5.0 Changelog: Twilio Video Android

The Twilio Programmable Video SDKs use Semantic Versioning. Twilio supports version N-1 for 12 months after the first GA release of version N. We recommend you upgrade to the latest version as soon as possible to avoid any breaking changes. Version 5.x is the latest Video Android version.

Support for 4.x will cease on October 23rd, 2020. This branch will only receive fixes for critical issues until that date. Check this guide when planning your migration to 5.x.

Support for Android SDK 3.x ended on February 22nd, 2020.

5.8.1 (June 16th, 2020)

Bug Fixes

  • Fixed the issue where unpublishing and then republishing a LocalVideoTrack using VP8 simulcast does not complete.

Maintenance

  • Upgraded to Android Gradle Plugin 4.0.0 and Gradle 6.1.1
  • Upgraded the SDK to use AndroidX. Please follow the Migrating to AndroidX instructions to consume Video Android 5.8.1 in your app.

Known issues

  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

Features

Bandwidth Profile

You can now configure how your available downlink bandwidth will be distributed among your subscribed RemoteVideoTracks by using a new optional ConnectOptions parameter bandwidthProfile. For more details and best practices, visit the Network Bandwidth Profile API guide. Here is a brief example:

Room room = Video.connect(context, new ConnectOptions.Builder(accessToken)
                .bandwidthProfile(new BandwidthProfileOptions(new VideoBandwidthProfileOptions.Builder()
                         // Minimum subscribe priority of Dominant Speaker's RemoteVideoTracks
                        .dominantSpeakerPriority(TrackPriority.HIGH)
                         // Maximum bandwidth (Kbps) to be allocated to subscribed RemoteVideoTracks
                        .maxSubscriptionBitrate(150000L)
                        // Max number of visible RemoteVideoTracks. Other RemoteVideoTracks will be switched off
                        .maxTracks(3)
                        // Subscription mode: COLLABORATION, GRID, PRESENTATION
                        .mode(BandwidthProfileMode.COLLABORATION)
                        .renderDimensions(new HashMap<TrackPriority, VideoDimensions>(){{
                            // Desired render dimensions of RemoteVideoTracks with priority LOW.
                            put(TrackPriority.LOW, VideoDimensions.CIF_VIDEO_DIMENSIONS);

                            // Desired render dimensions of RemoteVideoTracks with priority STANDARD.
                            put(TrackPriority.STANDARD, VideoDimensions.VGA_VIDEO_DIMENSIONS);

                            // Desired render dimensions of RemoteVideoTracks with priority HIGH.
                            put(TrackPriority.HIGH, VideoDimensions.HD_720P_VIDEO_DIMENSIONS);
                        }})
                        // Track Switch Off mode: DETECTED, PREDICTED, DISABLED
                        .trackSwitchOffMode(TrackSwitchOffMode.DETECTED)
                        .build()))
                .build(),
        roomListener);

Track Switch Off

As part of the Bandwidth Profile API, you can now specify the mode to control remote video track switch off behavior. The new TrackSwitchOffMode enum can be specified in the VideoBandwidthProfileOptions class and can be set to one of the following:

  • TrackSwitchOffMode.PREDICTED - In this mode, RemoteVideoTracks are pro-actively switched off when network congestion is predicted by the bandwidth estimation mechanism. This mode is used by default if not specified.
  • TrackSwitchOffMode.DETECTED - In this mode, RemoteVideoTracks are switched off only when network congestion is detected.
  • TrackSwitchOffMode.DISABLED - In this mode, RemoteVideoTracks will not be switched off. Instead tracks will be adjusted to lower quality.

Track switch off events are provided via two additional callbacks to RemoteParticipant.Listener.

RemoteParticipant.Listener remoteParticipantListener = new RemoteParticipant.Listener() {
    ...

    @Override
    public void onVideoTrackSwitchedOff(
        @NonNull RemoteParticipant remoteParticipant,
        @NonNull RemoteVideoTrack remoteVideoTrack) {}

    @Override
    public void onVideoTrackSwitchedOn(
        @NonNull RemoteParticipant remoteParticipant,
        @NonNull RemoteVideoTrack remoteVideoTrack) {}
}

Track Priority

While publishing a local track, you can now optionally specify its publish priority.

/*
 * Publish a local track with high priority
 *
 * In addition, local track publications now contain a priority property which reflect the priority of
 * the published track.
 */
LocalTrackPublicationOptions localTrackPublicationOptions = new LocalTrackPublicationOptions(TrackPriority.HIGH);
localParticipant.publishTrack(localVideoTrack, localTrackPublicationOptions);

/*
 * The publish priority is also represented in remote audio, video, and data track publications.
 */
remoteVideoTrackPublication.getPublishPriority();

Also, the publisher's TrackPriority for the corresponding local Track can be updated after a track has been published.

localVideoTrackPublication.setPriority(TrackPriority.STANDARD);

When a TrackPriority is updated after the track has been published, remote participants will be alerted to the change via the onAudioTrackPublishPriorityChanged(), onVideoTrackPublishPriorityChanged() and onDataTrackPublishPriorityChanged() Listener methods.

Additionally, you can set a subscriber side priority for a RemoteVideoTrack.

/*
 * Set a remote video track priority to HIGH. Note that this feature is only available
 * for RemoteVideoTrack.
 */
remoteVideoTrack.setPriority(TrackPriority.HIGH);

/*
 * Get the current remote video track priority.
 */
TrackPriority remoteVideoTrackPriority = remoteVideoTrack.getPriority();

This signals to the media server the relative importance of the track with respect to other tracks that may be shared to the Room. The media server takes this into account while allocating a subscribing RemoteParticipant's bandwidth to the corresponding remote track. If you do not specify a priority, then it defaults to TrackPriority.STANDARD.

API Updates

  • Added TrackPriority for track priorities of Room.
  • Added a new class LocalTrackPublicationOptions to specify track publication options when publishing tracks via LocalParticipant.
  • Added additional LocalParticipant.publishTrack methods that allow developers to specify LocalTrackPublicationOptions.
  • Added a new TrackPriority property to LocalAudioTrackPublication, LocalVideoTrackPublication, and LocalDataTrackPublication.
  • Added a new read-only property publishPriority of type TrackPriority to RemoteAudioTrackPublication, RemoteVideoTrackPublication, and RemoteDataTrackPublication. These read-only properties fetch the priorities at which the remote Audio, Video, and Data Tracks were published.
  • Added the RemoteParticipant.Listener.onAudioTrackPublishPriorityChanged(), RemoteParticipant.Listener.onVideTrackPublishPriorityChanged() and RemoteParticipant.Listener.onDataTrackPublishPriorityChanged() methods.
  • Changed the annotation of LocalParticipant.getLocalAudioTracks, LocalParticipant.getLocalVideoTracks, and LocalParticipant.getLocalVideoTracks from @Nullable to @NonNull. These methods were incorrectly annotated in a previous release.

Bug Fixes

  • Fixed a crash when the SDK was processing a local SDP that had incorrect number of SSRCs when applying VP8 simulcast.

Known issues

  • Unpublishing and then republishing a LocalVideoTrack using VP8 simulcast does not complete. As a workaround, disable the Track instead.
  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.7.0 (May 29th, 2020)

Enhancements

  • Previously, the Video Android SDK would fail connection attempts if the signaling server was busy with too many requests. Now, it will try again after a server specified backoff period either until it is successfully connected or the server asks it to stop trying. In this case, the onConnectFailure method is called with SIGNALING_SERVER_BUSY_EXCEPTION.
@Override
public void onConnectFailure(@NonNull Room room, @NonNull TwilioException twilioException) {
    if (twilioException.getCode() == TwilioException.SIGNALING_SERVER_BUSY_EXCEPTION) {
        Log.d("RoomListener", "Twilio's signaling server cannot accept connection requests at this time.");
    }
}

API Changes

  • Added error code definitions:
    • SIGNALING_SERVER_BUSY_EXCEPTION
    • ROOM_ACCOUNT_LIMIT_EXCEEDED_EXCEPTION
    • PARTICIPANT_ACCOUNT_LIMIT_EXCEEDED_EXCEPTION
    • PARTICIPANT_INVALID_SUBSCRIBE_RULE_EXCEPTION
    • TRACK_DATA_TRACK_MESSAGE_TOO_LARGE_EXCEPTION
    • TRACK_DATA_TRACK_SEND_BUFFER_FULL_EXCEPTION
    • MEDIA_DATA_TRACK_FAILED_EXCEPTION
    • MEDIA_DTLS_TRANSPORT_FAILED_EXCEPTION
    • MEDIA_ICE_RESTART_NOT_ALLOWED_EXCEPTION

Known issues

  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.6.0 (April 30th, 2020)

Enhancements

  • A subset of Android devices provide an OpenSLES implementation. Although more efficient, the use of OpenSLES occasionally causes echo. As a result, the Video SDK now disables OpenSLES by default unless explicitly enabled. To enable OpenSLES, execute the following before invoking Video.connect(...) : tvi.webrtc.voiceengine.WebRtcAudioManager.setBlacklistDeviceForOpenSLESUsage(false).

Known issues

  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.5.1 (April 24th, 2020)

Bug Fixes

  • Fixed an occasional native crash when disconnecting from a Room.
  • Fixed a bug when establishing a signaling WebSocket that might cause only one address family (IPv4 or IPv6) to be tried.
  • Publish stats reports every 10 seconds and active ICE candidate pair messages every 20 seconds. Previously both were reported every 4 seconds.

Known issues

  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.2.0 (March 9th, 2020)

Features

  • Implemented Network Quality for Remote Participants in Group Rooms:
    • To enable the Network Quality functionality, set the ConnectOptions.Builder.enableNetworkQuality property to true when connecting to a Group Room. By default this enables network quality level changes to be reported for the Local Participant. To also receive network quality level changes for the Remote Participants, a configured NetworkQualityConfiguration object needs to be supplied to the ConnectOptions.Builder.networkQualityConfiguration property.
    • The networkQualityLevel property has been moved from the LocalParticipant class to the Participant interface.
    • To determine the current network quality level for both Local and Remote Participants, query the networkQualityLevel property. Note, this will return NETWORK_QUALITY_LEVEL_UNKNOWN if:
      • The ConnectOptions.networkQualityEnabled property was set to false OR
      • Using a Peer-to-Peer room OR
      • The network quality level has not yet been computed
    • Implementing the onNetworkQualityLevelChanged method on your LocalParticipant.Listener will allow you to receive callbacks when the network quality level changes for the Local Participant.
    • Implementing the onNetworkQualityLevelChanged method on your RemoteParticipant.Listener will allow you to receive callbacks when the network quality level changes for the Remote Participant.
// Enable network quality
NetworkQualityConfiguration configuration =
        new NetworkQualityConfiguration(
                NetworkQualityVerbosity.NETWORK_QUALITY_VERBOSITY_MINIMAL,

5.0.0-beta4 (October 2nd, 2019)

Network Quality API

  • Implemented the Network Quality functionality for Group Rooms:
  • The Network Quality feature is disabled by default, to enable it set the ConnectOptions.Builder.enableNetworkQuality property to true when connecting to a Group Room.
    • To determine the current network quality level for your Local Participant, call LocalParticipant.getNetworkQualityLevel(). Note, this will return NETWORK_QUALITY_LEVEL_UNKNOWN if:
      • The ConnectOptions.networkQualityEnabled property was set to false
      • Using a Peer-to-Peer room
      • The network quality level has not yet been computed
    • Network Quality Level for Remote Participants will be available in a future release
    • Implementing the onNetworkQualityLevelChanged method on your LocalParticipant.Listener will allow you to receive callbacks when the network quality level changes
// Enable network quality
ConnectOptions connectOptions =
                new ConnectOptions.Builder(token)
                        .roomName(roomName)
                        .enableNetworkQuality(true)
                        .build();

// Override onNetworkLevelChanged to observe network quality level changes
LocalParticipant.Listener localParticipantListener = new LocalParticipant.Listener() {
    ...

    @Override
    public void onNetworkQualityLevelChanged(
        @NonNull LocalParticipant localParticipant,
        @NonNull NetworkQualityLevel networkQualityLevel) {}
}

// Connect to room and register listener
Room room = Video.connect(context, connectOptions, roomListener);
LocalParticipant localParticipant = room.getLocalParticipant();
localParticipant.setListener(localParticipantListener);

// Get current network quality
localParticipant.getNetworkQualityLevel();

API Changes

  • When a Participant connects to a Room, the WebSocket handshake is required to complete in 15 seconds or less, otherwise TwilioException.SIGNALING_CONNECTION_ERROR_EXCEPTION is raised.
  • Added LocalParticipant.signalingRegion. You can use this property to determine where your Participant connected to a Room, especially when using the default value of "gll" for ConnectOptions.Builder.region.
  • Added Room.mediaRegion. You can use this property to determine where media is being processed in a Group Room.
  • EncodingParameters now expresses maximum bitrates in Kilobits per second (Kbps) instead of bits per second (bps).
// Before
EncodingParameters encodingParameters = new EncodingParameters(64000, 800000);
// After
EncodingParameters encodingParameters = new EncodingParameters(64, 800);

Enhancements

  • Increased the reliability of LocalDataTrack by monitoring its send buffer. Sending too many messages, or sending single messages larger than 16 KB no longer causes the underlying channel(s) to close. These requests are ignored instead.

Bug Fixes

  • LocalDataTrack should no longer end up in an inconsistent state after attempting to send a message larger than 16 KB.

Known issues

  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.0.0-beta3 (September 17th, 2019)

Dominant Speaker Detection API

The Dominant Speaker Detection API sends events to your application every time the dominant speaker changes. You can use those events to improve the end user's experience by, for example, highlighting which participant is currently talking.

The Dominant Speaker Detection API is only available for Group Rooms. To enable dominant speaker detection, set the ConnectOptions.dominantSpeakerEnabled property to true. Use Room.getDominantSpeaker() to determine the current dominant speaker. Implement Room.Listener.onDominantSpeakerChanged() method to receive callbacks when the dominant speaker changes.

For more information, refer to the API docs and to the dominant speaker tutorial

 ConnectOptions connectOptions =
                new ConnectOptions.Builder(token)
                        .roomName(roomName)
                        .enableDominantSpeaker(true)
                        .build();
Room room = Video.connect(context, connectOptions, roomListener);

@Override
void onDominantSpeakerChanged(
                @NonNull Room room, @Nullable RemoteParticipant remoteParticipant) {
                // Handle dominant speaker change
        }

API Changes

  • Introduced TwilioException.SIGNALING_DNS_RESOLUTION_ERROR_EXCEPTION, which is now raised instead of TwilioException.SIGNALING_CONNECTION_ERROR_EXCEPTION in the following scenarios:
  • The device has misconfigured DNS Server(s) on its active network interface.
  • The region provided in ConnectOptions was invalid.
  • The device lost its Internet connection before the query could complete.

Enhancements

  • Reduced connection times by removing a round trip when:
  • Reconnecting after a signaling connection failure
  • Connecting with ConnectOptions.iceOptions, and overridden Servers
  • Connecting with default ICE servers (us1 only)

Bug Fixes

  • Fixed crash that occurred when rapidly connecting and disconnecting from a room.
  • Fixed updating CameraCapturer.State when error occurs.
  • Setting ConnectOptions.region to an empty or null value results in the default region being used.
  • Fixed a bug where native memory was leaked after disconnecting from a Room.
  • Fixed a bug where network monitoring would continue on closed connections in a Peer-to-Peer Room.

Known issues

  • In rare cases, the SDK might timeout during a TCP handshake and should be more aggressive at establishing a connection.
  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant. Size Report

  • The Participant's signaling connection now conforms to Twilio's TLS & Cipher Suite Policy. Support for TLS versions older than 1.2 has been removed.
  • Adjusted the buffer sizes used for signaling messages to reduce network fragmentation.
  • Setting video::LogModule::kSignaling enables logging of low-level connection events.

Bug Fixes

  • WebSocket errors are handled immediately, rather than waiting for a timeout to occur.
  • Handle rare exceptions when constructing a WebSocket.

Known issues

  • Future 5.0.0-beta releases will reduce the number of round-trips required to connect to a Room.
  • In rare cases, the SDK might timeout during a TCP handshake and should be more aggressive at establishing a connection.
  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.

5.0.0-beta1 (July 16th, 2019)

Improvements

  • The SDK uses a new WebSocket based signaling transport, and communicates with globally available signaling Servers over IPv4 and IPv6 networks.
  • Added a ConnectOptions.region property. By default, the Client will connect to the nearest signaling Server determined by latency based routing. Setting a value other than "gll" bypasses routing and guarantees that signaling traffic will be terminated in the region that you prefer.
  • Participants are considered to be reconnecting within 15 seconds, and are disconnected from a Room after 45 seconds of lost connectivity. #80
  • Added and updated public API nullability annotations.

Bug Fixes

  • Participants can send messages that are larger than 16 KB.
  • The “roomimpl.worker” thread is no longer needed.

Known issues

  • Setting LogModule.SIGNALING does not produce any logging.
  • Future 5.0.0-beta releases will reduce the number of round-trips required to connect to a Room.
  • In rare cases, the SDK might timeout during a TCP handshake and should be more aggressive at establishing a connection.
  • Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. As a result, tracks published after a Room.State.RECONNECTED event might not be subscribed to by a RemoteParticipant.
