I am developing an android app based on DRM. Application is intended to encrypt the (audio,video) files after downloading and getting control access on the files(audio,video)preventing the file(audio,Video) copy and paste and expire documents so they can no longer be viewed. for this i am using android.drm
I have searched a lot but didn't get any result
So please share some sample code that explain how to use DRM framework api.
