I want my application (written in Java) to change the desktop pattern (background) in Android, after e.g. click on "change background to cats.png" button (in my application).

And I want that change to be made constant. When somebody change the background with my application and then turn it off or un-install it, the cats.png will still be the background of the system (till user will change it manually).

Also, I want to make it automatically - user press button => background of desktop being set (without any additional confirmations, fields, windows etc.)
