Solution 1:

What you are trying to do only works for Android level >=21.

See here: Support for referencing theme attributes in drawable XML

From what I read it was a bug... You can read some more on this problem here or here.

Solution 2:

Have you added

      <item name="colorAccent">@color/colorAccent</item>  

in your styles xml for below lolipop version?
