 Hi, everyone:
    How can my host machine connect to emulator using socket? In my
application, I need emulator to open a server socket, then host
machine connects to emulator as a client. But when host creates the
socket using "" (xxxxx is the port which emulator is
listenning), it doesn't work. I think maybe the address""
goes wrong. Is it a local address behind the "virtual router" and the
host can't find? If so, how to find a correct IP address of emulator?
