[android-developers] Re: A very strange ServerSocket.accept problem

Can you please show some more information from the log cat..
and at the same time need to see the client code where it gets
connected to the server port.

I think it is sucefully creating the server socket, the problem seems
with the client and where client is not polling to the server port.

Thanks,
Arjun.
