title: Android Studio Rendering fragment issue
body: <p>I am, at the moment, trying to make a google maps app using android studio.</p>
  
  <p>Right now, everything is fine, except for one thing, when i go to the "Design" Tab, in the XML file i have this Redering message:</p>
  
  <blockquote>
    <p>Rendering Problems A tag  allows a layout file to
    dynamically include different layouts at runtime. At layout editing
    time the specific layout to be used is not known. You can choose which
    layout you would like previewed while editing the layout...</p>
  </blockquote>
  
  <p>And the main problem is that I cannot use any of the gui components in my layout, I searched about my problem and i understood that with this error, people couldn't see their map but they could put on textfields, widgets, layouts, etc.
  But for me, my preview is completly frozen and i can't do any modification.</p>
