Android Question HTTP Server


Licensed User
I would like to learn how to send information from multiple devices and collect the information at a central point. Say a contest between 10 devices and the stats are collected and standings returned to the devices. Since WIFI can be lost the information should be sent and received at various times.

I was researching WIFI to a host device but I saw Erel suggest HTTPServer over WIFI. He mentions HTTP Server tutorial but I have yet to find a tutorial.

Any suggestions or recommendations for the path? If HTTP server is the best way where can I learn about all I will need to do.
