Я разрабатываю приложение Radio для устройств Android, которое должно получать потоковую передачу с сервера Shoutcast.
Звук работает нормально, но я также хочу получить метаданные, чтобы я мог показать название текущей воспроизводимой песни, исполнителя, а также изображение альбома.
Я использовал MediaMetaDataRetriever, но, похоже, он вообще не работает!
Это код, который я использовал:
public class MainActivity extends FragmentActivity {
private ImageView bannerView;
private int[] pub = {R.drawable.banner, R.drawable.pubnautic, R.drawable.pubquad};
private int i = 0;
private ImageView play;
private ImageView pause;
private TextView title;
private MediaPlayer mediaPlayer;
private MediaMetadataRetriever retriever;
private String out;
private String url = "http://streamplus8.leonex.de:14910";
