Android DisplayPolicy增加一些动作，打开后台接口

---

前言

一些后台接口 界面之类的不方便打开，但是测试需要用到，这里就添加一个10秒内上拉6下，打开一个后台接口界面的

---

一、了解android全局滑动事件的拦截

参考该文章Android10添加 全局左右滑动返回

二、修改

1.DisplayPolicy.java修改

onSwipeFromBottom中发送MSG_OPEN_FACTORY_COUNT 判断次数，同时重置MSG_OPEN_FACTORY_COUNT_REMOVE 的 10S时间，10S内FACTORY_COUNT次数大于6才会打开界面
