推荐答案

您可以在 前台 使用 startForeground().

前台服务是一种被认为是某种东西的服务用户主动知道，因此不是系统的候选人内存不足时杀死.

A foreground service is a service that's considered to be something the user is actively aware of and thus not a candidate for the system to kill when low on memory.

但请记住，前台服务必须为状态栏提供通知(阅读此处)，并且除非服务停止或从前台移除，否则无法取消通知.

But bear in mind that a foreground service must provide a notification for the status bar (read here), and that the notification cannot be dismissed unless the service is either stopped or removed from the foreground.

注意:这仍然不能绝对保证在内存极低的情况下服务不会被杀死.这只会使它不太可能被杀死.

Note: This still does not absolutely guarantee that the service won't be killed under extremely low memory conditions. It only makes it less likely to be killed.
