title: How to force app uninstall in order to update?
body: <p><br />
  I did a mistake that apparently can be solved only by uninstalling and then installing my app again.</p>
  
  <p>I delivered a message to the users, but no-one seems to uninstall it.</p>
  
  <p>AFAIK, if I change the certificate file, the play store won't let me upload the application, and
  obviously I don't want to upload a new app.</p>
  
  <p>Is there a way to force uninstall in order to update?</p>
  
  <p>Thanks!</p>
