Android服务:onServiceConnected()永远不会在绑定时调用

有许多相同标题的问题,但它们没有帮助。所以我在问。

我有一项服务在第一次活动中成功启动。当切换到第二个活动时,我需要bind使用该服务。但是永远不会调用onServiceConnected

(注意:我使用emulator,并使用this example来实现绑定)

活动:

public class GameActivity extends NativeActivity implements GroupInfoListener 
{   
    public SimmobBroker broker;// <- this is my service
    ServiceConnection cnn= new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name,
                IBinder service) {
            Log.i(TAG,"onServiceConnected");
            SimmobBrokerBinder binder = (SimmobBrokerBinder) service;
            broker = binder.getService();
            Log.i(TAG,"onServiceConnected...now initializing the activity");
            InitializeActivity();           
        }
        @Override
        public void onServiceDisconnected(ComponentName name) {
        }
    };  

        @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        Intent intent = new Intent(this, SimmobBroker.class);
        getApplicationContext().bindService(intent, cnn, getApplicationContext().BIND_AUTO_CREATE);
//      InitializeActivity();
    }
};

服务

public class SimmobBroker   extends Service {
    @Override
    public void onCreate() {
        Log.i(TAG, "SimmobBroker Created");
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i(TAG, "SimmobBroker onStartCommand");
        myHandler.post(simmobConnect);
        return START_STICKY;
    }

    @SuppressLint("HandlerLeak")
    public final Handler myHandler = new Handler() {/*...*/}

    private final IBinder myBinder = new SimmobBrokerBinder();

    public class SimmobBrokerBinder extends Binder {
        public SimmobBroker getService() {
            return SimmobBroker.this;
        }
    }
    @Override
    public IBinder onBind(Intent intent) {
        return myBinder;
    } 
};

感谢您的帮助。

尝试直接调用bindService,而不是从应用程序上下文调用。

bindService(intent, cnn, Context.BIND_AUTO_CREATE)
