By default, 4.0 and 4.1 give us a white background, but you can change it to black. I am facing the same problem a few days ago, if your project theme is set to black, maybe you change the name by creating the project to “Main”, by default its “MainActivity”, but if you change it to “Main”, it will give you black backgrount /
I don’t know if my answer relates to your question or not, but I think you are talking about it if I’m not mistaken.
