About

This is basically a Java Decompiler that 'trys' to extract the .java source code from an APK( Android application) and jar files. There are many such decompilers that run on a PC. But, I didn't find one that runs properly on a android phone. So, i thought of making one, and , here it is :D

Features
  1. Runs directly on your android device
  2. Select jar/apk from sdcard (or) from a list of installed applications
  3. Easy to use
  4. Displays code in a clean-syntax-highlighted form
  5. The decompiled source can easily be copied from the sdcard (source is stored in ShowJava folder in the sdcard)
  6. Simple source browser with a summary of all decompilation errors
  7. Each decompiled source file has commented references to classes that could not be decompiled
  8. And more to come ...

What's new in version 1.8 (Version Code: 2)

Huge Additions and Bug-Busting !
  1. Fixed crash on new installations
  2. Fixed crash on devices running on Android Runtime (ART)
  3. Improvements to SSA analysis
  4. Fix precedence issue on instanceof.
  5. improvement to handling some obfuscated switches which caused failure
  6. Minor Bug fixes
  7. Updated CFR to 0.89
  8. Fix precedence issue on instanceof.
  9. Rewrite variable definitions
  10. Better guess for anonymous inner types.
  11. Improvements to implicit cast checking.
  12. Handle empty switches better
  13. Fix bug which could cause some switch-on-enum statements not to be resugared.
  14. And more decompiler improvements

Download (it's free)

Source Code

This will be an Open Sourced project. Put I have some more work to do. And once that's done, I'll release the source code for everyone to benefit from.

Bugs
  1. Does not work with system applications in most of the phones (especially one's that are not de-odexed)
  2. Miscellaneous errors here and there...

Reporting a Bug

Always please attach a logcat while reporting major bugs. You can report bugs via XDA's DevDB Bug Reporting option (or) send me an email at niranjan@leanlab.in

Reasons for Permissions
  1. Internet - Automated bug reporting
  2. External Storage - To store the decompiled source code and to have a working directory for the application
