Icon pack creation tutorial with Android Studio ?

Hi there,

Only 2 weeks ago, I was on a jailbroken iOS device and got fed up with it (and everything that Apple produces - mostly because it's closed down and some proprietary crap like iTunes). And the reason I jailbroke my phone, was mostly for the theming options (place a .png with a specific app name in the folder, select it and that's it)...

Switched to a Oneplus12 last week, loving it, so easy to tweak things out of the box and installed some free icon packs but I can't seem to figure out how to proceed in creating my own icon pack (for personal use). Had a look inside an apk and I have now a basic understanding of the resources inside but swapping out files in an apk isn't the way to go (CRC check done by Android?). Had a look around and installed Android Studio but are there any up-to-date tutorials out there?

thanks! /d
