Easy steps to Decompile Android APK file into Java code

Now i am going to tell you, how to decompile APK file

we need following
Tools :
Download the followings first.

• Dex2jar from http://code.google.com/p/dex2jar/
• JD-GUI from http://java.decompiler.free.fr/?q=jdgui
• ApkTool from http://code.google.com/p/android-apktool/

Using ApkTool

- to extract AndroidManifest.xml and everything in res folder(layout xml files, images, htmls used on webview etc..)

Run the following command :

1	apktool.bat d sampleApp.apk

It also extracts the .smali file of all .class files, but which is difficult to read.

You can achieve this by using zip utility like 7-zip.

Using dex2jar

- to generate .jar file from .apk file, we need JD-GUI to view the source code from this .jar.

Run the following command :

dex2jar sampleApp.apk

 

 

Decompiling .jar JD-GUI

- it decompiles the .class files (obsfucated- in case of android app, but readable original code is obtained in case of other .jar file). i.e., we get .java back from the application.

Just Run the

 

jd-gui.exe and File->Open to view java code from .jar or .class file. Now enjoy like Developer. try it,
