title: deploy extra data files to deployed android app
body: <p>Consider an app with a set of data files (could be music or pictures or locations or indeed anything at all) embedded in the apk.
  I now want to provide to the user additional data files , either to replace or add to the original data files - the user should be able to select which files to download and not have to reinstall the whole app.</p>
  
  <p>So the question is it possible to do this non-programmatically - like by providing extra apk files for the app but which only contain single data files?</p>
