【安卓】开发跳过广告app，具备“李跳跳”app的部分功能

前言

现在手机的开屏广告还是挺多的，还有应用内弹出广告，青少年模式等，市面上很多跳过广告app下架了，我利用工作闲暇时间开发了自己用的app，不传播，分享知识！

实现思路

利用手机的无障碍服务，该服务可以监听屏幕窗口的layout树，通过遍历窗口的View，检测到包含“跳过”、“关闭”等按钮，执行自动化点击事件，大部分跳过广告的原理都是这样的，根据弹窗规则匹配的JSON文件里面定义的上百种APP的弹窗规则，可以跳过大部分弹窗。

代码结构

包括两个读取规则实体类，一个无障碍服务类，一个Activity类和一个规则JSON文件。

主要代码

一、activity类
