a) Sockets do work and have been tested. However, built-in firewalls will 
prevent you from binding to sockets below 1024. Please supply some example code.

b) This is a python question, not an sl4a question.

server (On the computer)
[code]
import socket
s = socket.socket()
s.bind(("192.168.56.1", 12345))
s.listen(1)
while True:
c, addr = s.accept()
c.send("test")
c.close()
print "done"
[/code]

Client (On android device)
[code]
import android
import socket
d = android.Android()
s = socket.socket()
s.connect(("192.168.56.1", 12345))
print s.recv(1024)
[/code]

Any idea on why this isn't working on my device?

Has there been any advancement in this code?

I found some interesting information today. When I run the following code, it 
prints "True". Hope this will help in some way!

import socket
import android
d = android.Android()
s = socket.socket()
s.connect(("google.com", 80))
print True

It has been tested and found to work, on several platforms.
Unless others can duplicate the problem, I have to assume it is something to do 
with the original poster's network setup.
There is a lengthy thread on this in the discussion list.
If others have problem, please check your desktop firewall settings. Also, 
network settings (some routers implement firewalls of their own.)
