My app is already using Holo but when I added chromecast support it was required that I use the v7 support ActionBarActivity or at least FragmentActivity. Both of these require me to use an AppCompat theme from what I can tell. Is that true? Does adding a feature like google cast really require you to change your theme? The reason I resist changing to an appcompat theme is because it breaks allot of the custom styling I created.
So in conclusion it sounds like for now the answer is no its not possible. Based on the comments from Ali and commonsware. At least without using unofficial sdk code which I do not want to do.
