    Accessing files on external storage

    If you’re using API Level 8 or greater, use getExternalFilesDir() to open a File that represents the external storage directory where you should save your files. … If the user uninstalls your application, this directory and all its contents will be deleted.

    From my understanding this will create a file on the sd card which has a scope (like a directory of your applications package namespace) and the phone will delete the directory when you uninstall the app. I assume this is how Google apps achieves this function.
