正文

使用exposed 遇到了一些坑，这里记录一下

源码：

package com.example.exposedlesson01;

import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodHook;
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 lpparam) throws Throwable {
        String t_packageName = lpparam.packageName;
        if ("hfdcxy.com.myapplication".equals(t_packageName)) {
            XposedBridge.log("hooked!!!");
            Class<?> aClass = lpparam.classLoader.loadClass("hfdcxy.com.myapplication.MainActivity");

            XposedHelpers.findAndHookMethod(aClass, "check", String.class, String.class, new XC_MethodHook() {
                @Override
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    super.beforeHookedMethod(param);
                    // origin args
                    String name = (String)param.args[0];
                    String password = (String)param.args[1];
                    XposedBridge.log("hooked!!! name: " + name);
                    XposedBridge.log("hooked!!! password: " + password);
                    // modify
                    param.args[0] = "hfdcxy";
                    param.args[1] = "1234";
                }

                @Override
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    super.afterHookedMethod(param);
                }
            });

        }
    }
}

坑1（自己没注意）： XposedHelpers.findAndHookMethod，第二个参数是方法名，如果方法有参数，后面要接方法参数类型类

坑2： app 的 build.gradle 不要引入source，只引入api即可，否则不报错，但是永远找不到IXposedHookLoadPackage

dependencies {
	......
    //以下一句引用
    compileOnly 'de.robv.android.xposed:api:82'
}

坑3：jcenter已经过期不提供服务了，一些网上的文档较旧了，改为在setting,gradle中添加

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
		//以下一句引用
        maven { url  "https://api.xposed.info/"}
    }
}

坑4：插件写的有问题，一定要先卸载删除插件，然后重新修改后安装，然后exposed中打开模块并重启手机，；在这里卡了很久，就是因为有时候没这么做，导致一直不成功

最后完美hook
