APKTool is amazing! I wrote an article on how to do end-to-end reverse engineering of Android apps using APKTool: https://yasoob.me/posts/reverse-engineering-android-apps-apk...

I love using Jadx (https://github.com/skylot/jadx) to get a better understanding of the code in Java and then use APKTool to reverse engineer, decompile and recompile the app

If you are interested, Frida is also an amazing tool that makes certain type of reverse engineerings a lot easier compared to using APKTool. I wrote an article on that as well: https://yasoob.me/posts/reverse-engineering-nike-run-club-us...

Reverse engineering is a very exciting field and the moment you learn and figure out one concept you realize there is a lot more out there for you to figure out.
