  <p>I have tried the following according to this thread (<a href="https://stackoverflow.com/questions/14450209/intellij-idea-ce-12-android-xml-code-completion-not-working">Intellij IDEA CE 12 Android XML Code Completion not working</a>):</p>
  
  <ol>
  <li><p>Go to File->Power Save Mode and disable it - it is off.</p></li>
  <li><p>Go to Preferences->Editor->Code Completion and check Autopopup code completion - this has been checked</p></li>
  <li><p>Go to File->Invalidate Caches and restart. - done and no change</p></li>
  </ol>
  
  <p>What is it that I'm doing wrong?</p>
