Decompressing an apk file

README.md

##Decompressing an apk file

This bash script can be use to decompress an apk file. The script is made as a part of an ongoing project!

###Usage

./decompress.sh -d <path to apk file>

###Dependencies

• Java Jdk
• dex2jar http://code.google.com/p/dex2jar/
• jd-gui viewer http://jd.benow.ca/

###Note: Edit the DEXPATHvariable accordingly with the path to dex2jar folder.

Sometimes the jdgui viewer doesn't render files correctly when opened from commandline, so opening them manually works currently.

decompress.sh

#!/bin/bash

DEXPATH="/home/sushant/Downloads/dex2jar-0.0.9.15"   
JDGUI="/home/sushant/Downloads/jd-gui/jd-gui"

while getopts ":d:" opt; do
  case $opt in
    d)
      mkdir -p $OPTARG"_FILES"
      cp $OPTARG $OPTARG"_FILES"
      cd $OPTARG"_FILES" ; mv $OPTARG $OPTARG".zip" ; jar xvf $OPTARG".zip" ; cd ../ 
      $DEXPATH/d2j-dex2jar.sh -f $OPTARG"_FILES"/classes.dex ;
      echo "Done decompressing!"
      echo "you can view the classes-dex2jar.jar file using jdgui viewer"
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :)
      echo "Option -$OPTARG requires an argument." >&2
      exit 1
      ;;
  esac
done
