XAppDebug

Debug any application of your choice!

In recent version of Android (starting from... Nougat or Oreo I guess?), un-debuggable apps won't show its name in the logcat view of Android Studio.

This is somehow inconvenient since at some point we always have to build our apps with release configuration, which disables the debuggable flag and making life difficult.

This xposed module allows you to toggle debuggable for any app you want.

Features

  • Reasonable UI
  • Hooks both Process.start() and PackageManagerService.getPackageInfo().
  • Works with multi-user

How it works?

This module inject hooks to the android system package, and tricks the system think another package is build with debuggable option.

Usage

  1. Enable XAppDebug (this module) in your xposed framework settings app
  2. Hook the android system package if any varient of "application scope" is enabled. DO NOT HOOK THE INDIVIDUAL PACKAGE YOU WANT TO DEBUG
  3. Launch XAppDebug UI, select the app you want to debug
  4. kill and restart the victim app
  5. Enjoy!

Notes

  1. For users with EdXposed or LSPosed using "application scope", attach this module to android system package.
  2. For users with Work profile, install this all in both your Main profile and Work profile. Attach to android package in your Main profile, and tick the apps you want to debug in the according profile.

Special Thanks

I've tried several Xposed modules, but they either don't work with multi-user (work profile) or is too old to even work correctly.

That's why I started this project. However, lots of codes are copied from refactored out of these projects.

  • XDebuggable:
    • Works the best IMHO
    • Hooks Process.start()
    • Can only enable one app because it utilize the debug options in "Developer Options" from System.UI.
  • XDebug:
    • Works, no UI.
    • Hooks Process.start()
    • Making EVERY app debuggable
  • App Debuggable:
    • Good UI
    • Hooks PackageManagerService.getPackageInfo()
    • Writes file to /sdcard and /data (which is IMHO dirty)
    • No multi-user support (because of ↑↑↑)
    • Requests LOTS of unnecessary permissions (even wants SU...!!)
  • OpenDbg:
    • Good UI, too.
    • Hooks PackageManagerService.getPackageInfo()
    • Pollute /sdcard
