How to Convert APKs to JARs

1. Open a Web browser and navigate to the 'dex2jar' page on Google Code (see Resources). Click on the 'Downloads' link at the top of the page, and then click on the 'dex-translator-0.0.9.4.zip' link on the next page. Save the archive to your hard disk drive.

2. Right-click on the downloaded archive and select 'Extract All' from the context menu that opens. Select the desktop and press 'Enter' to extract the contents of the archive on your desktop. Copy the APK file to your desktop.

3. Open the Windows 'Start' menu, type 'cmd' (without quotes) in the Run box and press 'Enter' to start the Windows command prompt tool.

4. Type 'cd desktop' (without quotes) at the command prompt and press 'Enter' to point the prompt to your desktop.

5. Type 'dex2jar app.apk' (without quotes) at the command prompt. Replace 'app' with the exact name of your APK file. Press 'Enter' to convert the APK file to a JAR. The JAR file is created on your desktop and is named 'app.apk.dex2jar.jar.' You can change its name but always keep the '.jar' filename extension.
