Android Question Question About updates

so when you compile you add the new backgrounds, and then re-upload to google play?
or do you want to update the backgrounds without updating the app? Then you will have to download and store them on DirRootExternal (if they should be accessed by other apps), but if only your app has access then DirInternal.

when i make a update and make upload to google play automatic update my app with new backgrouds?

Yes, the new apk will contain the new backgrounds

hmm thx man
