aar docs javadocs

• Reduced SDK footprint, resulting in a noticeable decrease in final application size compared to release 4.2.0.

aar docs javadocs

• Fixed stack dump symbolication on Сrashlytics. In order to make the symbolication work, we needed to reconfigure linker which led to increase of SDK footprint by 10%. We are working hard on reducing the SDK size in next releases.

aar docs javadocs

• Improved connection reliability under bad network conditions.
• Fixed unexpected connectivity errors with code 1401: Unable to establish connection to Twilio Sync service.
• Fixed behavior for UpdateAttributes in Message and User, now updating with null value calls listener's onError().
• Improved documentation for Channel Members.

• Increased targetSdkVersion to 28 in preparation for Google SDK policy targeted in August; minSdkVersion remains 21.

aar docs javadocs

• SDK size reduction - it gained over the course of the year, so we sent it to the gym. Native libraries are now repackaged and optimized for size.

aar docs javadocs

• Fixed crash on shutdown

aar docs

• Fixed crash on restoring after disconnected or backgrounded state
• Fixed memory leaks in media upload

aar docs

• Removed previously deprecated Message.getTimeStampAsDate(). Use Message.getDateCreatedAsDate() instead.

• Calling ChatClient.updateToken() may now indicate an error to the listener if the token validation failed.

• Introduced Push Notification Muting, with per-channel user notification preferences.

  • Added Channel.getNotificationLevel() and Channel.setNotificationLevel(NotificationLevel, StatusListener).
  • Added Channel.NotificationLevel enum with values .DEFAULT to receive notifications and .MUTED to suppress them. Upon leaving the channel, the mute setting for this User is reset to .DEFAULT.
  • Added Channel.UpdateReason.NOTIFICATION_LEVEL enum value when notification level changes.
  • NOTE: You need to grant editNotificationLevel permission to the user roles to be able to change this setting. See the Chat Permissions documentation.

• Added new token lifecycle management delegate callbacks which reduce the need for AccessManager integration when only using one Twilio client SDK:

  • ChatClientListener.onTokenAboutToExpire() is called when a token has 3 minutes or less left until expiry and should be refreshed.
  • ChatClientListener.onTokenExpired() is called when a token is already expired and must be refreshed to reconnect to the service.

• New logging level android.log.LogLevel.VERBOSE is now supported. Use this value to generate logs when reporting SDK issues to Twilio. As before, the default log setting is .SILENT, producing no SDK debug output at all.

• Added Member.UpdateReason.ATTRIBUTES enum value. There's currently no way to query member attributes, it will be added in the following SDK version.

• Added logging of android.os.Build.{BOARD,BRAND,DEVICE,DISPLAY,FINGERPRINT,HARDWARE,MANUFACTURER,MODEL,PRODUCT} on ChatClient startup - this data is logged into the local android log only and is helpful in diagnosing problems, please include it when submitting logs in bug reports!

• Added @NonNull annotations to methods in Messages class.

• Overhauled transport and communication layer, significantly improving network traffic overhead and client performance.

• Provided numerous fixes for improving client stability, focusing on runtime and shutdown crashes.

aar docs

• Resolve crash on shutting down on Oreo devices.
• Resolve crash on shutdown after calling getLastMessages().

aar docs

• Deprecated Message.getTimeStampAsDate(), use Message.getDateCreatedAsDate() instead.

• Added Channels.getSubscribedChannelsSortedBy() to obtain a list of subscribed channels sorted based on a few available criteria: Channel.SortCriterion.LAST_MESSAGE, Channel.SortCriterion.FRIENDLY_NAME, Channel.SortCriterion.UNIQUE_NAME.
• Added Channel.getLastMessageDate() and Channel.getLastMessageIndex() to obtain information about last message activity in the channel.
• Added Channel.UpdateReason.LAST_MESSAGE for last channel message change, you can inspect the two above-mentioned properties of the Channel after receiving this update for new values.

• Resolve crash on accessing last messages in the Channel after some patterns of message deletion.
• Fix local reference table overflow when clearing more than 512 objects from cache.

aar docs

• Made disposed object checks non-fatal - they only log an ERROR level message now.

• You must now request at least 1 message from the channel in Messages.getLastMessages() query. It used to be possible to query for 0 messages and receive no results, but not anymore.
• GDPR-compliance by default - uses log level SILENT to not output anything from SDK by default. Switch to higher debug level using ChatClient.setLogLevel() to receive log messages.

This version is a major version bump due to semver. There are a number of incompatible API changes making this bump necessary.

aar docs

These updates have changed the API in a backwards-incompatible manner.

• ChannelListener.onTypingStarted/onTypingEnded methods now include a Channel in which this event has happened in the signature.
• Chat messages that include media content previously returned a placeholder string "Media messages are not supported". This has caused some confusion, so these messages now return null body instead. Be careful to handle this case properly because it may cause NPEs in the your application if you don't.
• Message.getTimeStamp has been renamed Message.getDateCreated for clarity. The returned value has not changed.
• ChatClientListener.onNotification() method for receiving push notifications has been split into 4 separate methods:
  • onNewMessageNotification(String channelSid, String messageSid, long messageIndex)
  • onAddedToChannelNotification(String channelSid)
  • onInvitedToChannelNotification(String channelSid)
  • onRemovedFromChannelNotification(String channelSid) Now the parameters to these methods are more logical - for example there's no messageSid parameter when it is unused. The new messageIndex parameter provides an easier interface if you need to scroll to a message in the channel from push notification.
• Behavior of Channel.join and Members.add/addByIdentity has changed - methods will fail if user is already a member of the channel.
• Previously deprecated methods are now removed:
  • Messages.advanceLastConsumedMessageIndex(), use advanceLastConsumedMessageIndexWithResult() instead.
  • Messages.setLastConsumedMessageIndex(), use setLastConsumedMessageIndexWithResult() instead.
  • Messages.setAllMessagesConsumed(), use setAllMessagesConsumedWithResult() instead.
  • Messages.setNoMessagesConsumed(), use setNoMessagesConsumedWithResult() instead.

• Media queueing support has been added for media messages, to better utilize upload bandwidth.
• Online documentation format has changed to a more usable one (with search).

• CallbackListener for ChatClient.create will be called on the originating thread. Previously it was called from library thread by mistake.
• Android CA store certificates can be used for connections where possible. This means custom company certificates added on devices should now be honored by the SDK. To enable this feature use ChatClient.Properties.Builder's setDeferCertificateTrustToPlatform(boolean) with value true. By default Twilio-pinned certificate bundle will be used.
• ChatClientListener.onChannelAdded() will be called regardless of if the channel's status is known yet or not, it was not called before if channel status was not yet determined.
• Various internal bugfixes.

aar docs

• Unconsumed messages count on joined channels should immediately reflect changes made by new consumption horizon update methods described below.
• Improved documentation.

• Added logging to reflect ChatClient detecting the application transitioning into the background or foreground.
• Improvements to memory utilization.
• Unimplemented Channel.setType() removed from the SDK.
• Added updated consumption horizon methods which return an updated number of unconsumed messages in the listener callback:
  • setLastConsumedMessageIndexWithResult()
  • advanceLastConsumedMessageIndexWithResult()
  • setAllMessagesConsumedWithResult()
  • setNoMessagesConsumedWithResult()

• Deprecated old consumption horizon update methods which did not take a completion listener. Please use the newly added methods which do accept a completion listener above.

  • advanceLastConsumedMessageIndex()
  • setAllMessagesConsumed()
  • setNoMessagesConsumed()
