android----AsyncHttpClient的get,post和图片上传

async-http-client库是一个基于回调函数的Http异步通信客户端Android组件，是在Apache的HttpClient库的基础上开发构建而成的。

Eclipse使用：导入android-async-http-1.4.4.jar 包, 点击下载

AndroidStudio: gradle中引入 compile 'com.loopj.android:android-async-http:1.4.8'

功能特色

利用版4.3.6上游HttpClient代替Android提供defaulthttpclient
兼容AndroidAPI 23高
做异步HTTP请求处理的响应匿名回调
HTTP请求发生UI线程之外
请求使用线程池限制并发资源使用情况
get /后参数生成器（ RequestParams ）
多文件上传没有额外的第三方库
JSON上传流没有额外的图书馆
处理循环和相对重定向
小的开销给你的应用程序只90kb一切
自动智能请求重试次数质量不一的移动连接优化
自动gzip响应解码速度超快的请求支持
二进制协议通信binaryhttpresponsehandler
内置的响应分析JSON与jsonhttpresponsehandler
节能反应直接进入文件fileasynchttpresponsehandler
大的持久性Cookie，保存cookie到你的应用程序的SharedPreferences
杰克逊JSON集成，gson或其他JSON序列化库（德）basejsonhttpresponsehandler
与SAX解析器支持saxasynchttpresponsehandler
语言和内容编码的支持，不仅仅是UTF-8
