Hello guys! I'm just starting my learning curve and I have a rather strange problem, my AVD starts just fine but it doesn't show the real app theme. It constantly shows the same purple header. When i change the color to, say, Material Light/Dark or Holo  Dark/Light or any other it still shows the old purple color. When i change text it show it correctly but somehow it can't show the right color.
Do you have any clues as to what the problem is?

I hope you understand what i mean, i can paste the errors i get if it helps. Thanks!
