我在开发Android的娱乐应用程序。我想播放背景音乐，而我想用服务的。应用程序有3个活动和音乐必须在所有的活动中播放。此外，当活动被暂停，音乐必须暂停并销毁时，停了下来。谁能告诉我如何做到这一点？任何链接或例子？

推荐答案

做没有服务

如果你正如此严重的与服务做使用媒体播放器

If you are so serious about doing it with services using mediaplayer

Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;
    public IBinder onBind(Intent arg0) {

        return null;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        player = MediaPlayer.create(this, R.raw.idil);
        player.setLooping(true); // Set looping
        player.setVolume(100,100);

    }
    public int onStartCommand(Intent intent, int flags, int startId) {
        player.start();
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }
    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }
    public void onPause() {

    }
    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}
