如何使用xposed来钩住函数？

Question

例如，我反编译应用程序，想用xposed来钩子函数，我该怎么做呢？

package com.my.app;
public class myClass 
{
public static int myFunction() 
   {
      //do something inside
   }   
}

如何将"myFunction“与xposed挂钩？

Answer 1

您是否尝试过简单地根据您的类和方法调整可用的示例？

XposedHelpers.findAndHookMethod("com.my.app.myClass", lpparam.classLoader, "myFunction", new XC_MethodHook() {
    @Override
    protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
        XposedBridge.log("before myFunction()");
    }
    @Override
    protected void afterHookedMethod(MethodHookParam param) throws Throwable {
        XposedBridge.log("after myFunction()");
    }
);
