###前言 最近在研究Android辅助服务,实现了这个小工具,也算是对最近学习的一个总结。

###原理 通过Android 无障碍辅助功能实现模拟点击控件来实现 检查被删好友有两种方法:

  1. 向好友发送一条消息,如果对方已经把你删除,则消息发送失败。
  2. 建群法:新建一个不大于40人的群,如果其中有好友已经把你删除,微信会有条消息提示
  3. 整体执行步骤:启动微信->点击+号->发起群聊->选择35个联系人->点击确定->点击群里详情->删除并退出,依次轮询执行,知道所有好友轮询结束。

本文采用建群的方式进行检查。 本人微信有300好友,全部检测一遍只需3分钟即可,亲测已经成功, 但是建群没有超过40人 会有个别好友会受到打扰消息,可能是微信哪里的bug,具体原因未知。

###说明和app预览 此软件通过无障碍辅助进行模拟点击,无任何外挂木马,无封号风险

###使用方法

  1. Android 手机一部,登录微信账号
  2. 安装辅助软件apk下载地址请点击这里
  3. 打开辅助软件-点击打开辅助功能按钮,跳转到无障碍辅助设置把辅助开关打开。
  4. 点击开始检查按钮,开始一系列的模拟点击,检查完成后会跳转到一个列表会把被删好友列表展示出来。

###实现步骤:

  • 新建Android Studio 工程,新建一个Services类集成AccessibilityService,实现对应方法,详细介绍见代码注释
/**
 * Created by wanglj on 16/10/20.
 */

public class InspectWechatFriendService extends AccessibilityService{


    @Override
    protected void onServiceConnected() {//辅助服务被打开后 执行此方法
        super.onServiceConnected();
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {//监听手机当前窗口状态改变 比如 Activity 跳转,内容变化,按钮点击等事件

    }

    @Override
    public void onInterrupt() {//辅助服务被关闭 执行此方法

    }
}
  • 在manifests.xml文件中注册此服务:
<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.wanglj.inspectwechatfriend"
          xmlns:android="http://schemas.android.com/apk/res/android">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>


        <service
            android:name=".accessibility.InspectWechatFriendService"
            android:enabled="true"
            android:exported="true"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService"/>
            </intent-filter>

            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/inspect_wechat_friend"/>
        </service>

    </application>

</manifest>
  • 新建res/xml/inspect_wechat_friend.xml文件
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
                       android:accessibilityEventTypes="typeWindowStateChanged" 
                       android:accessibilityFeedbackType="feedbackGeneric"
                       android:accessibilityFlags=""
                       android:canRetrieveWindowContent="true"
                       android:notificationTimeout="100"
                       android:description="@string/accessibility"

    />
  • 实现对某个控件的点击

通过getRootInActiveWindow方法获取当前窗口信息,通过findAccessibilityNodeInfosByText方法找到当前对应控件进行模拟点击

public class PerformClickUtils {


    /**
     * 在当前页面查找文字内容并点击
     *
     * @param text
     */
    public static void findTextAndClick(AccessibilityService accessibilityService,String text) {

        AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
        if (accessibilityNodeInfo == null) {
            return;
        }

        List<AccessibilityNodeInfo> nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text);
        if (nodeInfoList != null && !nodeInfoList.isEmpty()) {
            for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {
                if (nodeInfo != null && (text.equals(nodeInfo.getText()) || text.equals(nodeInfo.getContentDescription()))) {
                    performClick(nodeInfo);
                    break;
                }
            }
        }
    }


    /**
     * 检查viewId进行点击
     * 
     * @param accessibilityService
     * @param id
     */
    public static void findViewIdAndClick(AccessibilityService accessibilityService,String id) {

        AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
        if (accessibilityNodeInfo == null) {
            return;
        }

        List<AccessibilityNodeInfo> nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByViewId(id);
        if (nodeInfoList != null && !nodeInfoList.isEmpty()) {
            for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {
                if (nodeInfo != null) {
                    performClick(nodeInfo);
                    break;
                }
            }
        }
    }


    /**
     * 在当前页面查找对话框文字内容并点击
     *
     * @param text1 默认点击text1
     * @param text2
     */
    public static void findDialogAndClick(AccessibilityService accessibilityService,String text1, String text2) {

        AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
        if (accessibilityNodeInfo == null) {
            return;
        }

        List<AccessibilityNodeInfo> dialogWait = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text1);
        List<AccessibilityNodeInfo> dialogConfirm = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text2);
        if (!dialogWait.isEmpty() && !dialogConfirm.isEmpty()) {
            for (AccessibilityNodeInfo nodeInfo : dialogWait) {
                if (nodeInfo != null && text1.equals(nodeInfo.getText())) {
                    performClick(nodeInfo);
                    break;
                }
            }
        }

    }

    //模拟点击事件
    public static void performClick(AccessibilityNodeInfo nodeInfo) {
        if (nodeInfo == null) {
            return;
        }
        if (nodeInfo.isClickable()) {
            nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
        } else {
            performClick(nodeInfo.getParent());
        }
    }

    //模拟返回事件
    public static void performBack(AccessibilityService service) {
        if (service == null) {
            return;
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            service.performGlobalAction(AccessibilityService.GLOBAL_ACTION_BACK);
        }
    }
}
  • 监听窗口事件

获取当前窗口的classname 通过classname进行判断当前手机处于某个界面 下面代码逻辑:

  1. 如果当前为微信主页面,则点击+号然后点击发起群聊
  2. 如果当前页面为创建群聊选择联系人界面,则开启一个while循环模拟滚动时间以及点击选择框,当选择用户到39人时,则模拟点击确定按钮发起群聊。
  3. 发起群聊后,微信会返回哪些用户不是你的好友,这个时候,取到当前控件的字符串并截取用户列表保存到本地。
  4. 获取到不是好友的用户后,点击右上角进入群聊详情,点击删除并退出
  5. 退出后又回到微信主页面,依次执行1 2 3 4步骤,直到滚动到联系人最底部为止。
  6. 当所有用户执行完成后,则启动检查结果界面,列出所有被删好友。

下面为对应逻辑代码:

 @Override
    public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {//监听手机当前窗口状态改变 比如 Activity 跳转,内容变化,按钮点击等事件

        //如果手机当前界面的窗口发送变化
        if (accessibilityEvent.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {

            //获取当前activity的类名:
            String currentWindowActivity = accessibilityEvent.getClassName().toString();
            if(!hasComplete){
                if ("com.tencent.mm.ui.contact.SelectContactUI".equals(currentWindowActivity)) {
                    canChecked = true;
                    createGroup();
                } else if ("com.tencent.mm.ui.chatting.ChattingUI".equals(currentWindowActivity)) {
                    getDeleteFriend();
                } else if ("com.tencent.mm.plugin.chatroom.ui.ChatroomInfoUI".equals(currentWindowActivity)) {
                    deleteGroup();
                }else if("com.tencent.mm.ui.LauncherUI".equals(currentWindowActivity)){
                    PerformClickUtils.findTextAndClick(this,"更多功能按钮");
                    try {
                        Thread.sleep(1000);

###ui automator viewer的使用 uiautomatorviewer可以检查当前手机的布局结构,如果想更精确的找到控件位置,uiautomatorviewer必不可少!

使用方法:

  1. 搭建Android开发环境,并设置环境变量,这里就不说了。
  2. 在Android Studio 中打开 terminal 窗口,或者在终端直接执行命令
$uiautomatorviewer
