GB in a single transfer.
Fixed exception when filtering report by both a user and a group simultaneously.

Version 6.4.11 - 2018-08-16

Fixed minor layout issue showing access control tab on small mobile devices.

Fixed search box that sometimes returned the wrong results when search delayed.
Added condition length limit of 8K. Exceeding limit will show error in admin interface. New players will evaluate these conditions to false.

Version 6.4.8 - 2018-07-24

Fixed problem with data editor ignoring updates to data after it is removed. One known consequence was default duration (60 minutes) lost when selecting a new inner sequence for an item.
Clicking anywhere on the video playback preview will now unmute audio. Please note: videos start muted so autoplay will function (recent Google Chrome policy change breaks autoplay with audio).
Unified the item duration logic. durationMillis not set if it matches a resource duration or the default (10 seconds).
Fixed number formatting problem when resource or item millisecond less than 100.

Version 6.4.7 - 2018-07-19

Label of composite item updated if a new library item is selected.
Updated legacy content builders to use UTF8. Unfortunately many APIs we use only support English terms though.
Added workaround to enable auto-playing videos in HTML5 preview (recent versions of Chrome prevent this). The workaround is to mute the video by default.

Version 6.4.3 - 2018-06-28

Fixed problem searching for meta data by email, group name or cloud config name. This caused problems manually adding new access controls.
Improved validation of display report records sent from players.

- Fixed problem where aggregated records were incorrectly offset by 10 minutes. (Note historical records will show this discrepancy)
- CSV download option (and API response) returns a more understandable format with start and end times for each time period.
Large report queries that exceed number of records that can be displayed in admin interface interrupted to avoid wasting resources. Default limit currently set at 100,000 records.
Record queues are now persisted to local storage, so an unexpected server failure will not result in losing queued records in RAM.
Atomic record queue re-processing to cope with communication failures between servers.
Data warehouse version 2 uses LZ4 compression for archiving instead of GZIP to significantly speed up record processing.
New records and report communications between servers chunked and compressed using LZ4.

Replication rate between geographically distant servers reduced to once every 5 seconds.

Version 5.5.0 - 2018-02-16

Display report and summary report now include the Item ID column.

- When saving a sequence in admin interface, playback reporting option on existing items referring to inner sequences is automatically disabled.
- Screen communications now removes reporting option on items referring to inner sequences.
Display reports and summaries are now processed to remove invalid and duplicate records. An invalid record has an unexpected time, a missing itemId or screenId. A duplicate record has the same display time, itemId and screenId as a previous record.
Increased the max display report size shown in admin interface from 10,000 to 100,000 records.
Automated Advert Assignment (A3) Prototype 1
- Added item scheduling table.

- Schedule advert button adds item to sequence stacks with defined schedule.

Version 5.4.2 - 2018-01-25

The seqeunceId field in legacy database for display reports and collected data reports is no longer used. The itemId is now used to look up the ItemInfo metadata which includes the sequenceId. This results in more compact storage in the legacy database and more consistent results when comparing data with the new data warehouse. Note, if an itemId is duplicated across multiple sequences then the wrong sequence may be referenced. This regresses change made in 5.3.0.
Removed unused field sequenceId from StackItem.
Any sequenceId sent from players in display reports is ignored and new players will not send it.
Default reporting backend when not specified in API request is now the data warehouse.

A3 can now display the available time slots and reserve them (basic scheduling).
Importing media using URLs longer than 1024 bytes is now possible. When a URL is longer than 512 bytes the SHA 256 hash of the URL is used as the primary key for the DataSource object. The full URL is stored in a new data field fullId and automatically reapplied when the DataSource is saved or accessed via DataSourceDao. This fixes the MongoDB 1024 byte key length limitation.

Version 5.3.1 - 2017-12-31

Updated the display tab for items to improve access to various upload, import and building options.
Added new option to build HTML content from template.

Changed default sort order for the screen status history report to use the updated ON column sorting.
Removed option to edit screens from screen status history reports. Reports should not be able to perform updates.
Changed default max duration for items referring to inner sequences to 1 hour - Most users want inner sequences to play more than 10 seconds and inner sequence rotation is often misunderstood, so long default is better.
Fixed group selection problem for reports where group was reset unexpectedly.
Fixed problem where group selection was still visible when an ID was used in reporting criteria. Group filtering is not currently supported when reporting by ID.
Removed unnecessary initial load of screen status history before screens shown in report.
Changed reporting API to use stored sequenceId for legacy reports instead of sequenceId in item metadata. Note, sequence may be wrong in data warehouse if same ID used for multiple sequence items in different sequences.
Subtitle .vtt files modified when uploaded to prevent potential crash. 00:00:00.000 replaced with 00:00:00.001 to avoid divide by zero exception in subtitle renderer on Minix devices.

Storage cleanup triggered when storage used exceeds cleanupThreshold. For example, cleanupThreshold=0.8 performs cleanup when a blobstore location exceeds 80% of the available storage. Cleanup will delete unused, cached BLOBs.
Fixed possible delete and download loop when a blobstore location has inadequate storage available. The measurement for preallocated storage was incorrect, this could lead to blobstore locations marked as inadequate when they met the storage requirements.

Version 7.1 - 2019-06-25

Fixed event duplication problem that subsequently caused double execution of triggered actions.

Version 7.0 - 2019-06-22

Duplicate, matching triggers can now execute multiple actions. Prior to this release, a trigger would only execute the the first action in event list.

Version 4.3 - 2018-08-23

Google Exoplayer library updated to version 2.8.4
When collectGps=true the GPS location is stored periodically on the device. This stored GPS location is then reused following a device restart until an accurate GPS fix is obtained.

Version 4.1 - 2018-08-09

GPS data no longer added to collected data report when collectGps=true is set. This is no longer necessary as the GPS coordinates are added to the display report.
Added requiredGpsAccuracy to support setting the accuracy required for GPS to be updated. Default is 50 meters.
Fixed problem sending display report records when some records contained GPS and some did not. This resulted in sending duplicate entries with the wrong GPS data if no GPS was available when player starts.

Added more logging for player communications.

Version 2.1 - 2018-06-15

Limited gapless playlist to 100 items before reinitialising ExoPlayer component (previously 1000). Long playlists appears to cause stutter sometimes.
Added more logging for NFC detection.

Version 2.0 - 2018-06-06

Downloading prioritises active items and fills storage with scheduled items ordered by start date. This enables using sequences larger than the storage available on the device providing storage is sufficient for active items at any single point in time. Remaining storage is used for as many scheduled items as possible.
When storage is full, the cleanup routine only deletes items necessary to download active items.
Items scheduled later are deleted to make space for items scheduled sooner.
Data sharing via p2p optimised to support larger networks of screens. Peer request list limited to 8 blobs. When localPeerCount exceeds 8, random silencing reduces number of concurrent peer responses.

Version 1.4 - 2018-05-16

Attempts to recover from situation where player start() called twice from DS Loader.
- Double start could result in a duplicate display records.
- When collectGps=true one duplicate record will be missing GPS.

Added additional 5 second delay after download failures to prevent network overload.
Added hdmiState to screen data to report HDMI connection status.

Version 1.1 - 2018-03-02

GPS location stored in display records when collectGps=true added to screen data. Note: when downgrading, previously saved display records containing GPS data will be lost.
Added getScreenData(...) to JavaScript interface.
Added support for sending an RS232 command at startup by adding rs232outputAtStart=... to screen data.

Version 1.0 - 2018-03-02

GPS values now use 5 decimal places in both screen data and collected data. Assuming hardware capable, this is an accuracy of 1.1 meters. Extra decimal places no longer sent to server.
The Android boot time is now added to screen data as hardwareBootMillis. This will allow a app restart to be differentiated from a device restart.
Scrollbars on WebViews now hidden unless resource is marked as interactive.
After 4 months of testing, player has been promoted to version 1.0, stable status.

Version 0.12 - 2018-02-21

After instructing exoplayer to start a video, an extra check is made to verify the video is playing . If the video fails to start, the app will restart.

Version 0.11 - 2018-01-24

Fixed problem where a duplicate report record was generated if an item was inside inner sequences and the item referring to the inner sequence had reporting enabled. This player version will not create the duplicate but will create a report record for the item referring to the inner sequence and items inside the inner sequence as expected.
The sequenceId field in display reports and collected data reports is no longer used. The sequenceId is now derived using the itemId and ItemInfo metadata. This means report storage and sending is more efficient.
Removed unused field sequenceId from StackItem.

Version 0.10 - 2017-11-23

Added support for report=false to screen data. This option will disable reporting entirely.
Prevented reporting on items referring to inner sequences if there are no items ready to be displayed.
When severe problems occur or main thread stalls, the player will auto restart and resume from the next slot. This should ensure the full sequence does get displayed rather than restarting at slot 1.
Modified the download decision logic to prioritise a large blob transfer if none active. This should make better use of bandwidth initially when many small blobs are queued.
Added branch back button
Added default interaction animations

Version 0.9 - 2017-11-15

Fixed restart problem caused by adding inner sequence to a sequence frame.
Added Samsung RS232 Screen control.

Only prints insufficient storage warnings in logs if all storage locations are full.

Version 0.7 - 2017-10-20

Added additional check to confirm video is playing before playback reporting.
Reduced default buffers for ExoPlayer. Only small buffers needed since playback is from local files.

Version 0.6 - 2017-10-17

Added playback reporting.
Added additional logging to monitor playback state changes.

Version 0.5 - 2017-10-12

Added support for showing labels.

Version 0.3 - 2017-09-22

Fixed problem playing short videos less than 5 seconds.
Fixed problem with sequence frame not filling screen if resolution changes while running.
Added playback speed adjustment to more accurately synchronise gapless playback. Strategy:
- 3 seconds before current video due to finish, the predicted end time is compared to desired end time and video speed is adjusted to meet desired end time. This improves the start time accuracy of the next video.

Version 0.3 - 2017-09-22

Fixed problem causing videos with subtitles to stall.
Added support for remote API triggers.

Version 0.2 - 2017-09-20

Please note the availability of this information is dependent on Android version and hardware configuration.
RS232 monitored and text lines added to rs232input in screen data. (Most recently received ASCII line)
Added support for RS232 input triggers to event system.
Added support for regular expression matching to barcode, NFC and RS232 pattern scanning.

Version 21.2 - 2019-10-03

Fixed problem with deeply nested inner sequences skipping items (see server notes 7.6.9).
Fixed problem fetching recently updated screen data using JavaScript interface.

Version 21.1 - 2019-09-13

Fixed problem preventing events added to the screen from firing.

Version 21.0 - 2019-09-04

Local web server added. Enable by adding localWebServerPort=9090
- View and watch live logging information. /log
- View contents of local blobstore and download status. /blobstore/
- Access media in the local blobstore. /blobstore/[blob-id]
- Access current player state. /player-state
DS Loader does not stop running when launching another activity from an event with a resume delay set. DS Loader will return to the foreground after the configured resume delay.
Scrolling text is hidden when blackCondition=true.

Version 20.3 - 2019-08-13

Fixed possible delete and download loop when a blobstore location has inadequate storage available. The measurement for preallocated storage was incorrect, this could lead to blobstore locations marked as inadequate when they met the storage requirements.

Version 20.2 - 2019-08-10

Downloads are saved to the blobstore location with most available storage.
Storage cleanup triggered when storage used exceeds cleanupThreshold. For example, cleanupThreshold=0.8 performs cleanup when a blobstore location exceeds 80% of the available storage. Cleanup will delete unused, cached BLOBs.

Version 20.1 - 2019-06-25

Fixed event duplication problem that subsequently caused double execution of triggered actions.

Version 20.0 - 2019-06-22

Duplicate, matching triggers can now execute multiple actions. Prior to this release, a trigger would only execute the the first action in event list. Please check interactive configurations that use multiple events as this change could have unexpected consequences if there is a reliance on subsequent actions not executing.
Fixed problem displaying single web pages on Android 9 (API level 28) and above. (Caused by disabled MIME type sniffing so pages rendered as text/plain)
Changed default WebView cache to 20 views. (webviewReuse=20)
Changed webview caching behaviour to support redirects from the initial page.
Added F10 key to ask exit.
Data from base sequences added to playback data and accessible via JavaScript interface.

Version 19.3 - 2019-06-19

Local display report file deleted when report=false set in screen data.
New display records with date prior to 2019-01-01 ignored. Assumes system clock failure.
New display records with date prior to lastDisplayRecordMillis ignored.

Version 19.2 - 2019-06-04

Added support for fullscreenWarningText to display full screen warning.

Version 19.1 - 2019-05-31

If counting storage takes over 10 seconds, a storage cleanup is triggered. Cleanup will delete unused, cached BLOBs.
Added support for Uri to extra STREAM intent.

Version 19.0 - 2019-05-28

Invalid BLOB download responses aborted prior to downloading body. (Content-Length header must match expected length)
Stored BLOBs larger than length defined by BLOB ID are deleted.
Duplicate BLOBs found in multiple local blobstores deleted. If BLOBs are incomplete, only largest BLOB is kept.

Version 18.12 - 2019-05-15

Added support for launching custom Android Intents.
Added support for displaying a local camera stream on the screen. To configure, add an item to display streaming media with the address camera://0 or camera://1

Version 18.11 - 2019-05-03

Outbound connections to blobstores and stacks servers now include Referer header set to the cloud config address and User-Agent header set to player version and android version. This will be useful for stats and fault finding.

Version 18.10 - 2019-02-01

Periodic blobstore integrity checking prevented from running at startup unless current time is after corruptionCheckTime and before corruptionCheckTime plus 10 minutes.

Version 18.9 - 2019-01-30

Added last known GPS fix to gpsFixMillis in screen data. This can be used in conditions to confirm GPS is working.
Added additional periodic blobstore integrity checking. This re-checks the data in each BLOB file matches its name (fingerprint) daily. Any file failing verification is deleted (and will be downloaded later). Failure increments blobDataCorruption in screen data. If blobDataCorruption > 0 it is likely file storage on the local device is faulty. Please note, this value will also be incremented if a proxy manipulates downloaded data. Some mobile data providers re-encode images and videos to make them smaller. The player regards this as a Man In The Middle (MITM) attack and will delete the data and increment blobDataCorruption. Default periodic check time is 03:00 (based on screen TimeZone). To change set corruptionCheckTime for example corruptionCheckTime=07:00 to disable, set corruptionCheckTime=disable. Please be aware that is does not affect existing verification checking that occurs immediately after downloads complete.

Version 18.8 - 2019-01-05

The add data action is followed by an automatic refresh of the current slot in sequence. This allows conditions in current slot to be re-evaluated and an alternate item to be selected. Typical use case is to select a different language.
Custom media sources that fail to throw an error or complete within configured duration are now skipped. An additional 20 seconds is added to this timeout to allow for buffering delays.

Version 18.7 - 2018-11-26

Standby black screen option is now always black, overriding any custom background colour that has been set in screen data.

Version 18.6 - 2018-11-14

Fixed problem processing GPS location on devices set to a locale that uses a comma as a decimal separator.

Version 18.5 - 2018-10-08

Added tilde support for passing data through to custom media streaming URLs. For example, the following URL will be updated to replace ~screenId with the screen ID of the active player: http://www.example.com/video?screenId=~screenId.
Added support for receiving data and triggers over the local network. This enables sending GPS location from a separate device on the local network. Contact us for GPS sending APK.

Version 18.4 - 2018-09-12

Fixed problem where the first two storage locations (blobstoreInternal and blobstoreExternal) could still be used even if they are disabled.
The reported values for free storage space are now more accurately updated when custom settings are applied to blobstoreInternal, blobstoreExternal and blobstoreDir.

Version 18.3 - 2018-08-23

When collectGps=true the GPS location is stored periodically on the device. This stored GPS location is then reused following a device restart until an accurate GPS fix is obtained.

Version 18.2 - 2018-08-16

If no GPS location is available when player starts with collectGps=true set, gpsLatitude and gpsLongitude stored in screen data is added to display report records instead.

Version 18.1 - 2018-08-09

GPS data no longer added to collected data report when collectGps=true is set. This is no longer necessary as the GPS coordinates are added to the display report.
Added requiredGpsAccuracy to support setting the accuracy required for GPS to be updated. Default is 50 meters.
Fixed problem sending display report records when some records contained GPS and some did not. This resulted in sending duplicate entries with the wrong GPS data if no GPS was available when player starts.
Enhanced how dynamic clock is set after restarting the app using server time offsets.

Version 18.0 - 2018-07-25

Fixed restart caused by specifying a BLE config when no supported hardware on device.
Added support for displaying HDMI input directly on the screen (pass-through).
- Configured by adding a resource with a streaming media address of hdmi://zidoo.
- Designed and tested for Zidoo X9s (Realtek chipset).
- Please note: Zidoo X9s can not play HDMI IN at the same time as another video. (waiting for new firmware)

Version 17.1 - 2018-07-12

Added support for checking if GPS is inside a polygon for advanced conditions - gpsInside(lat1,lng1,lat1,lng2,lat1,lng2)
Key events are now processed by all sequences currently on the screen.

Version 17.0 - 2018-06-28

Added new screen data option reportOptions=verifyClock to prevent storing reporting records and collecting data if the clock has not be verified as correct.
Built with Gradle 3.1.3 and Android tools 27.0.3

Version 16.2 - 2018-06-28

Updated how display report data and collected data is parsed and sent to the server.
Added more logging for player communications.

Version 16.1 - 2018-06-15

If a custom media resource has a known duration and known duration less than configured item duration the sequence will progress automatically on completion.

Version 16.0 - 2018-06-06

Downloading prioritises active items and fills storage with scheduled items ordered by start date. This enables using sequences larger than the storage available on the device providing storage is sufficient for active items at all points in time. Remaining storage is used for as many scheduled items as possible.
When storage is full, the cleanup routine only deletes items necessary to download active items.
Items scheduled later are deleted to make space for items scheduled sooner.
Data sharing via p2p optimised to support larger networks of screens. Peer request list limited to 8 blobs. When localPeerCount exceeds 8, random silencing reduces number of concurrent peer responses.

Version 15.3 - 2018-05-16

Attempts to recover from situation where player start() called twice from DS Loader.
- Double start could result in a duplicate display records.
- When collectGps=true one duplicate record will be missing GPS.
- Issue more likely to occur on mobile data networks.

Version 15.2 - 2018-05-08

Collected data report corruption issue fixed.

Version 15.1 - 2018-05-03

Added workaround for proxies and firewalls that remove the Range header from requests. Download resuming not possible in such situations.
Added additional 5 second delay after download failures to prevent network overload.
Added hdmiState to screen data to report HDMI connection status.

Version 15.0 - 2018-03-02

GPS location stored in display records when collectGps=true added to screen data. Note: when downgrading, previously saved display records containing GPS data will be lost.
Added getScreenData(...) to JavaScript interface.
Added support for sending an RS232 command at startup when rs232outputAtStart=... added to screen data.

Version 14.5 - 2018-03-02

GPS values now use 5 decimal places in both screen data and collected data. Assuming hardware capable, this is an accuracy of 1.1 meters. Extra decimal places no longer sent to server.
The Android boot time is now added to screen data as hardwareBootMillis. This will allow a app restart to be differentiated from a device restart.
Scrollbars on WebViews now hidden unless resource is marked as interactive.

Version 14.4 - 2018-01-24

Fixed problem where a duplicate report record was generated if an item was inside inner sequences and the item referring to the inner sequence had reporting enabled. This player version will not create the duplicate but will create a report record for the item referring to the inner sequence and items inside the inner sequence as expected.
Removed unused field sequenceId from StackItem.
The sequenceId field in display reports and collected data reports is no longer used. The sequenceId is now derived using the itemId and ItemInfo metadata. This means report storage and sending is more efficient.

Version 14.3 - 2017-12-08

WebView error handling updated.
- Only errors loading the main page are displayed.
- Red error page replaced with more friendly centered message reading No Internet Connection with link to retry.

Version 14.2 - 2017-11-23

Added support for report=false to screen data. This option will disable reporting entirely.
Prevented reporting on items referring to inner sequences if there are no items ready to be displayed.
When severe problems occur or main thread stalls, the player will auto restart and resume from the next slot. This should ensure the full sequence gets displayed rather than restarting at slot 1.
Modified the download decision logic to prioritise a large blob transfer if no large transfers active. This should make better use of bandwidth when many small blobs are queued.
Increased the branch limit from 10 to 100 to support deep interactive menu systems.

Version 14.1 - 2017-11-15

Exit prompt shown when back is pressed 5 times rapidly.
Added Samsung RS232 Screen control.

Version 14.0 - 2017-10-24

Repackaged as APK to support easier testing in Android Studio without DS Loader.
Avoids accessing blobstore as mode public (which was required in early Android for video playback).
Only prints insufficient storage warning in logs if all storage locations are full.

Version 13.2 - 2017-09-08

Player communications timeout increased to 60 seconds.
Single background thread for player communications.

Version 13.1 - 2017-09-01

Fixed problem applying yOverride.

Version 13.0 - 2017-08-17

Bluetooth low energy physical web implementation.
- Screens can now broadcast a beacon that helps connecting to the platform from a nearby device.
- Enable BLE beacon transmission by adding beaconConfig=blepw to screen data. Requires Android 5.1 and hardware support.

Version 12.2 - 2017-08-05

Display report records no longer written if time before the reporting epoc. This happens if the system clock is wrong.

Version 11.14 - 2017-07-15

Support for RS232 HEX encoded output using rs232outputFormat=hex.
RS232 logging improved.

Version 11.13 - 2017-07-06

Output from RS232 after sending command is sent to logcat.
After failing to send a command to RS232, reconnection is attempted.

Version 11.12 - 2017-06-27

The autoStart setting can be applied to screen data. autoStart=false will prevent ds-loader and the player starting after a reboot. The default can also be added to the cloud config and will be complied into ds-loader.apk

Version 11.11 - 2017-06-23

Added new functions for custom timezones in conditions.
Fixed problem that caused unresponsiveness when processing large local display reports for sending. This problem affected devices that connected after collecting data for a week or more offline.

Version 11.10 - 2017-06-03

Empty barcode events ignored and not collected.

Version 11.9 - 2017-05-25

Increased maximum player comms response size from 4MB to 16MB to support more complex sequences. This change is designed to support complex composite items containing 100 or more internal elements.

Version 11.8 - 2017-05-18

Storage statistics sent to server when downloads finish even when updateCondition=false.
Transfer rate statistics are now based on most recent 10 downloads/uploads and not removed.

Version 11.7 - 2017-05-17

Conditional logic for internetBlobsCondition and intranetBlobsCondition now correctly evaluated when updateCondition=false
Default value for internetBlobsCondition and intranetBlobsCondition is updateCondition. This change replaces the 10 minute delay used in android-player-11.6 to detect when updates are disabled.
When active period is too short to download the required data, downloading is controlled by evaluating the conditional logic above.
Frequency of local blob request sending reduced to once every 30 seconds to support slow networks.
Minimum acceptable transfer rate reduced to 4KB/s over a period of 1 minute to support very slow networks without dropping connections.
If a local peer or Internet blob data transfer fails, a retry is not attempted for 5 minutes from same source.
Note: This update will make downloading from secondary Internet blobstores more likely if there are frequent failures.

Version 11.6 - 2017-05-12

Downloads from blobstores are stopped if player communication does not occur for 10 minutes.
- This ensures long running downloads are stopped if the player is not in an active period (i.e. updateCondition is false).

Version 11.5 - 2017-05-04

Composite items containing no resources available no longer prevent composite from being displayed. This is to support invisible touchable regions (or buttons) and avoid the need for invisible PNGs.
Download sources that generated an error are now blocked for 10 minutes. (previously 1 hour).

Version 11.4

Support for stretching images, bypassing aspect ratio lock. (stretch=true in items)

Version 11.3

Player components are reused if onCreate() called twice during screen rotation. Requires DS Loader 12.7.

Version 11.2

Support for RS232 output using USB to RS232 converters.
1. Most Prolific and FTDI chipsets supported.
2. Setup comms by adding data to screen: rs232config=38400,8,1,none (This example will set baud to 38400, bits to 8, stop bits to 1 with no parity)
3. Send output directly from data in an item. For example rs232output=avi=1 (This example will send avi=1 to the serial output)

Version 11.1

Fixed issue that prevented fresh installations creating directories for blobstore in secondary location.

Version 11.0

Peer to peer blob sharing version 2.
- Player periodically broadcasts a blob request list.
- Concurrent blob request processing provides immediate blob response.
- LAN data downloads interrupt active Internet downloads.
- Instant download resuming with nearest byte precision.
- Download queue dynamically updated when sequence changes mid download or a new blobstore added.
- Configurable download and upload concurrency. Defaults: blobDownloadConcurrencyMax=2 blobUploadConcurrencyMax=2
- Configurable min and max transfer rates. Defaults: blobTransferRateMin=10240 blobTransferRateMax=104857600
- Transfer rate data sent to server in data: blobDataDownloadedRate blobDataSharedRate
- Peer to peer v2 uses port 9097 for UDP broadcast.
Blobstore reports storage statistics only when downloading.

Version 10.7

Screen data for restartTime, rebootTime and exitTime transferred to ds-loader.

Version 10.6

Added support for event actions to open 3rd party applications.
Fixed problem introduced in 10.5 that prevented updating the dynamic clock.

Version 10.5

A playback synchronisation request is not sent if a touch action has occurred within last 5 minutes. This means touch actions no longer interfere with other screens timing on a sequence with playback synchronisation enabled.
Status icon added. Enable with showStatusIcon=true.

Version 10.3

A timeZoneOverride in screen data is now set as the system default.

Version 10.2

Fixed issue that interrupted reporting if the user navigated to previous item.

Version 10.1

Fixed issue that could lead to a storage becoming full if two large downloads started concurrently with insufficient free space available for both.

Version 10.0

Uses repackaged classes from server version 4.0.

Version 9.8

Active sequence frames now updated (if required) when downloading completes.

Version 9.7

Bar code scanning can now function even if there are no active items on the screen.

Version 9.5

Fixed problem where videos in a composite failed to start if syncVideoMode=2.

Version 9.4

When playback synchronisation is enabled, video cleanup is delayed by 300ms. Reduces black gaps.

Version 9.3

Barcodes and NFC data now added to screen data even if events not defined so the data can be used in conditions.

Version 9.2

Fixed recursive framing issue that occured if a frame or composite item contained inner sequence.

Version 9.1

Now and Next item information access for HTML sequence frames.
- Sequence offset item lookup added for JavaScript access.
- rootSequence.offset(-1).label returns label of previous item.
- rootSequence.label returns label of current item.
- rootSequence.offset(1).label returns label of next item.
- rootSequence.offset(2).label returns label of item after next.
- Please note that next items are a prediction based on current data used for item evaluation.

Version 9.0

Support for sequence frames added.

Version 8.6

Support for closed captions / subtitles added.
- Ensure captions are enabled in Android settings. (Menu->Settings->Accessibility->Captions)
- Upload .vtt subtitle file to the item in addition to the video. (Check listed as text/vtt after upload)
- For non-english language add the language to the data for the subtitle resource item. For example language=es.
- Android 4.4+ required.

Version 8.5

Support for displaying labels of items in a sequence.
Data from an inner sequence in a composite can now be accessed using JavaScript. For example data named headline from a sequence with the label videos can be accessed using DigitalSignage.getData("videos.headline");

Version 8.4

A thumbnail image with use ticked prevented items displaying on player 8.3. This is now resolved.

Version 8.3

Fixed issue where an inner sequence containing more than one of the same inner sequence reported an error.

Version 8.2

Videos can be started at a specific offset using offsetMillis in item data. offsetMillis must be set to the number of milliseconds from the start of the video. Please note that seek accuracy varies greatly between devices and video types.

Version 8.1

An item will only be selected for display if all resources associated with the item are available.
Resource selection updated to prefer matching aspect ratio images or videos for display area.

Version 8.0

Core evaluation engine updated to handle inner sequences and branching more efficiently.
Fixed problem where a sequence of 10 or more inactive slots could cause subsequent condition evaluation to be skipped.
Data from composite items correctly added to URL when ~dataName is used.

Version 7.6

Fixed issue where two successive triggers in less than the duration of active transition could cause view hierarchy to be cleared.
Added stackNumber to data for use in conditions.

Version 7.5

Text rendering for displaying text items in composites (beta). To be used for rendering RSS title text at the same time as RSS images and videos.

Version 7.4

API Triggers are now routed into active WebViews and call a JavaScript function named DigitalSignageTriggerCallback(data);. This makes it possible to have a direct communication route into a interactive web page running on a device. Ideal for games where a smartphone acts as a controller.

Version 7.3

Fixed bug that could occur if multiple videos are in a single item and the one selected to display has not completed downloading.

Version 7.2

Core stacks engine updated to resolve issues with some advanced conditions.
Video blanker for masking black screen seen between videos with another colour. Set background=#FFFFFF in screen data to enable and videoBlankerPeriod to change the period at the beginning and end of playback to mask.
Additional write check to ensure that read only storage is not included in free-space count.

Version 7.1

Some devices throw a FileNotFoundException when they run out of storage space. This exception now triggers a cleanup. The cleanup will remove all blobs in the blobstore that are not currently in use (reserved).

Version 7.0

Devices that fail to serve valid blobs via p2p blob sharing get blacklisted and subsequently ignored.
WebViews are cached and reused for quick web page display. Disable with webViewReuse=0.
Minimum blob transfer rate controlled using blobTransferRateMin. Connections are terminated if transfer rate falls below this value. Alternate sources will be used.
Maximum blob transfer rate controlled using blobTransferRateMax. Transfer is paused when rate exceeded. Useful for devices that can not download at high transfer rate and play HD videos at the same time.
Transfer rates of blobs added to log output.

Version 6.6

Event actions to show item with a undefined resume delay no longer causes app restart.

Version 6.5

Screen cleared and controller removed when sequence set to none after being active. Resolves issue with blackCondition not functioning.
Device TimeZone can now be overridden by setting timeZoneOverride in screen data.
Overridden values such as xOverride, yOverride, widthOverride, heightOverride must follow convention of Override being a suffix not prefix.

Version 6.4

Multiple video playback synchronisation modes added see manual.

Version 6.3

Event actions to show web page with a undefined resume delay no longer causes app restart.

Version 6.2

Additional playback synchronisation optimisation to improve accuracy.

Version 6.1

Playback synchronisation code rewritten.
- Players maintain an accurate local dynamic clock using server time.
- Items are scheduled based on the local dynamic clock to reduce effects of network latency.
- New settings syncOffset and syncVideoOffset added to make small changes when hardware differs.
- Devices no longer send playback synchronisation data if they are downloading or missing content.
- All local players must be upgraded to version 6+ to use this new algorithm.
- Upgrading DS Loader to version 8.6+ will enhance accuracy of dynamic clock.
When local peers download from a peer still downloading from the Internet, the local data streams are throttled rather than trying again later. This removes the 1 minute retry delay that could cause slow local blob sharing.

Version 5.4

Key sequences (such as from barcode reader) only trigger events in main sequence and not inner sequences within composite views.

Version 5.3

Jackson JSON serialisation library updated to 2.3.2 (last version supporting Android 2.2).

Version 5.2

SurfaceView added to FrameLayout at startup to remove flicker when VideoView added later. See http://stackoverflow.com/questions/8772862/surfaceview-flashes-black-on-load/12636285#12636285 .

Version 5.1

Bitmap cache now uses ActivityManager.getMemoryClass() instead of Runtime.maxMemory() to estimate how much memory to use for caching rendered bitmaps. This improves stability on devices that incorrectly report maximum memory. Can be overridden by setting maxBitmapCacheSize in screen data.
Temp directory now emptied at startup.

Added support to download, extract and execute special update packages. The update.zip must contain a file named update.sh containing shell commands for how to apply the update.
When the option to Launch at startup and keep running is enabled, 2 Android alarms are continuously set to re-launch DS Loader after a failure. If the first launch fails, the 2nd occurs one minute later.
Commands to post logs and screenshot now use a proxy server if configured.
Device identification added to HTTP requests. (screenId in User-Agent and serverAddress in Referrer)

Version 14.6 - 2019-05-08

Reboot command no longer requires root permissions if APK signed with system key.

Version 14.5 - 2019-04-26

Reboot command attempts to use Android power manager to trigger a system reboot. Note, this will only work if the .apk has been signed with system key. If it fails, the standard reboot shell command is used (requires root).

Version 14.4 - 2019-04-07

Some new devices were incorrectly reporting 000000000000 as the MAC. If this occurs, alternate ways of reading the MAC address will be attempted. If they all fail, a random unused MAC starting 0200 will be used.

Version 14.3 - 2019-01-19

Fixed problem with self upgrading. This prevented versions 13.0 and 14.0 from being able to upgrade ds-loader.apk to new versions on some rooted devices. Upgrading DS Loader from these versions must be performed manually.

Version 14.0

Android 9 Pie blocks all web requests without encryption by default. Unfortunately, this prevents displaying clear text web sites, public blobstores and breaks proxy caching. DS Loader 14 enables a network security configuration that sets cleartextTrafficPermitted=true to remove restrictions.

Version 13.0

Fixed bug where DS Loader would start, exit and start again immediately after booting (if boot less than 40 seconds).
- Problem caused by player start notification sent to server before starting completed and without player version populated. The server would instruct ds loader to change player, which required an app restart. Server side fix applied to prevent this bug in 6.2.0.

Version 12.8

Reads autoStart from default.properties. This allows the default autoStart setting to be configured in the cloud config and compiled into the custom APK.

Version 12.7

Prevention of a second instance of a player starting when onCreate() called twice during rotation on some versions of Android.

Version 12.6

Screenshot option now uses Android system screencap on rooted devices so hardware accelerated video can be captured.

Version 12.5

APK rebuilt and versionName set to 12.5 and versionCode to 1205

Version 12.4

New Android Intent added to support USB to RS232 devices.

Version 12.3

Scheduled restart, reboot and exit applied from screen data restartTime, rebootTime and exitTime variables. (Requires player 10.7)

Version 12.2

Issues "netcfg eth0 down, netcfg eth0 up" if device rooted, eth0 is active and no comms in last 10 minutes.

Version 12.0

Now uses repackaged classes from server version 4.0.

Version 11.2

Loader information no longer displayed when running as a daydream.
Hardware product label and Android API version displayed top right.
MAC address shown top left in addition to center to help with reading on screens where the full resolution not visible.

Version 11.1

MAC addresses 525400123456 and 00904C112233 are blacklisted. If a device has either of these MAC address or an address that starts 02 then new random address will be generated and verified with the server to be unique before it is used.

Version 10.2

Network interfaces monitored. A retry will occur sooner after a network interface reports being reconnected.
Connection timeout and read timeout for posting logs and screenshots increased from 10 seconds to 30 seconds.
Connections to post logs and screenshots will retry up to 5 times.
DS Loader information now fades out before player starts.

Version 10.1

Fix for devices that take up to a minute to restart. Life cycle changed so that finish() will cause management loop to exit and not wait for onDestroy().

Version 10.0

Changed logic for automatic WiFi repair. WiFi is now turned off and on (reset) only after 20 successive communication failures. WiFi will not be repaired if it is disabled (alternate connection assumed) unless it was known to be disabled when performing automatic WiFi repair.
Log entries reformatted to highlight starting and finishing the main DS Loader management loop.
New permissions added for supporting future features such as voice commands.
The Android System UI is only killed if the device is known to be rooted.

Version 9.4

Root detection moved off main thread to improve startup time and reduce chances of ANR warning at startup.

Version 9.3

Detection of rooted devices is more reliable. Tests by attempting to write a temporary file to protected area of file system as super user and checking it exists.

Version 9.2

Old v1 players are disabled, then killed then removed. (Device must be rooted)

Version 9.0

Additional layer of security added to verify player update integrity.

Version 8.7

Device TimeZone used by restartTime can now be overridden by timeZoneOverride.

Version 8.6

Server time sent to the player improving dynamic clock accuracy for playback sychronisation.

Version 8.5

MAC address now listed in DS Settings.

Version 8.3

Rooted devices search for and delete v1 players.

Version 8.2

Temp directory (used for testing) now emptied at startup.
