BudHook

BudHook add a similar Xposed api to YAHFA.<br> BudHook based on several projects below:

• YAHFA
• asmdex
• TurboDex

What did it solved

When using YAHFA, every hook of a method, you have to write a method to replace it, if you want to call the original method, you must write another method to save the original method information. This is very troublesome to use. BudHook generates these methods dynamically. It is very simple to use.

How it works

When hooking a method, budhook will generate the two methods based on the information of the hooked method automatically, then generate the dex file, and finally load the dex file to complete the hook.

How to run this demo

• 1.Import the project in Android Studio (with Instant Run disabled).
• 2.Build appplugin and then put appplugin-debug.apk into sdcard.
• 3.Run app.

Support

Budhook adds a layer written in java for YAHFA,so BudHook supports what YAHFA support.<br> Android 5.0 - 8.1. <br> ABI arm64-v8a,armeabi-v7a,x86.

API

It is recommended to run and read this demo first. There are several important classes :

• BudHelpers: High-level API for convenient hook.Like XposedHelper.
• BudBridge: Export two core functions for hook: hookMethod,hookManyMethod.
• BudCallBack: Provide beforeCall and afterCall for subclass overrides.Like XC_MethodHook
• BudCallBack.MethodHookParams: Wraps information about the method call and allows to influence it.Basic types will be boxed or unboxed automatically.setResult function will prevents the call to the original method.

Note

• TurboDex is useful to avoid some problem that caused by optimization.
• Notice the capacity initialized of YAHFA.
• Get a Context when BudHook initialized only to get a ClassLoader and a place to write and read Dex file,change the source as you like.
• Pay attention to your ClassLoader, otherwise it may cause some reflection problems.
