windowBackground in Android 6 (Marshmallow)

Question

I have defined a base style for my application with the following element:

@color/window_background         


        

Answer 1

I used to have a same problem, but I found out by trying that if I commented actionBarTheme in my styles, it started to work suddenly. I dug deeper in my styles and found out that the style of action bar was setting a android:background attribute after commenting it out everything works now as expected.
