Я пытаюсь включить код из create-a-music-player-on-android-song-воспроизведение в мое приложение, но служба падает при вращении устройства.
в действии ...
@Override
protected void onStart() {
super.onStart();
if (playIntent == null) {
playIntent = new Intent(this, MusicService.class);
bindService(playIntent, musicConnection, Context.BIND_AUTO_CREATE);
startService(playIntent);
}
}
@Override
protected void onStop() {
stopPlay();
musicSrv = null;
playIntent = null;
unbindService(musicConnection);
super.onStop();
}
private void stopPlay() {
if (musicSrv != null)
musicSrv.stop();
}
в службе ... [ОБНОВЛЕНИЕ добавлено в onCreate и onDestroy для жизненного цикла игрока]
@Override
public void onCreate() {
super.onCreate();
songPosn = 0;
player = new MediaPlayer();
initMusicPlayer();
}
@Override
public void onDestroy() {
player.stop();
player.release();
player = null;
super.onDestroy();
}
public void initMusicPlayer(){
// set player properties
player.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnPreparedListener(this);
player.setOnCompletionListener(this);
player.setOnErrorListener(this);
}
public void stop() {
if (player != null)
player.stop(); // << this line crashes after second rotation
}
public void playSong() {
// play a song
player.reset(); // << this line crashes after rotation and play
Song playSong = songs.get(songPosn);
long currSong = playSong.mId;
Uri trackUri = playSong.getUri();
try {
player.setDataSource(getApplicationContext(), trackUri);
}
catch(Exception e) {
Log.e("MUSIC SERVICE", "Error setting data source", e);
}
player.prepareAsync();
}

Я просматривал несколько сообщений об IllegalStateException, но я не вижу ни одного, касающегося аспекта ротации.Я пытался переместить код с onStart на onResume и onStop на onPause, но не повезло.Одна странная вещь заключается в том, что он работает при первом вращении, но вылетает при втором вращении.Во время первого поворота я вижу E/MediaPlayerNative: stop called in state 1, mPlayer(0x0) и E/MediaPlayerNative: error (-38, 0).Это происходит после onResume, но в этот момент не происходит сбой.Он вылетает, если я снова поверну его или попытаюсь использовать службу и воспроизвести песню.

Это не сработало.
Есть идеи?Кто-нибудь, кто успешно создал свой собственный музыкальный сервис?Нужен дополнительный код из моего приложения?Кстати, я пользуюсь услугой, потому что я тоже хочу использовать ее с получателя.
TIA, Mike
