RemoteControlClient in service, not showing widget

Question

I have an media player service with custom decoders for playing streams. I tried all I could find on the web for registering media control buttons on the screen, but they don't show up.

The service works as it follows:

In onCreate() I did the following:

audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
Intent buttonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
ComponentName component = new ComponentName(this, MediaControlReceiver.class);

buttonIntent.setComponent(component);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, buttonIntent, 0);
myRemoteControlClient = new RemoteControlClient(pendingIntent);

audioManager.registerRemoteControlClient(myRemoteControlClient);

int flags = RemoteControlClient.FLAG_KEY_MEDIA_PREVIOUS
        | RemoteControlClient.FLAG_KEY_MEDIA_NEXT
        | RemoteControlClient.FLAG_KEY_MEDIA_PLAY
        | RemoteControlClient.FLAG_KEY_MEDIA_PAUSE
        | RemoteControlClient.FLAG_KEY_MEDIA_PLAY_PAUSE
        | RemoteControlClient.FLAG_KEY_MEDIA_STOP;
myRemoteControlClient.setTransportControlFlags(flags);

When the service received a play message, I start the song and I call the following code for lockscreen buttons:

int result = audioManager.requestAudioFocus(focusChangeListener,
        AudioManager.STREAM_MUSIC,
        AudioManager.AUDIOFOCUS_GAIN);

if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
    Log.d("RemoteControl", "Status: PLAY"  + result);
    myRemoteControlClient.setPlaybackState(RemoteControlClient.PLAYSTATE_PLAYING);
    setRemoteControlMetadata(null, "test", "test", 1);
}

I also have a focus change listener registered, but with no use. Can you help me connect my application to widget buttons?
