大致就是
Device side:
install SSH Server, add ssh server on 22222 port and user q
start ssh server
PC side:
adb forward tcp:22222 tcp:22222 //这是为了能够从PC访问android里的ssh server的22222端口。
ssh -f -N -R 3000:localhost:3000 q@localhost -p 22222
Then you can use port 3000 in device,
it will be forwarded to PC‘s 3000 port
从Android访问PC端的port (reverse port forwarding)
