Hi, the problem is your using @android:color/ this is looking for a system color you can delete that and just use the hex value like this android:background= "#fff092b0"

hope this helps

Its not a valid hex nber. Hex numbers are 6 characters long. You have more characters than six. I recommend you select your color in a photo editor(photoshop or paint.net or something) then get the hex number directly from that. The hex you have included will fail.
