remoteMediaPlayer.requestStatus(...) returns statusCode SIGN_IN_REQUIRED

I have a radio application which plays live radio stations on Google Chromecast. Starting a stream with remoteMediaPlayer.load(...) works just fine. But remoteMediaPlayer.requestStatus(...) for later stopping the stream says statusCode=SIGN_IN_REQUIRED and throws a IllegalStateException: No current media session

Why can't I stop the playing live radio stream? Or how can I stop the remoteMediaPlayer playback?

The live radio streams are HTTP. Can it be the problem?

Here the details:

The following code starts the stream and it works.

    MediaMetadata mediaMetadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_MUSIC_TRACK);
    mediaMetadata.putString(MediaMetadata.KEY_TITLE, stationName);
    mediaMetadata.addImage(new WebImage(Uri.parse(imageUrl)));
    final MediaInfo mediaInfo = new MediaInfo.Builder(stationUrl).setContentType("audio/mp3").setStreamType(MediaInfo.STREAM_TYPE_LIVE)
            .setMetadata(mediaMetadata).build();
    try {
        mRemoteMediaPlayer.load(apiClient, mediaInfo, true).setResultCallback(new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {
            @Override
            public void onResult(MediaChannelResult result) {
                if (result.getStatus().isSuccess()) {
                    Utils.log(TAG, "Media loaded successfully: " + result.getStatus());
                } else {
                    Utils.log(TAG, "Media loaded NOT successfully: " + result.getStatus());
                }
            }
        });
    } catch .... {

The following code stops the stream and it does not work. The result ist statusCode=SIGN_IN_REQUIRED and java.lang.IllegalStateException: No current media session

public static void stop() {
    try {
        mRemoteMediaPlayer.requestStatus(apiClient).setResultCallback(new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {

            @Override
            public void onResult(RemoteMediaPlayer.MediaChannelResult mediaChannelResult) {
                Status status = mediaChannelResult.getStatus();
                Utils.log(TAG, "RemoteMediaPlayer requestStatus: Status=" + status.getStatus());
                try {
                    mRemoteMediaPlayer.stop(apiClient);
                } catch (Exception e) {
                    Log.e(TAG, "Exception while stopping GoogleApiClient. ", e);
                }
            }
        });
    } catch (IllegalStateException e) {
        Log.e(TAG, "Problem occurred while geting requestStatus", e);
    } catch (Exception e) {
        Log.e(TAG, "Exception while geting requestStatus. ", e);
    }
}

Solution

  • toString() isn't really a good way to get the status code. RemoteMediaPlayer has its own set of STATUS_* codes. SIGN_IN_REQUIRED is 4, which is RemoteMediaPlayer.STATUS_REPLACED which means that you issued another request of the same type as this request. The RemoteMediaPlayer, by design, will only track one request of each type. For example, if you send a PAUSE followed by another PAUSE before the first PAUSE request has completed (i.e., received a reply from the receiver), it will stop tracking the first PAUSE and report this error.
