title: Clearing app cache programmatically?
body: <p>I want to write a utility where the user can select a set of installed apps and clear their data caches i.e. like the way you can do manually using the built-in Settings->Applictions settings screen with the "Clear cache" button.</p>
  
  <p>How can I access how much cached data each app has and programmatically clear these caches?</p>
