I see a lot of apps that uses notifications to stay running and avoid being killed, but i don't know how to implement it. Can someone help me achieve this?

Answer 1

You can use the Service API for this, specifically the startForeground(int, Notification) function call. There is an example provided in the API documentation that I have linked to.

Answer 2

服务或AlarmManager是您要寻找的，取决于您要执行的操作。

Answer 3

Use Android Services .You can use the following methods:-

1. To call a Service which doesnt return any value back use - startService()
2. To call a Service which return back values use - bindService()

Its good to be cautious when using any Sensors to run in the background as it might eat up you battery fast
