I am new to Android development, and I kinda plan to make a game and have it with expansion files that is patched over the time. However, I am yet to see a complete guide on doing this, like creating the patch, looking at the difference of the patched files (different obb files? replace it? etc.) Even if I tested it, I assume I have to upload the APK and publish it first to the Play Store, then test my patch from there.
The thing is, I don’t really want to release it first and then patch things to learn how to do it, especially suddenly everything is broken. As far as I remember from Android page, I have to create a new version of APK every time I have to upload a new patch, this is the side that I am afraid of.
Can someone enlighten me on how I should deal with this? Is test phase in Android dev console allows me to test this out?
