我是android编程新手。我有一个问题，我的应用程序的通知后，重新启动它消失

我的应用程序是关于自动转发短信，它也可以通过短信ba启用。我希望在应用程序启用时显示通知。我对通知有两个问题：

1.重新启动后通知消失

2.当通过短信启用应用程序时，通知不会出现

这是我的密码：

您需要创建一个后台作业（android服务），该作业将在重新启动后运行，并查找保存的通知并显示它们。您的应用程序在重新启动后被终止，因此Android无法与其通信并显示通知

首先写一个“服务”，将通知逻辑移到那里。然后编写一个“BroadcastReceiver”，它将监听“android.intent.action.BOOT_COMPLETED”操作。当您收到此操作时，启动您的服务。
