安卓基于HttpURLConnection网络请求
实现GET请求及其POST请求，加入线程队列多线程时访问不崩溃。
加入取消线程队列，如页面跳转。
支持安卓6.0
在Handler里面实现回调，更改UI界面不崩溃。

两个参数为GET请求，三个参数为POST请求。
GET请求用法举例:

            String url = "http://www.baidu.com";            Ynet.add(url, new YnetListener() {                @Override                public void response(boolean isSuccess, String url,String value, Map<String, Object> parameter) {                    if (isSuccess) {                        Log.e("请求成功", value);                    } else {                        Log.e("网络连接失败", value);                    }                }            });

POST用法举例：

            String url = "http://www.baidu.com";            HashMap<String, Object> map = new HashMap<String, Object>();            map.put("user", "yujing");            Ynet.add(url, map,new YnetListener() {                @Override                public void response(boolean isSuccess, String url,String value, Map<String, Object> parameter) {                    if (isSuccess) {                        Log.e("请求成功", value);                    } else {                        Log.e("网络连接失败", value);                    }                }            });

是不是简单且方便。当网络请求失败value就是失败原因说明。比如超时，比如状态码为404。
