step 1:
=========

make a new folder and put .apk file (which you want to decode) now rename this .apk file with 
extension .zip (eg:rename from filename.apk to filename.apk.zip) and save it..now you get 
classes.dex files etc...at this stage you are able to see drawable but not xml and java file...
so cont...

step 2:
=======

now extract this zip apk file in the same folder(in this eg or case NEW FOLDER). now dowmload 
dex2jar from this link http://code.google.com/p/dex2jar/ and extract it to the same folder 
(in this case NEW FOLDER).....now open command prompt and reach to that folder (in this case 
NEW FOLDER)....after reaching write "dex2jar classes.dex" and press enter.....now you get 
classes.dex.dex2jar file in the same folder......now download java decompiler from 
http://java.decompiler.free.fr/?q=jdgui and now double click on jd-gui and click on open
 file then open classes.dex.dex2jar file from that folder...now you get class file...save all
 these class file (click on file then click "save all sources" in jd-gui)..by src name....at 
this stage you get source...but xml files are still unreadable...so cont...

step 3:
=========


now open another new folder and put these files

    put .apk file which you want to decode

    download apktool using google and put in the same folder

    download framework-res.apk file using google and put in the same folder

    Open a command window

    Navigate to the root directory of APKtool and type the following command: 

apktoolif framework-res.apk

    apktool d "fname".apk ("fname" denotes filename which you want to decode)

now you get a file folder in that folder and now you can easily read xml files also.

step 4:
=========


it's not any step just copy contents of both folder(in this case both new folder)to the single one

and now enjoy wid source code...
