title: Change package name of android app in alpha version
body: <p>I want to change the package name of my app before publishing as production version. I started this project and development under test package name, so before production I want to change it to a meaningful one. My app has in-app purchase, google leaderboard as well, so the app is published as alpha version now for testing these features. </p>
  
  <p>I want to know</p>
  
  <ol>
  <li>How to change the package name in android studio</li>
  <li>How to change the package name in google developer console.</li>
  <li>How to update inapp purchage items and leaderboard </li>
  </ol>
  
  <p>Can these be done? or do I have to create a new listing on google developer console forgetting about current alpha version?</p>
