Android端通过Usb建立Socket通讯（实时发送视频数据）

1.创建出 ServerSocket

serverSocket = new ServerSocket(端口10086);

2.adnroid端保持等待客户端等待连接状态

    Socket accept = serverSocket.accept();

3.添加网络请求权限

  <uses-permission android:name="android.permission.INTERNET" />

4.使用ADB命令端口映射 转端口

adb forward tcp:12580 tcp:10086

例：adb forward tcp:PC端连接的端口（12580） tcp:Android写的端口（10086）

5.pc端建立客户端连接
客户端连接的IP是127.0.0.1(就是本地IP)，端口是：映射后的端口-以上面为例（12580）

            //推荐一个好用的调试工具 SocketTools
