Hi 🙂 , here I will explain how to write a simple python script to automate the process of decompiling Android APK files using apktool .jar.

1. First, you need to have apktool.jar installed at location “/usr/local/bin/”.
2. Then, put all the apk files in a directory: “/home/Documents/Project/APKS”.
3. Now, you can simply traverse inside this directory using os.walk (path_to_dir) and decompile each apk using the commands available with apktool.jar
4. Run the python script with this command

python decompileApk.py '/home/kulani/Documents/Project/APKS'

decompileApk.py

import os
import sys
import subprocess

walk_dir = sys.argv[1]
#-------------------------------------decompile----------------------------

i = 0

apktool = "/usr/local/bin/apktool.jar"

for root, subdirs, files in os.walk(walk_dir):
 list_file_path = os.path.join(root, 'my-directory-list.txt') 
 
 with open(list_file_path, 'wb') as list_file:
 for file in files:
 if file.endswith(".apk"):
 i=i+1
 print str(i)+"-"+file 
 os.system("java -jar " + apktool + " d " + root+"/"+file)

Cheers ! 🙂
