This code worked for me:

private static final String AVRCP_PLAYSTATE_CHANGED = "com.android.music.playstatechanged";
private static final String AVRCP_META_CHANGED = "com.android.music.metachanged";

private void bluetoothNotifyChange(String what) {
    Intent i = new Intent(what);
    i.putExtra("id", Long.valueOf(getAudioId()));
    i.putExtra("artist", getArtistName());
    i.putExtra("album",getAlbumName());
    i.putExtra("track", getTrackName());
    i.putExtra("playing", isPlaying());        
    i.putExtra("ListSize", getQueue());
    i.putExtra("duration", duration());
    i.putExtra("position", position());
    sendBroadcast(i);
}

Call bluetoothNotifyChange with the appropriate intent (defined above) depending on your playback status: pause/playing/metadata changed.
