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?
When you're talking about icon packs, do you mean to replace the app icons in your launcher?
To my understanding, there are launchers that would allow you to install a custom icon pack, but most default launchers won't allow you to customize the icons.
The launcher I made has a mechanism for creating your own icon packs, and I also have a built-in tool for creating nice-looking monochrome icons from the originals. If you're into a more minimalistic approach, give it a try.
Indeed - it's the icons on my home screen (and the rest of the pages)
And thanks for the pointer to your launcher but there's something unusual with the device I have along with the OS (I think it's OxygenOS 14) - your launcher (eg) can't be installed or used as such and I have to start with an apk (that eventually appears in a window where you can select that collection and also select one of the icons inside)
