# JarHook
An example about hooking a Jar.
[中文](https://github.com/BruceWind/JarHook/blob/master/README_zh.md)
### my goal
In this project, I put `MainActivity.hookXM(String name);` into `sayHello`.
the source code of this jar in hello sub-module ：
``` java
package com.androidyuan;
public class Hello {
public Hello() {
}
public static void sayHello(String name) { //this method would be hooked.
}
}
```
### important code in build.gradle
```
['methodName': 'sayHello', 'methodDesc': '(Ljava/lang/String;)V'
```
This code above has the structure is Byte-code. If you have seen some byte-code example, you may be familiar with it.
### Priciple
It modify Byte-code by hibeaber, which work with gradle and building process. And it depend on ASM.
