Android - Action Bar doesn't show up using Theme.AppCompat

Question

I am trying to use Theme.AppCompat, but when I do the Action Bar simply disappear. There is no errors or whatsoever.

The thing is I'm using this exact setting on two more projects and they work just fine, not sure what changed.

I also tried changing support library version, parent theme, cleaning the project, rebuilding and invalidating cache. Wasn't sure if any of that would help but I did anyway.

I am using Android Studio 0.8.14

Correct me if I'm wrong but that's how I use Material Theme widgets and color palette on older API's, right?

My answer should be as a comment but this is the only way I can reply. Are you extending ActionBarActivity in your activity? Have you tried the show() method in your activity?
