AndroidAsync 是一个基于nio的异步socket ，http(客户端服务器端)，websocket，socket.io库，AndroidAsync 是一个底层的网络协议库，如果你想要一个容易使用，高级的，http请求库，请使用Ion(它是基于AndroidAsync 的)，正常来说开发者更倾向于使用 Ion。
如果你需要一个未被封装的Android的raw Socket， HTTP client/server, WebSocket, and Socket.IO， AndroidAsync 正适合你。
特性
基于NIO，一个线程，回调驱动，高效
所有的操作返回一个Future，而且可以取消
All operations return a Future that can be cancelled
Socket client + socket server
HTTP client + server
WebSocket client + server
Socket.IO 客户端
