MASTG-TOOL-0012: apkx
apkx is a Python wrapper to popular free DEX converters and Java decompilers. It automates the extraction, conversion, and decompilation of APKs. Install it as follows:
git clone https://github.com/muellerberndt/apkx
cd apkx
sudo ./install.sh
This should copy apkx to /usr/local/bin. See Decompiling Java Code for more information about usage.
