contextual action bar with gray overlay

Question

I have a light gray background for the contextual action bar. But on a Nexus 5 I have also a darker overlay and I don't know why :-(

I think the images for the background are okay.

Answer 1

Because you don't have resources for xxhdpi for Action Mode. Use Android Action Bar Styles Generator, generate resources for your Action Bar in the action mode and apply it. It will fix your problem.
