这是我的应用中的服务类。 这是一个显示两个图标（imageView）作为system_alert_window的应用程序，这些图标可以打开两个活动。 当启动服务时，几分钟后或者从服务执行一个活动然后回来后，几秒钟后服务已经强制关闭两次。
.ng-invalid{
border: 1px solid red;
}
强制关闭服务时显示这些错误：

答案 0 :(得分：2)
尝试创建Service时出错。
您尚未实现onStartCommand()，因此默认实现返回START_STICKY。这意味着一旦您的服务启动，Android将重新启动它（如果需要），直到服务停止。
你的进程被Android杀死了。这可以在Android决定需要资源的任何时候发生。然后，由于您的服务已从START_STICKY返回onStartCommand()，Android将重新启动您的服务。 Android会为您的Service课程创建一个新实例，并在其上调用onCreate()。在这种情况下，由于您的ConfigMain尚未启动（因为Android终止了该过程），ConfigMain.sp为null。
另外，不要这样做：
int pid = android.os.Process.myPid();
android.os.Process.killProcess(pid);
让Android在准备就绪时自行终止你的进程。
