Works for me over Wifi...

So the problem is likely your cell operator - either blocking incoming
connections, or else your phone could be behind a NAT.

You also could verify your code by trying it over Wifi.

Hello,

I am attempting to open a ServerSocket on my Android device to receive
network connections, but do not seem to recieve network traffic from
them.

Running netstat -an on the device shows it is listening on
0.0.0.0:1234, but my connections to telnet to <public ip of Android
device>:1234 do not appear (and do not receive a SYN,ACK in response).

How can I write an application which will open an accessible server
socket? Is this possible? I am thinking that either the ISP (mobile
carrier) may be blocking this incoming connection attempts or the
Android OS is blocking them (host firewall) ?

Thanks,
Lee
