Screen capture with background service

Question

I started to work with Lollipop & Media.Projection class to implement a screen sharing app. The demo project from Google is quite good enough for me to understand this new feature of Lollipop. But then I found it's hard to make the screen capture goes background since all the time when Home or Back button are pressed, the surface activity is destroyed hence the capturing thread will no longer work. Is there any hint on this situation?

Answer 1

This problem may cause by your application is finished by LMK(low memory killer).

You can pin a fixed notification by using "startForeground" on custom Service to avoid LMK.
