Chromecast SDK (Android) - is there a way to check whether the media playing on the cast device has finished playing?

Question

Is there an onFinished listener of some sort? Or do we have to compare the current stream position against the duration of the track?

Answer 1

Prem, There is currently no callback to register for such event. One alternative (and-not-so-pretty) approach is the following: on the receiver, listen for "ended" event of the media element and send an event back to the sender through a private channel. Another approach is what you suggested: check position against duration. When SDK graduates to general availability, better and cleaner approaches will be available to accomplish what you want.

Here is solution: You just need to take one more variable mIdleReason.

1) Initialize mIdleReason as

public int mIdleReason=MediaStatus.IDLE_REASON_NONE;

2) Update value at method loadMedia

 public void loadMedia(String url, MediaMetadata movieMetadata, CastSession castSession, boolean autoPlay, long position) {
        if (castSession == null || !castSession.isConnected()) {
            return;
        }
        MediaInfo mediaInfo = new MediaInfo.Builder(url)
                .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
                .setContentType("videos/m3u8")
                .setMetadata(movieMetadata)
                .build();
        mRemoteMediaClient = castSession.getRemoteMediaClient();
        mRemoteMediaClient.addListener(mRemoteMediaClientListener);
        mRemoteMediaClient.load(mediaInfo, autoPlay, position);

        mIdleReason = MediaStatus.IDLE_REASON_NONE;
    }

3) Update value at onStatusUpdate:

 private RemoteMediaClient.Listener mRemoteMediaClientListener = new RemoteMediaClient.Listener() {
            @Override
            public void onStatusUpdated() {
                if (mRemoteMediaClient == null || mediaPlayerListener == null) {
                    return;
                }
                MediaStatus mediaStatus = mRemoteMediaClient.getMediaStatus();

                if (mediaStatus != null) {
                    int playerStatus = mediaStatus.getPlayerState();
                    Log.d("PlayerState", "onStatusUpdated() called, progress= "+mSeekBar.getProgress() +", stream duration= "+ mRemoteMediaClient.getStreamDuration()+" mSeekBar.getProgress() == mRemoteMediaClient.getStreamDuration()="+(mSeekBar.getProgress() == mRemoteMediaClient.getStreamDuration()));
                    Log.d("PlayerState", "onStatusUpdated() called playerStatus="+playerStatus+", idleReason="+mediaStatus.getIdleReason());

 if (playerStatus == MediaStatus.PLAYER_STATE_PLAYING) {
                        mediaPlayerListener.playing();
                        mIdleReason = MediaStatus.IDLE_REASON_FINISHED;
                    } else if (playerStatus == MediaStatus.PLAYER_STATE_BUFFERING) {
                        mediaPlayerListener.buffering();
                        mIdleReason = MediaStatus.IDLE_REASON_FINISHED;
                    } else if (playerStatus == MediaStatus.PLAYER_STATE_PAUSED) {
                        mediaPlayerListener.paused();
                    } else if (playerStatus == MediaStatus.IDLE_REASON_INTERRUPTED) {
                        mediaPlayerListener.error();
                    } else if (playerStatus == MediaStatus.IDLE_REASON_ERROR) {
                        mediaPlayerListener.error();
                    }else if(playerStatus == MediaStatus.PLAYER_STATE_IDLE && mediaStatus.getIdleReason() == MediaStatus.IDLE_REASON_FINISHED&& mIdleReason == MediaStatus.IDLE_REASON_FINISHED){
                        mediaPlayerListener.played();
                    }
                }
            }

            @Override
            public void onMetadataUpdated() {
                Log.d("", "onMetadataUpdated: ");
            }

            @Override
            public void onQueueStatusUpdated() {
                Log.d("", "onQueueStatusUpdated: ");
            }

            @Override
            public void onPreloadStatusUpdated() {
                Log.d("", "onPreloadStatusUpdated: ");
            }

            @Override
            public void onSendingRemoteMediaRequest() {
                Log.d("", "onSendingRemoteMediaRequest: ");
            }

            @Override
            public void onAdBreakStatusUpdated() {
                Log.d("", "onAdBreakStatusUpdated: ");
            }
        };

It's not pretty but you can make this call:

if (mRemoteMediaPlayer.getMediaStatus().getPlayerState() ==  MediaStatus.PLAYER_STATE_IDLE
    && mRemoteMediaPlayer.getMediaStatus().getIdleReason() ==  MediaStatus.IDLE_REASON_FINISHED) {
  ...

}
