my goal

In this project, I put MainActivity.hookXM(String name); into sayHello.

the source code of this jar in hello sub-module ：

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'
