Android:调用 onStop() 时为 `java.lang.IllegalArgumentException: Service not registered`

Question

我有一个应用程序绑定(bind)到一个长期运行的服务。 我需要确保当用户离开 Activity 时，Service 会停止。

因此我实现了 onStop() 来关闭服务:

代码如下:

@Override    
protected void onStop() {
super.onStop();     
if(mService!=null)mService.stop();
stopService(new Intent(this, LocalService.class));
unbindService(mConnection);
stopService(intent);

}   

这是我的 LogCat:

感谢您的帮助!!!

Answer 1

关键是在onStop()之后，onDestroy()随后被调用。

但是我的 onDestroy() 是:

@Override    
protected void onDestroy() {
    super.onDestroy(); 
    if(mService!=null)mService.stop();
    stopService(new Intent(this, LocalService.class));
    unbindService(mConnection);
    stopService(intent);        

 }

因此我试图两次关闭该服务。但是服务在 onStop() 中已经断开。

谢谢
