Extract source code from an Android apk file

Step 1:

Make a new folder and put .apk file in it (which you want to decode). Now rename the extension of this .apk file to .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 files, so continue.

Step 2:

Now extract this zip apk file in the same folder (or NEW FOLDER). Now download dex2jar from this link http://code.google.com/p/dex2jar and extract it to the same folder (or NEW FOLDER). Now open command prompt and change directory to that folder (or NEW FOLDER). Then write dex2jar
classes.dex and press enter. Now you get classes.dex.dex2jar file in the same folder. Then download java decompiler from Page on Decompiler and now double click on jdgui and click on open file. Then open classes.dex.dex2jar file from that folder. Now you get class files and save all these class files (click on file then click "save all sources" in jdgui)
by src name. At this stage you get java source but the xml files are still unreadable, so continue.

Step 3:

Now open another new folder and put these files

1. put .apk file which you want to decode
2. download apktool v1.x AND apktool install window (both can be
downloaded at the same location) and put in the same folder
3. download frameworkres. apk apk file and put in the same folder
(Not all apk file need frameworkres. apk file)
4. Open a command window
5. Navigate to the root directory of APKtool and type the following
command: apktool if frameworkres.
apk
6. 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.

Step 4:

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