服务器端编程

Question

I'm looking to program something for an Android machine. Basically I want the phone to communicate with a server, sending it TCP/UDP packets, and I want the server to reply to the phone an answer depending on the packet received.

I did it while ago, with 2 PC's it wasn't really a problem. I had my "server side" running on a loop listening to a certain port and then replying.

My question is how should I write this code if I don't want to have a PC running as a server? Any recommendations on a good free-host-server on the web, and what kind of language I should use..?

As you can see I'm a bit lost, and need some tips/guides or anything that will help me get started.

Thanks a lot

Answer 1

Since you want to go from a server on the web to an android device there are a large number of choices. Just as a starting point I'd look into Google App Engine as your server (Free for light traffic) and Android development. If you search for those two keywords (GoogleAppEngine & Android) I bet you find many tutorials that will get you started.

PS: Your first paragraph describes every single web application ever created--in fact it would make a reasonable definition of what a "Server Application" is--so I'd say it's somewhat general but I hope I got the idea of what you were after and gave you a push in the right direction.

Without better understanding of the problem space in play, he says:

Honestly, you're better off just writing a web service the phone can contact via HTTP. All of the APIs are already there in both Android and whatever server side technology you want to use (Java, Python, Ruby, knock yourself out).

Writing a bespoke socket connector is pretty archaic... 1990 called, they want their proprietary socket protocol back...
