xposed是什么: 必须部署在ROOT后的安卓手机上，通过替换/system/bin/app_process程序控制zygote进程，使得app_process在启动过程中会加载XposedBridge.jar这个jar包，从而完成对zygote进程及其创建的dalvik虚拟机的劫持。

AS 开发xposed模块步骤(java sdk等环境配置略):

一、创建Empty Activity工程

选择好之后点击Finish

二、修改app/src/main/AndroidManifest.xml信息

AS以project模式显示，在如图所示加入红色框选中信息：

        <!-- 告诉这个模块是xposed模块-->
        <meta-data
            android:name="xposedmodule"
            android:value="true" />
        <!-- 该模块的描述信息-->
        <meta-data
            android:name="xposeddescription"
            android:value="这是hook ks的sig" />

        <!-- 该模块最低支持的版本-->
        <meta-data
            android:name="xposedminversion"
            android:value="44" />

如需修改模块名称: 以android模式显示，修改res/values/strings.xml中app_name属性。

三、修改app/build.gradle(配置XposedBridgeApi-xx.jar)，用于从jcenter仓库拉取 de.robv.android.xposed:api:82 这个API

在build.gradle加入以下代码，点击右上角Sync Now(如网络不通，手动下载XposedBridgeApi-82.jar ，拖放到“项目名称/app/libs/”里面，然后右键“Add As Library” 自行添加这个jar包。而compileOnly ‘de.robv.android.xposed:api:82′和 compileOnly ‘de.robv.android.xposed:api:82:sources’这两句仍然照常添加。)

四、编写demo测试

在MainActivity.java中加入如下代码:

package com.example.xp;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private Button button;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, toastMessage(), Toast.LENGTH_SHORT).show();
            }
        });
    }

    public String toastMessage() {
        return "Hello World!";
    }
}
1234567891011121314151617181920212223242526272829

在app\src\main\res\layout\activity_main.xml中加入如下代码:

	<Button
        android:id="@+id/button"
        android:layout_width="110dp"
        android:layout_height="50dp"
        android:layout_marginStart="141dp"
        android:layout_marginTop="88dp"
        android:layout_marginEnd="160dp"
        android:text="Button"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
1234567891011

在MainActivity统计目录下创建Test.java，写入如下代码:

package com.example.xp;

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 Test implements IXposedHookLoadPackage {
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {

        if (loadPackageParam.packageName.equals("com.example.xp")) {

            XposedBridge.log(" hook到了!");

            Class clazz = loadPackageParam.classLoader.loadClass("com.example.xp.MainActivity");

            XposedHelpers.findAndHookMethod(clazz, "toastMessage", new XC_MethodHook() {

                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    super.beforeHookedMethod(param);
                }

                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    param.setResult("已经hook成功!");
                }
            });
        }
    }
}
