Hello there,

I have a question regarding possible best practices using Android APK 
expansion files (OBB).

We have an app with a larger *main expansion file. *Developer docs 
recommend pushing updates to users using a *patch expansion file.* When 
having a "bigger update" (lets say approximately half the size of the main 
file) that replaces large parts of the main file, wouldn't it be better to 
provide a new main file.

It isn't quite clear which approach is more useful:

   - When using a patch file new users would need to download the main 
   file, as well as the patch file - resulting in two large downloads, where 
   only one large download (an updated main file) would also work.
   - On the other hand, when updating the main file to a new version, 
   existing users would need to download the whole content again (where only a 
   patch would do the same).

Best way, would be a updated main file for the new APK version - this can 
be downloaded by new users - plus a patch file for existing users.

Is it possible to have following expansion file structure

   - main.5.my.application.obb, and
   - patch.5.my.application.obb

when uploading a new APK update with appVersion 5 in Manifest?

Thanks for the information!
