I find the solution to decompile a file dex to jar from this link http://code.google.com/p/dex2jar/downloads/list but i don't understand how to use it.

Follow the below steps to do so_

1. Rename your APK file(e.g., rename your APK file to .zip Ex- test.apk -> test.zip) & extract resultant zip file.
2. Copy your .dex file in to dex2jar folder.
3. Run setclasspath.bat. This should be run because this data is used in the next step.
4. Go to Windows Command prompt, change the folder path to the path of your dex2jar folder and run the command as follows: d2j-dex2jar.bat classes.dex
5. enjoy!! Your jar file will be ready in the same folder with name classes_dex2jar.jar.

Hope this helps you and All reading this... :)

If anyone is still looking for an easy way to decompile an APK (with resource decompiling), have a look at the tools I have created: https://github.com/dirkvranckaert/AndroidDecompiler

Just checkout the project locally and run the script as documented and you'll get all the resources and sources decompiled.
