Question

我想在按下按钮时完成我的应用程序，但它终止并且 logcat 向我抛出错误。你能看看吗？上面说接收者没有注册，但是我注册了。

按钮代码

stopService(new Intent(MainActivity.this, GPSandSMSService.class));
finish();

GPS和短信服务代码

Answer 1

来自你的LogCat：Receiver not registered

您无法取消注册从未注册过的内容...

您的onCreate只能保证注册1个接收器(SMSChecker),

但是您的 onDestroy 这样做：

@Override
public void onDestroy(){
    super.onDestroy();
    unregisterReceiver(SMSChecker);
    unregisterReceiver(MapAlertReceiver);
}

因此 MapAlertReceiver 仅在某些时候注册，当它未注册并且您尝试关闭应用程序时崩溃。

Answer 2

你好像在打电话：

unregisterReceiver(MapAlertReceiver);

来自onDestroy，但可能尚未注册。
