Xposed hook Acitivity并获取Intent参数信息

Xposed hook acitivity并获取Intent参数信息

本篇文章主要讲述下使用Xposed hook activity 的oncreate 方法,从而获取到activity 对象,来打印输出intent 的相关内容.

1: hook onCreate()

代码如下:打印activity.

        XposedHelpers.findAndHookMethod(Activity.class, "onCreate", Bundle.class, new XC_MethodHook() {@Overrideprotected void afterHookedMethod(MethodHookParam param) throws Throwable {Activity activity = (Activity) param.thisObject;String activityName = activity.getClass().getName();Log.d("IntentHook", "Activity created: " + activityName);}});

2: 打印intent参数

具体的代码如下:

package com.zh.xpose;import android.annotation.TargetApi;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.util.ArrayMap;
import android.util.Log;import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.util.function.BiConsumer;import static com.zh.xpose.HookModule.TAG;/*** @Author: zh* @Time: 23-12-6.* @Email: * @Describe:*/
public class Utils {public static Method getDeclaredMethod(Class<?> cls, String methodName, Class<?>... parameterTypes) {while(true) {try {if (cls != Object.class) {try {Method m = cls.getDeclaredMethod(methodName, parameterTypes);if (!m.isAccessible()) {m.setAccessible(true);}return m;} catch (Throwable throwable) {cls = cls.getSuperclass();continue;}}} catch (Throwable throwable) {Log.e(TAG, "getDeclaredMethod: ",throwable );}return null;}}@TargetApi(Build.VERSION_CODES.N)public static void printIntentExtras(Intent i, final String tag) {try {if (null != i.getExtras()) {Bundle extras = i.getExtras();Method getMapMtd = getDeclaredMethod(Bundle.class, "getMap");ArrayMap<String, Object> mapList;if (null != getMapMtd) {mapList = (ArrayMap<String, Object>) getMapMtd.invoke(extras);} else {mapList = (ArrayMap<String, Object>)getFieldValue(extras.getClass(),extras, "mMap");}if (null != mapList) {mapList.forEach(new BiConsumer<String, Object>() {@Overridepublic void accept(String s, Object o) {Log.d(tag, "ams: intent extra " + s + " = " + o);if (o instanceof Intent) {printIntentExtras((Intent) o, tag);}}});}}} catch (Throwable e) {e.printStackTrace();}}public static Object getFieldValue(Class<?> cls, Object org, String name) {try {Field f = getDeclaredField(cls, name);if (null != f) {return f.get(org);}} catch (Throwable throwable) {Log.e(TAG, "getFieldValue: ", throwable);}return null;}public static Field getDeclaredField(Class<?> cls, String fieldName) {if (null != cls) {while (cls != Object.class) {try {Field f = cls.getDeclaredField(fieldName);if (!f.isAccessible()) {f.setAccessible(true);}return f;} catch (Throwable var3) {cls = cls.getSuperclass();}}}return null;}}

运行可已看到输出如下:
