title: Android - Action Bar doesn't show up using Theme.AppCompat
body: <p>I am trying to use <code>Theme.AppCompat</code>, but when I do the Action Bar simply disappear. There is no errors or whatsoever.</p>
  
  <p>The thing is I'm using this exact setting on two more projects and they work just fine, not sure what changed. </p>
  
  <p>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.</p>
  
  <p>I am using Android Studio 0.8.14</p>
  
  <p>Correct me if I'm wrong but that's how I use Material Theme widgets and color palette on older API's, right?</p>
