PC与Android设备通过USB建立通信连接

通过adb的adb forward指令可以方便的通过USB连接建立PC端与Android的连接。
1. Android设备通过USB连接到计算机上，android手机打开开发者选项；
2. 确保手机连接到计算机的情况下，计算机上运行adb forward tcp:8000 tcp:9000，将PC端8000端口的数据, 转发到Android端的9000端口上；
3. Android设备上编写APP，作为网络通信的Server端，建立ServerSocket，打开端口9000；
4. PC机上编写程序，作为网络通信的Client端，打开端口8000；
5. PC端与Android端即可建立Socket连接进行数据通信。
