XPosed实践

项目配置

官方教程
首先清单文件

<meta-data
            android:name="xposedmodule"
            android:value="true" />
        <meta-data
            android:name="xposeddescription"
            android:value="test_xposed" />
        <meta-data
            android:name="xposedminversion"
            android:value="82" />

添加app下依赖

compileOnly 'de.robv.android.xposed:api:82'

在main目录下建立assets资源文件夹

目录结构

XposedInit里写hook逻辑，XposedBridge.log的日志在XPosed Installer的日志里看

public class XposedInit implements IXposedHookLoadPackage {
    @Override
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
        XposedBridge.log("========test");
        if(lpparam.packageName.equals("com.example.xposed")){
            XposedHelpers.findAndHookMethod("com.example.xposed.MainActivity", lpparam.classLoader, "onCreate", Bundle.class, new XC_MethodHook() {
                @Override
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    super.beforeHookedMethod(param);
                    XposedBridge.log("beforeHookedMethod");
                }
                @Override
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    super.afterHookedMethod(param);
                    XposedBridge.log("========afterHookedMethod");
                    Class<?> aClass = lpparam.classLoader.loadClass("com.example.xposed.MainActivity");
                    Field textView = aClass.getDeclaredField("textView");
                    textView.setAccessible(true);
                    TextView tv = (TextView) textView.get(param.thisObject);
                    tv.setText("success");
                }
            });
        }
    }
}

下载XPosed Installer

root的手机直接下载Xposed Installer，由于Android 5.0以上采用ART，而5.0以下默认采用Dalvik， 所以是有两个版本的Xposed，附上下载链接： Android 4.0.3-4.4：repo.xposed.info/module/de.r… Android 5.0以上：：forum.xda-developers.com/showthread.…

未root下载太极或者virtualPosed

长按桌面会出现添加项目和设置，此时先添加项目

桌面
桌面上滑进入首页

点击左上角，打开模块勾选自己编写的hook项目

模块

此时回到桌面点击设置，然后点击重启

设置

现在进入首页点击hook项目就可了

hook前
hook后

其它一些API

替换方法，跳转到其它activity

XposedHelpers.findAndHookMethod("me.suncloud.marrymemo.view.SplashActivity", lpparam.classLoader, "onLaunchFinish", new XC_MethodReplacement() {
                @Override
                protected Object replaceHookedMethod(MethodHookParam param) throws Throwable {
                    XposedBridge.log("replaceHookedMethod");
                    Class<?> aClass = XposedHelpers.findClass("com.hlj.hljmvlibrary.activities.WeddingMvListVideoActivity", lpparam.classLoader);
                    ((Activity)param.thisObject).startActivity(new Intent((Activity)param.thisObject, aClass));
                    ((Activity)param.thisObject).finish();
                    return null;
                }
            });

修改方法返回值

XposedHelpers.findAndHookMethod("com.hunliji.hljtinker.utils.Utils", lpparam.classLoader, "isXposedExists", Throwable.class, new XC_MethodHook() {
                @Override
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    super.beforeHookedMethod(param);
                }

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

fastjson打印Object

String className = "com.hlj.hljmvlibrary.activities.VideoMakeActivity";
            Class<?> mvMakeClass = XposedHelpers.findClass("com.hlj.hljmvlibrary.models.MvVideoMakeBean", lpparam.classLoader);

            XposedHelpers.findAndHookMethod(className, lpparam.classLoader, "setData", mvMakeClass, new XC_MethodHook() {
                @Override
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                    Field movieId = param.thisObject.getClass().getDeclaredField("movieId");
                    Field mouldId = param.thisObject.getClass().getDeclaredField("mouldId");
                    movieId.setAccessible(true);
                    mouldId.setAccessible(true);
                    XposedBridge.log("========movieId===" + movieId.get(param.thisObject).toString());
                    XposedBridge.log("========mouldId===" + mouldId.get(param.thisObject).toString());
                    super.beforeHookedMethod(param);
                    for (Object arg : param.args) {
                        Object toJSON = JSON.toJSON(arg);
                        XposedBridge.log("========args===" + toJSON.toString());
                    }
                }

                @Override
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    super.afterHookedMethod(param);
                    XposedBridge.log("========afterHookedMethod");

                }
            });
