Android Socket简单封装

公司资源库中会与 C# 程序通讯，和同事商讨了之后决定用使用 Socket 通讯方式，则此处简单的封装了一个相关库

代码部分相对于比较简单，使用也比较方便，使用方法如下：

SocketClient socketClient = SocketClient.getInstance();//初始化连接
socketClient.creatConnect(ip, port);//创建连接
socketClient.setOnConnectListener(linstener);//创建监听
socketClient.send(s);//发送数据
socketClient.disconnect();//关闭连接
