how to extract code of apk file.

step 1:

Download dex2jar here. Create a new java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into  newly created java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

step 2: Download java decompiler here

 One more way

1. Download Dex2Jar zip from this link :http://code.google.com/p/dex2jar/
2. Unzip the downloaded zip file.
3. Open command prompt & write the following command on reaching to directry where dex2jar exe is there and also copy the apk in same directory.
   dex2jar targetapp.apk file(./dex2jar app.apk on terminal)
4. http://java.decompiler.free.fr/?q=jdgui download decompiler from this link.
5. Open ‘targetapp.apk.dex2jar.jar’ with jd-gui File > Save All Sources to sava the class files in jar to java files.
