Updating an Android Game (without a full APK)

[Jackkel Dragon]

I feel like this may be more of a question for an Android forum, but I'd like to know if there is a way to modify a Ren'Py application on an Android device without creating a full new APK file for each update or change. For instance, a scenario like this:

- Player installs the main game APK (100% size)
- A new update comes out, making full game APK size 105%
- Instead of downloading the full game again, the player downloads the update/addon for the 5%-104% that was changed

Going through the documentation, it looks like the only method may be the Web Updater, which I don't have a server to host files for. Are there other means of injecting files into an application after it is installed, or does it always require a full APK to update?

Android doesn't support the web updater. You'll have to use a storefront, like Google Play. There is (at the time I joined several years ago) a $30USD developers license fee, but after that there are no fees (standard transaction fees excepted if you charge people to buy your game)
