title: Why is there no Preview in Android Studio for \res\menu\main.xml?
body: <p>I am using Android studio 130.677228. Everything is OK and installed and my project has been built successfully. But I do not have Preview tab for layouts and there is no “Preview” menu in “Tool Windows”</p>
  
  <p>Why? How can I solve this?</p>
