title: Data protection on Android
body: <p>I need to protect some data on my Android app. On iOS i can enable data protection and use encryption to save my files. Is there something similar for Android?</p>
  
  <p>My app needs to read and write some images and xmls to an external SD. These images need to be safe. Users should not be able to view these files from a file browser or copy them.  These files should only be accessible by my application. </p>
