title: Require users to uninstall previous Android app version on update
body: <p>My client has an app that is released on Google Play and we are in the process of releasing an update. Much has changed in the app and due to previous developers not maintaining the code we are forced to do a clean install to get the app to work (without spending countless hours tracking down changes and writing migration scripts).</p>
  
  <p>Is there a way to force users to uninstall-reinstall (or automatically uninstall-reinstall) the app on an update?</p>
