The toolset

Reverse engineering Android apps requires a few software tools. Here’s what I used for this project:

  • Android SDKProvides the adb command-line tool, which can pull APKs, data files and settings from the phone.
  • dex2jarConverts Android’s Dalvik executables into JARs, which are easier to reverse engineer.
  • JD, JD-GUIAn excellent Java bytecode decompiler.
  • EclipseA Java IDE to validate discoveries during the reverse engineering process.
