活动停止后IntentService停止

activity 它约束了 connection 到a IntnetService .该服务只是起到了 MediaPlayer onDestroy 服务内部。然而,在按下main activity中的back之后,我原本希望该服务能够像IntentService假设的那样在后台以单独的线程运行,但在调试之后,我意识到了这一点 onDestory 活动来电 IntentService

Activity

public class MainActivity extends AppCompatActivity{

    private void startAudio() {
        Intent intent = new Intent(Intent.ACTION_SYNC, null, this, PlayerService.class);
        bound = bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);

    }
}

这是我的 Service :

public class PlayerService extends IntentService{
    @Override
    public void onDestroy() {
        mediaPlayer.pause();
        mediaPlayer.reset();
        mediaPlayer.release();
    }
}
