title: How to solve the issue of Android Studio 3 (3.1 canary) Preview: Cannot import project
body: <p>I am working on Android Studio 3 Preview at the moment. However, whenever I tried to open an old project it says:</p>
  
  <blockquote>
    <p>The project file specified already exists.</p>
  </blockquote>
  
  <p>I have deleted:</p>
  
  <ol>
  <li>Old code/project from hard disk (completely)</li>
  <li>Removed the project from the project list.</li>
  </ol>
  
  <p>Any tips on this?</p>
