android expansion file update

Question

I have published a apk but now I want to change few images in expansion file, is there any way to update only expansion file without uploading new apk ? If yes what about users already downloaded app with old expansion ?

Answer 1

It's very well documented in the long description on Android Developers guides.

To summarize.

You always need to update the application code in order for the new expansion files being downloaded. You got a patch and a main expansion file. If you make any update to either your users have to download whole the updated file. So if you can stick with only updating the patch with some minor stuff your doing good and your users will only download the new patch file and the old main will stay with your users unspoiled.
