Online APK Decompiler
APK Decompiler App for Windows

Update 2015/12/04
ClassyShark you can open APK/Zip/Class/Jar files and analyze their contents.


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.



This website will decompile the code embedded in APK files and extract all the other assets in the file.

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.
