android - 是什么导致了这个 IllegalArgumentException : Service not Registered?

Question

每当我旋转手机或按下主页按钮时，应用程序就会崩溃，并且出现以下异常:

这是mConnection

  /** Defines callbacks for service binding, passed to bindService() */
private ServiceConnection mConnection = new ServiceConnection() 
{

    @Override
    public void onServiceConnected(ComponentName className,
            IBinder service) {
        // We've bound to LocalService, cast the IBinder and get LocalService instance
        LocalBinder binder = (LocalBinder) service;
        mService = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName arg0) {
        mBound = false;
    }
};

我已经注册了我的服务 - 至少我认为我是通过在我的 list 中插入以下内容来注册的:

<service android:name="StationService" />

我意识到我的问题是在服务最初没有绑定(bind)的时候取消绑定(bind)我的服务。只有在 onPause() 中解绑服务似乎已经解决了我的问题。
