+使用AgentWeb框架 编写的原生套壳H5项目 实现智慧疫控安卓端原生功能
+基本功能
+
+ * 实现了回退和退出操作
+ * 实现了启动页 轮播图形式启动页 自动轮播等功能
+ 
+ BGABanner-Android 功能效果
+ - [x] 引导界面导航效果
+ - [x] 支持根据服务端返回的数据动态设置广告条的总页数
+ - [x] 支持大于等于1页时的无限循环自动轮播、手指按下暂停轮播、抬起手指开始轮播
+ - [x] 支持自定义指示器位置和广告文案位置
+ - [x] 支持图片指示器和数字指示器
+ - [x] 支持 ViewPager 各种切换动画
+ - [x] 支持选中特定页面
+ - [x] 支持监听 item 点击事件
+ - [x] 加载网络数据时支持占位图设置，避免出现整个广告条空白的情况
+ - [x] 多个 ViewPager 跟随滚动
+
+## 功能 & 库
+1. [`AgentWeb` AgentWeb 是一个基于的 Android WebView ，极度容易使用以及功能强大的库，提供了 Android WebView 一系列的问题解决方案 ，并且轻量和极度灵活](https://github.com/Justson/AgentWeb)
+2. [`BGABanner-Android` 非常好用的轮播图框架,图片采用的是Fresco框架加载](https://github.com/bingoogolapple/BGABanner-Android)
