Question

我知道有很多关于这个问题的问题，我几乎看到了所有问题，但我无法解决我的问题。我有一个服务，使用本地广播管理器调用主要活动，我从这个服务获得一些价值，然后我把它们放入字符串并发送到需要使用它们的其他服务。其中一个服务调用本地广播，但其中两个在按钮监听器中，我使用警报管理器每1分钟重复运行它们，我也在第一个服务中使用satrtforeground（）调用主要活动，但奇怪的是在设备中的某些设备屏幕下车或用户从后台（从堆栈）清理应用程序服务不起作用。我希望你能帮助我，谢谢

Answer 1

确保您在退出时没有结束应用程序的过程。使用

finishAffinity();

退出应用。

Answer 2

取决于设备的型号。如果从应用程序堆栈中删除应用程序，则不同的设备会有不同的行为。

某些设备可以停止应用程序进程，并且不会启动任何一个警报管理器，但是其他设备仅关闭活动但进程处于活动状态。

尝试使用https://stackoverflow.com/a/16698105/2930077确定进程是否存在

当应用程序完全关闭时，我的服务无法运行
