Interface Space.Listener

  • Enclosing class:
    Space
    public static interface Space.Listener
    The Listener interface is the way applications receive information about events occurring in a Space. Implementations of this interface must be bound to variables that applications keep track of as they are kept as WeakReferences. (This is to defend against keeping a Space active in the event of an Activity crash).

    Listeners start receiving events after join, and will cease after they have left. If a Space is already active and another listener joins then both listeners will receive events, but the new listener will also receive events sufficient to recreate the state of the Space. This is to make user interface development easier.

    All these callbacks into the application occur on the UI thread. The SDK is multithreaded and all calls into it should be safe as we handle the threading for you.

        This does not mean we start receiving media for it, just that someone else is publishing. To receive the media you must also be subscribed.

        Right now we auto-subscribe to all added tracks, so this will be shortly followed by onParticipantTrackSubscribed.
        Parameters:
        space - The Space this callback applies to
        participant -
        track -

        Called when a participant has unpublished a track
        Parameters:
        space - The Space this callback applies to
        participant -
        track -

                                          Track track)
        Called when we have successfully subscribed to a track.

        This means media should be streaming to the track. If it's audio it will play automatically, for video you will need to attach the Track to an appropriate view such as a TrackRendererSurfaceView.
        Parameters:
        space - The Space this callback applies to
        participant -
        track -

                                            Track track)
        Called when we have been unsubscribed from a track.

        This means media is no longer available for this track.
        Parameters:

        space - The Space this callback applies to
        participant -
        track -

      • onParticipantTrackUnmuted

                              java.util.Set<java.lang.String> activeSpeakerParticipantIds)
        Called when the set of active speakers has changed

        This is useful for features such as highlighting the speaker in a video call application. The provided Set is single use and you will receive all new Set instances with each update.
        Parameters:
        space - The Space this callback applies to
        activeSpeakerParticipantIds -

      • onBroadcastStateChanged

        default void onBroadcastStateChanged​(Space space,
                                     Space.BroadcastState broadcastState)
        Called when the Space BroadcastState has changed.

        This is useful for features such as showing a recording indicator in a video call application.
        Parameters:
        space - The Space this callback applies to
        broadcastState -

      • onError

        default void onError​(Space space,
                     MuxError error)
        Called when an error in the Space occurs.

        Note that this isn't limited to Space.Errors but also LocalParticipant.Errors etc. If it happened in the Space it'll land here.
        Parameters:
        space - The Space this callback applies to
        error - The MuxError

      • onMuxSpacesConnectionStateChanged

        default void onMuxSpacesConnectionStateChanged​(Space space,

        Called when the connection state changes.

        You shouldn't need to handle this. However, if a Space becomes disconnected for now the best thing to do is leave and re-enter. This is likely to change.
        Parameters:
        space - The Space this callback applies to
        state -
