Steps to get JAVA files from .apk file :

Rename and get dex2jar file

 

• Rename the .apk file into .zip file (example pcmadness.apk into pcmadness.zip).
•  Extract pcmadness.zip file and copy classes.dex file from extracted folder.
•  Extract dex2jar.zip and paste classes.dex into dex2jar folder. 
•  Open command prompt and change directory to the dex2jar folder. Then write dex2jar classes.dex and press enter.

 Now you will get classes.dex.dex2jar file in the same folder.

Convert classes.dex to classes.dex.dex2jar

classes.dex.dex2jar will be in dex2jar folder

• Now open jd-gui(Java decompiler) and click on open file. 
• And then open classes.dex.dex2jar file from that folder.

 Now you will get class files and save all these class files by clicking on file then click “save all sources” in jd-gui by src name.

Steps to get XML files from .apk file:

• Download apktool.bat (or apktool for Linux) and apktool_<version>.jar from http://ibotpeaches.github.io/Apktool/install/ rename the jar file from above to apktool.jar and put both files in the same folder.
• Open a cmd.exe and change into that folder; verify that a Java Environment is installed (for Linux check the notes regarding required libraries as well)
• Now type apktool decode [apk file] in cmd.

 Congrats,
You now successfully took the source from the app. This is for educational purpose only.
