Disassemble dex files

Android SDK comes with the tool dexdump.exe

To disassemble a dex file just use the following command:

dexdump.exe -d -f -h classes.dex >dexdump.txt

The output will be stored in the file dexdump.txt, and the format is dalvik bytecode, not java bytecode.

I will investigate how to modify this file.


  1. So your investigation makes results ?

  2. Hi,

    I did some tools but they are not very reliable. If you are interested you can try the tool UnDX, search it in google, it's a cool tool to convert dex files to java classes.
