title: Rendering problems in Android Studio v 1.1 / 1.2
body: <p>When I add <code>android.support.v7.widget.Toolbar</code> or another <code>android.support.v7.widget.*</code> there are rendering problems. </p>
  
  <p>But <em>Support Library</em> is up to date. And I complied in dependecies properly. I can import them in <code>MainActivity.java</code></p>
  
  <p>What is the problem?</p>
