java.net.ConnectException - Connection Refused Android Emulator

Question

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...

According to Emulator Networking IP 10.0.2.2 should be used instead of localhost/127.0.0.1.

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.
