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...

net. ConnectException: Connection refused: 1) First try to ping the destination host, if the host is ping-able it means the client and server machine are in the network. 2) Try connecting to server host and port using telnet.
java.net.ConnectException: Connection refused: connect is one of the most common networking exceptions in Java. This error comes when you are working with client-server architecture and trying to make TCP connection from the client to the server.
net. ConnectException: Connection refused: connect. It's quite possible that either you are providing incorrect host port combination or earlier host port combination has been changed on the server side. Check the latest configuration on both client and server side to avoid connection refused exception.
According to Emulator Networking IP 10.0.2.2 should be used instead of localhost/127.0.0.1.
