This is a Decompiler that extracts the source code of an Android application (including XML files and image assets). Works directly from your android device.


  • Select either CFR 0.110, JaDX 0.6.1 or FernFlower (analytical decompiler) to use as the decompiler (more to come).
  • Runs directly on an android device (4.x and above).
  • Select apk from sdcard (or) from a list of installed applications.
  • Easy to use.
  • Decompiles resources too (layouts, Drawables, Menus, AndroidManifest, image assets).
  • Displays code in a clean-syntax-highlighted form.
  • The decompiled source can easily be copied from the sdcard (source is stored in ShowJava folder in the sdcard).
  • Simple source browser with a summary of all decompilation errors.
  • Each decompiled source file has commented references to classes that could not be decompiled.
  • Share the decompiled source easily with the built in archive + share mechanism.

Known Issues

  1. Does not work with system applications in most of the phones (especially ones that are not de-odexed).
  2. Slow on phones with single core processors.
