title: How to distribute updates to users of pre-installed paid Android App?
body: <p>I wrote a small Android app. It is published on Google Play as two distinct versions</p>
  
  <ul>
  <li>a free demo version with limited features</li>
  <li>and the paid version without limitations</li>
  </ul>
  
  <p>Now I have been approached by the distributor of a tablet who wants to pre-install my app on his device. Obviously, I want the owners of his product to benefit from later updates for my app.</p>
  
  <p>Is there a way to pre-install the paid app on the device <em>and</em> still allow free updates to the app?</p>
  
  <p>Thanks!</p>
