I tried extracting apk file using apktool. I followed steps mentioned below. Is there a way to get the source code from an APK file?
but i am not able to get it complete
I would create a folder called "apktool" somewhere where it won't be deleted ( a safe spot ).
Download the wrapper file & the apktool file itself via the Google code page (linked below). This is 2 files. One is a wrapper, OS specific, along with aapt ( which is needed for rebuild), and the other is simply apktool.jar which is the main application.
Once that is done, go into Environment Variables (PATH) for Windows, and add that current directory to it. So you can access apktool / aapt anywhere via command prompt.
