<doc incomplete, needs work still ran outa time for now 7/22 @ 351pm digdat0>

This page will show how to take apart the Android APK file and convert the files into readable java format.

Step 1 - Download some files

Download the APK

Download one of these files:

Download a tool to extract the APK

Download dex2jar from

Download a tool to convert files to Java .class files

Download jd-gui from this repo:

Unzip both the dex2jar and the jd-gui apps

Step 2 - Extract the APK

After unzipping the dex2jar file, you need to change to a command prompt (windows) or terminal (mac/'nix).

From the command line, the command is as follows:

d2j-dex2jar.bat -f \path\file.apk

Once this is done, a new JAR file will be created in the same folder. You can now convert that file to extract the .classes from it (the Java content)

Step 3 - Convert the files

Open the jd-gui app

Step 4 - Research the Java classes files

After saving the files, you can then review them in your favorite text editor like notepad++
