问题
I have an android emulator I'm running from eclipse and just trying to connect to a simple socket server I wrote in .NET (c#).
The server is running on the same machine on port 4505. I am able to telnet (through PuTTy) to the server and it works just fine, but when I try to connect to the server with the android emulator I get a: java.net.ConnectException - localhost/127.0.0.1:4505 - Connection refused at org.apache.harmony.luni.net error.
I'm assuming this is because the emulator is on a different subnet or something? If that were the case though I would think I would be getting a different error that would be caught in the UnknownHostException catch block...
回答1:
According to Emulator Networking IP 10.0.2.2 should be used instead of localhost/127.0.0.1.
回答2:
I got this figured out. If I use the internal ip it works fine (192.168.1.%) address.
Sorry for the wasted space here but maybe someone else will be able to use this.
the 127.0.0.1 is for the device (emulator) itself.

instead of 'localhost' put your address (192.168.1.%)
