title: Android Studio Failed to load platform rendering library
body: <p>I have a project started from scratch on Android Studio. The layout editor was working fine. After adding the Google Play Services library, now when I open my layout XML file I get the following error in the Design tab:
  "Rendering Problems: Failed to load platform rendering library"</p>
  
  <p>In the Text tab, all the attributes for my TextView components have a warning "Unknown attribute android:[...]" where [...] is the attribute being declared.</p>
  
  <p>Anybody know how to fix this issue?</p>
