Android and Native Decompilation Skill

Use this skill whenever you need to automate the decompilation of Android apps (.apk or extracted classes.dex) and native libraries (.so).

Decompiling Java (classes.dex -> .java)

Use the following Docker command to download and run Jadx statelessly (without needing an installation):

docker run --rm -v "$(pwd):/app" ubuntu:latest bash -c "
  cd /app
  apt-get update && apt-get install -y wget unzip default-jre
  wget -qO- https://github.com/skylot/jadx/releases/download/v1.4.7/jadx-1.4.7.zip > jadx.zip
  unzip -q jadx.zip -d jadx
  ./jadx/bin/jadx -d /app/apk_decompiled /app/path/to/classes.dex
  rm -rf jadx jadx.zip
"

Decompiling C/C++ (.so -> .c pseudo-code)

Use the devrvk/so-decompiler Docker image to extract pseudo-code using Ghidra Headless and Angr.

docker run --rm --platform linux/amd64 -v "$(pwd):/app" devrvk/so-decompiler decompile /app/path/to/library.so /app/so_decompiled/output_folder_name

Ready-to-Use Script

For standard PS Vita Android ports, a script named decompile_all.sh can be written to the project root to automate this entirely.
