I'm using Nethunter, and the architecture is Linux arm, and I would love to use the apktool tool, I'm studying and reading pentest books, but I can't practice if I don't apply what's there, the problem is that for me rebuild an apk using apktool b app it returns an error code 131, which according to the creator of apktool, is that aapt is not working for arm architecture, is there any way I can install aapt for arm?
So guys, as it is not possible to use this tool on Android devices, the solution I found was to use the Apk Editor Pro and change the files I need to change, but I found this Haxus tool that works on Android devices and does the same work that apktool
