最新版xposed编写教程

环境：
andriod studio2023.1.1
jdk17
gradle8.2

流程：
1.新建项目，选empty views activity即可（其他也可）

2.语言选java，其他路径名称等暗战自己需要随便改，然后点击finish

3.修改AndroidManifest.xml，加入以下代码：

<meta-data
            android:name="xposedmodule"
            android:value="true" />
        <meta-data
            android:name="xposeddescription"
            android:value="xposed" />
        <meta-data
            android:name="xposedminversion"
            android:value="53" />

4.MainActivity修改

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 "没结果";
    }
}

5.在主页面activity_main.xml页面加一个按钮

<Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="别点我，没结果"
        tools:ignore="MissingConstraints"
        tools:layout_editor_absoluteX="132dp"
        tools:layout_editor_absoluteY="286dp" />

6.添加xposed依赖，将api-82.jar文件添加到libs文件夹中

这里要注意一下，直接点击api-82.jar右键，会出现
implementation(files(“libs/api-82.jar”))

我们在build.gradle文件中直接手动改成

compileOnly(files("libs/api-82.jar"))

然后sync一下

7.编写hook文件，添加一个java文件，比如Dain等

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 Dain implements IXposedHookLoadPackage {
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
        if (loadPackageParam.packageName.equals("com.tencent.aaa")) {
            XposedBridge.log(" has Hooked!");
            Class<?> clazz = loadPackageParam.classLoader.loadClass(
                    "com.tencent.aaa.MainActivity");
            XposedHelpers.findAndHookMethod(clazz, "toastMessage", new XC_MethodHook() {
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    super.beforeHookedMethod(param);
                    //XposedBridge.log(" has Hooked!");
                }
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    param.setResult("hooker1.0");
                }
            });
        }
    }
}

8.右键Main文件夹,新建assets

在里面新建xposed_init
里面写hook入口文件

com.tencent.aaa.Dain

然后build，安装到手机，点击按钮，如果出现了hooker1.0，说明配置完成，如果显示没结果，查一下是不是漏掉了哪一步。

至此，一个简单的xposed插件就开发完成了。
