Control screen brightness in android using “ Background Service”

问题

Problem:-

I want to control the brightness of screen using a background service in android.

Existing Solutions:-

There are similar question posted in the form in below link:-

Adding screen brightness controls to android application

Why existing solution will not work?

All the solution provided in the link works well with an Activity, but I want to write a Background Service which controls the brightness of the screen.

So can you someone please help me find a solution on this issue.

Thanks in advance
