title: Cannot refactor Android Studio Project
body: <p>I have copied a current project of Android Studio to a new directory. I will be using the same coding for another app. </p>
  
  <p>I open the project in Android Studio, and click on the "Java" folder, but it doesn´t show any files inside (they do appear in the hard-drive). </p>
  
  <p>When I click to "Refactor" the "Java" folder the following message appears "Cannot perform refactoring. Selected directory is not located inside project". </p>
  
  <p>Can someone help me to solve this, thanks.  </p>
