当客户端应用连接到这个Service时，onServiceConnected方法将被调用，客户端就可以获得IBinder对象。参看下面的客户端onServiceConnected方法：

view sourceprint?01private ServiceConnection sc = new ServiceConnection() {

02

03 @Override

04 public void onServiceDisconnected(ComponentName name) {

05 musicService = null;

06 Log.d(TAG, "in onServiceDisconnected");

07 }

08

09 @Override

10 public void onServiceConnected(ComponentName name, IBinder service) {

11 musicService = IMusicControlService.Stub.asInterface(service);

12 Log.d(TAG, "in onServiceConnected");

13 }

14 };
