本文主要向大家介绍了C/C++知识点之利用Xposed破解程序，通过具体的内容向大家展示，希望对大家学习C/C++知识点有所帮助。

运行程序

开始分析

包名
com.bluelesson.crackme002

类名
com.bluelesson.crackme002.MainActivity

函数名称以及参数类型
boolean CheckRegister(String paramString1, String paramString2)

开始编写代码
Main源码

package com.example.liuhailong.hook;import android.telephony.TelephonyManager;import de.robv.android.xposed.IXposedHookLoadPackage;import de.robv.android.xposed.XC_MethodHook;import de.robv.android.xposed.XC_MethodReplacement;import de.robv.android.xposed.XposedBridge;import de.robv.android.xposed.XposedHelpers;import de.robv.android.xposed.callbacks.XC_LoadPackage;public class Main implements IXposedHookLoadPackage {    @Override    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {        //先判断要 hook的包也就是那个 app        if(!loadPackageParam.packageName.equals(""com.bluelesson.crackme002"")){            //打印日志这个打印在 apk上
            XposedBridge.log(loadPackageParam.packageName);            return;
        }        //打到对应的方法 进行替换 replaceHookedMethod替换方法        //参数1：名称 参数2：方法名 参数3：实现监听 重写方法
        String classname=""com.bluelesson.crackme002.MainActivity"";
        XposedHelpers.findAndHookMethod(
                 classname,
                loadPackageParam.classLoader,                ""CheckRegister"",
                String.class, String.class,                new XC_MethodHook() {                    @Override                    protected void beforeHookedMethod(MethodHookParam param) throws Throwable {                        super.beforeHookedMethod(param);                        //打印参数
                        XposedBridge.log(""hook 的参数1：""+param.args[0]);
                        XposedBridge.log(""hook 的参数2：""+param.args[1]);
                    }                    @Override                    protected void afterHookedMethod(MethodHookParam param) throws Throwable {                        super.afterHookedMethod(param);                        //设置调用之后的返回值
                        param.setResult(true);
                    }
                }
        );
    }
}

记得重启
运行
