Question

I am implementing an application related to getting current music track information.

I am using the following code to get that:

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");

        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();
        }
    };

}

It is working fine for some mobiles only. I want to implement code to get current music track info in all Android devices (e.g. HTC and Samsung devices).

Is there any way of doing this?

Answer 1

This might help. I use this to get metadata on audio files in one of my apps:

String scheme = mAudioUri.getScheme();
String title = "";
String artist = "";
if(scheme.equals("content")) {
    String[] proj = {MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ARTIST};
    Cursor cursor = this.getContentResolver().query(mAudioUri, proj, null, null, null);
    if(cursor != null && cursor.getCount() > 0) {
        cursor.moveToFirst();
        if(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE) != -1) {  
            title = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE));
            artist = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST));
        }
    }
}

There are lots of columns in the MediaStore.Audio.Media class which you can use to find what you’re looking for I think.
