Xposed hook acitivity并获取对应的参数等信息

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() {
            @Override
            protected 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;

    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>() {
                        @Override
                        public 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:
