How to rip apps from your Android device on a Linux computer.

• Download the apk.sh script.
• Download the bit.sh script (found here).
• Run the bit.sh file using bit apk.sh apk.

The following steps are if you want to decode the app and look at the underlying code. If you just want the APK, the above scripts are enough.

• Download APKTool from here.
• Run chmod u+x apktool.sh.
• Open apktool.sh.
  • Remove the line that says libdir='$progdir'.
  • In the following line, remove the usage of libdir (i.e. "$libdir/$jarfile" becomes just $jarfile).
• Save and close apktool.sh.
• Move apktool.sh and apktool.jar into /usr/local/bin/.
  • To do this, run the command sudo cp apktool.sh /usr/local/bin, and enter your password.
  • Do the same for apktool.jar
• Open your ~/.bashrc file, and just below the line alias apk='bash apk.sh, add the following lines
  • alias list_apk='adb shell pm list packages
  • alias decode_apk='sudo bash apktool.sh d'

How to use it

• Connect your phone to your computer, and make sure ADB debugging is enabled on your phone.
• List all apps installed on your phone.
  • In the terminal, run the command list_apk | grep <keyword>, where <keyword> is some word that is contained in the app's name.
  • Make sure you make the keyword clear enough to only get one result.
    • For example, "key" may work, but several apps could use the word "key," so narrow it down by using a keyword like "monkey," where it would only pertain to one app.
• Run apk <keyword> to download the APK to your desktop.
  • You may stop here and distribute the APK as is, or you may continue on.
• Use the command decode_apk <filename>.apk, where <filename>.apk is the name of the file generated by the previous step.
• This will generate code that you can examine to find what you want.
  • NOTE: it will not be in human-readable Java.
