推荐答案

只要您的应用程序位于前台，就可以使用startService()，如果您的应用程序位于后台并且调用了startService()，则您将获得IllegalStateException

You can use startService() as long as your app is in foreground , if your app goes background and you call startService() you will get IllegalStateException

或者，您可以使用startForeground()来启动服务

Alternatively you can use startForeground() to start a service

从文档

应用程序位于前台时，它可以自由创建和运行前台和后台服务.当应用进入后台时，它会有几分钟的窗口，仍然允许在其中创建和使用服务.在该窗口的末尾，该应用程序被认为是空闲的.此时，系统将停止应用程序的后台服务，就像该应用程序已调用服务的Service.stopSelf()方法一样

While an app is in the foreground, it can create and run both foreground and background services freely. When an app goes into the background, it has a window of several minutes in which it is still allowed to create and use services. At the end of that window, the app is considered to be idle. At this time, the system stops the app's background services, just as if the app had called the services' Service.stopSelf() methods
