【问题描述】：
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？它说接收者没有注册，但我有。
按钮的代码
stopService(new Intent(MainActivity.this, GPSandSMSService.class));
finish();

【问题讨论】：
-
根据您的日志，您似乎没有在
onCreate()中注册BroadcastReceiver(com.emmanuilvaresis.oldiefinder.GPSandSMSService)，而在onDestroy()中未注册。 -
@Trinimon，GPSandSMSService 是一项服务。它不是广播接收器。
