From APK to readable java source code in 3 easy steps

Android applications are packed inside a APK file, which is just a ZIP file containing among other things a compactDalvik Executable (.dex) file.

First step is to extract the “classes.dex” file from the APK:

Now, we use the tool dex2jar to convert the classes.dex file to Java .class files:

From here we obtain the file “classes.dex.dex2jar.jar”, now we can use the java decompilerJD-GUI to extract the source code:

Now just go to “File -> Save all sources” and it will generate the zip file “classes.dex.dex2jar.src.zip” containing all the decompiled Java source code
