Android 设备锁定一段时间后报警管理器不工作

背景

我的应用程序向用户提供事件通知。通知由版主发送。然而，该应用程序允许版主发送“定时通知”，他们可以选择提前发送特定时间的通知

我的逻辑

当版主发送通知时，他们将发送特定的标签。在客户端，若检测到标签，设备将不会显示通知。相反，它将使用

AlarmManager

并在给定时间设置报警。当在所需时间从

AlarmManager

接收到意图时，广播接收器将发送通知

代码

NotificationService.java

TimedNotifications.java

AndroidManifest.xml

post:/等。但目前为止运气不佳。有些东西不见了。
对于那些在这种情况下寻找答案的不幸的人来说，我的代码非常好用。我刚刚发现，当设备进入睡眠模式时，“”正在杀死/休眠我的应用程序。测试报警管理器功能时，请检查任务管理器或其他节省电池的应用程序
 谢谢。我浪费了两天时间测试我的应用程序。在我的例子中，MI-UI电池节电器正在终止警报。
    //Some other code
