HOWTO: Get Application Specific Directory -ASD (where one exists) without Extensions

I don't mind where the selfie files are, as far as the app can retrieve them to show them to the user, and the user can't delete them.

Of course, the user can delete any file on his device from the external storage (also from the ASD). See e.g. here. The only files that the user cannot access without rooting the device are the assets.
