I have created a tool that combines dex2jar, jd-core and apktool: https://github.com/dirkvranckaert/AndroidDecompiler Just checkout the project locally and run the script as documented and you'll get all the resources and sources decompiled.

An APK is just in zip
format. You can unzip it like any other .zip
file.
You can decompile .dex
files using the dexdump
tool, which is provided in the Android SDK.
See https://stackoverflow.com/a/7750547/116938 for more dex info.

You can also use the apktool: http://ibotpeaches.github.io/Apktool/ which will also give you the xml res files. Along with that you can also use the dex2jar system which will output the dex file in the apk to a jar file that can be opened with JD-GUI and exported to standard java files.

Also you can use Android Multitool. You can make minor changes in the app like hiding GUI elements or modifying small part of Logic and rebuild the apk. Its easy to use and decompile/recompile apk and jar files. Here is the Link you can checkout.
