上一篇说了 ios 的开屏广告，这次把 Android 的也发下。逻辑，界面和 ios一致。
需求：广告不是一成不变，要随时更换图片，上下架时间，以及要启动就展示，需要先存到本地，以及点击跳转等问题。
服务端返回的数据格式
adver = (

endtime = 1516622424;
id = 7;
link = "https://www.baidu.com";
pic = "/uploads/image/18/01/5a65608db3ebb.png";
}
);

//有广告字段
JSONObject adJsonObj = data.getJSONArray("adver").getJSONObject(0);

String pic = adJsonObj.getString("pic");
String link = adJsonObj.optString("link");

这段 android 是我之前同事写的，个人感觉写的烂透了，时间容许我会给重构成 demo。先这样吧。。
