Get info about audio, playing in another application

Question

How can i get info about source (filedesc. or uri) from which another application playing audio?

In AudioManager there is only isMusicActive() method, which doesn't give any additional information. And because of it isn't my application, i doesn't have any MediaPlayer object.

Register a broadcast receiver for known action intents and handle the broadcast to show or do something with the track information, source:

public class CurrentMusicTrackInfoActivity extends Activity {

    public static final String SERVICECMD = "com.android.music.musicservicecommand";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        IntentFilter iF = new IntentFilter();
        iF.addAction("com.android.music.metachanged");
        iF.addAction("com.android.music.playstatechanged");
        iF.addAction("com.android.music.playbackcomplete");
        iF.addAction("com.android.music.queuechanged");
        iF.addAction("com.htc.music.metachanged");
        iF.addAction("fm.last.android.metachanged");
        iF.addAction("com.sec.android.app.music.metachanged");
        iF.addAction("com.nullsoft.winamp.metachanged");
        iF.addAction("com.amazon.mp3.metachanged");     
        iF.addAction("com.miui.player.metachanged");        
        iF.addAction("com.real.IMP.metachanged");
        iF.addAction("com.sonyericsson.music.metachanged");
        iF.addAction("com.rdio.android.metachanged");
        iF.addAction("com.samsung.sec.android.MusicPlayer.metachanged");
        iF.addAction("com.andrew.apollo.metachanged");

        registerReceiver(mReceiver, iF);
    }

    private BroadcastReceiver mReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            String cmd = intent.getStringExtra("command");
            Log.v("tag ", action + " / " + cmd);
            String artist = intent.getStringExtra("artist");
            String album = intent.getStringExtra("album");
            String track = intent.getStringExtra("track");
            Log.v("tag", artist + ":" + album + ":" + track);
            Toast.makeText(CurrentMusicTrackInfoActivity.this, track, Toast.LENGTH_SHORT).show();
        }
    };

}
