每当我旋转手机或按Home键时应用程序崩溃，我都会遇到以下异常：

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清单中插入以下内容来实现的：

<service android:name="StationService" />

Answer 1

我意识到我的问题是在服务没有受到限制的情况下解锁我的服务。只有取消绑定onPause（）中的服务似乎已经解决了我的问题。

Answer 2

确保您从相同的上下文绑定和解除绑定。我收到此错误并发现这是因为我之前已经实现了一个上下文包装器，我用它绑定了我的服务。我的unbind是在View上下文中，所以它不知道服务绑定/注册。

Answer 3

在应用程序清单文件中注册您的服务。

Answer 4

您的服务在清单中注册不正确。应该是：

<service android:name=".StationService" />

如果服务与清单中指定的包在同一Java包中。

或者，如果Service与清单中注册的Java包不同，那么您需要指定完整的包名称：

<service android:name="com.example.package.StationService" />

导致此IllegalArgumentException的原因是：服务未注册？
