        公司想花最少的开发成本，将现有的移动H5 页面封装成APK，虽然现在这种封装平台也很多，也很方便，但没能精细到自己想要的一些细节，毕竟H5和封装后的APK 有些展示 还有一些差异。

        混合开发想解决如下问题：

            1.按其它APP的国际惯例，开屏广告位。

            2.按APP支付处理方式直接跳转相应支付应用。

            3.对应的联系方式快捷跳转相应应用场景（点QQ进入QQ对话框，电话直接发起拨号，分享直接进入朋友圈等）。

            4.url地址过滤，针对某些地址，为了使用体验跳转到系统浏览器。

            5.版本更新迭代。

            6.APP访问请求头追加信息描述，服务器能做出相应不同的展示。

            7.APP通过注入JS动态动对H5页面做一些智能化场景（自动登陆，智能填写补充，智能提示..）。

        如果想要更精细，都是可以实现，比如消息推送，悬浮导航等。
