Hi James,
Thanks a lot! I actually just figured it out as well and was about to
post my solution here.
http://developer.android.com/guide/developing/tools/emulator.html#emulatornetworking
So for anyone having a similar problem,
Basically 10.0.2.2 is the Android Emulator's alias to 127.0.0.1
The emulator does not understand when you specify "localhost"
So change the line:
Socket socket = new Socket("localhost", 5554);
to
Socket socket = new Socket("10.0.2.2", 5554);
Cheers!
