title: Clear Data on update
body: <p>I'm maintaining a long living app on Android, and I've decided to change the data model behind it merging a few SQLite databases into a single new one.</p>
  
  <p>The thing is, if I just create the new DB and stop using the old ones, every app user out there will still have the old SQLite files in their local storage.</p>
  
  <p>Is there a way to force a "clear data" upon a new version of the app?
  (I'm looking for the "right" way to do it, I know I can check if the new DB exists and act according, but I think there may be a better way)</p>
  
  <p>Thanks</p>
