【问题描述】：
嘿，我有服务它的壁纸服务（不是动态壁纸），所以当我进入应用程序时，我有 5 个单选按钮，每个按钮决定壁纸改变的时间，我有一个触发服务的按钮，我得到了我的响应服务器即使我关闭应用程序但是....当我重新启动设备时，我只得到 1 个响应并且壁纸没有改变可以说我被选择每 4 秒更改一次，就在我重新启动它停止时，就像我说我收到我的服务器只有一个响应，甚至壁纸都不会随着这个响应而改变看看我的代码你会理解更多（我使用了接收器和启动权限，但是......）；

【问题讨论】：
-
您正在测试的设备或模拟器的 Android 版本是什么？
-
我想我的服务正在运行，但是带有单选按钮的警报管理器在重启时不起作用
-
设备重启后，alarmManager 不会记住您的设置。你需要在receiver的onReceive中再次初始化
-
我应该在接收器中复制粘贴我的主要活动吗？？
-
帮助?!!?!?!?!?,
