推荐答案

@Sohail Zahid (答案)告诉您一种repeatedly再次启动服务 的方法.但是为了使服务保持活力，就像在后台播放歌曲一样.

@Sohail Zahid Answer tells you a way to repeatedly start a service again and again when stopped. But in order to keep a service alive like playing a song in a background.

我发现的最佳方法是

startForeground(int, Notification)

每个通知的int值必须唯一

where int value must be unique for every notification

您需要为进行中部分的通知栏中显示的方法提供Notification. 通过这种方式，应用程序将在后台保持活动状态，而不会发生任何干扰.

You'll need to supply a Notification to the method which is displayed in the Notifications Bar in the Ongoing section. In this way the app will keep alive in background without any interuption.
