title: Android: Save file permanently (even after clear data / uninstall)
body: <p>I would like to know if there is a way to store a small amount of data permanently.<br>
  By permanently I mean I want the data to persist even if user clears app data / uninstalls app.<br>
  I know that shared preferences and databases are deleted when user clears app data / uninstalls app.  </p>
  
  <p>I also know that I can save stuff on SD Card, but what if device does not have SD Card / 
  SD Card is unmounted?</p>
  
  <p>I think that the best option would be to save the data on device internal memory, but is it possible to do that without getting the data deleted when clears app data / uninstalls app?  </p>
