Reverse Android: Some miscellaneous Android reverse-engineering tools.

This repository contains some tools I've written for reverse-engineering Android applications, as well as any that I may write in the future.

You can find the initial announcement of these tools on my blog: http://blog.nelhage.com/2010/12/some-android-reverse-engineering-tools/

The contents so far are:

• ddx.el: An emacs mode for working with Android assembly. Includes two related modes, ddx-mode and smali-mode, for working with the output of Dedexer (http://dedexer.sourceforge.net/) and baksmali (http://code.google.com/p/smali/). The mode was written for reading decompiled assembly, but may also be useful for people writing smali assembly.

• ddx2dot: A Python script for rendering methods in dedexer-produced assembly files to control-flow graphs using dot (http://www.graphviz.org/).

  Usage is 'ddx2dot FILE.ddx METHOD-NAME OUT-FILE'

  METHOD-NAME should be a prefix of the fully type-qualified name of the desired method. The output format will be detected from the extension on OUT-FILE; If auto-detection fails, the program will write dot source code.

  Sample output can be seen at http://blog.nelhage.com/wp-content/uploads/2010/12/parseToken.png

  Currently it only supports rendering a single method at a time. If there's interest in rendering an entire class to a giant image, I might implement that.
