Android Question Game. What technic and how?

[ValhallSW]

I want make a game, where one person (device) asks a question, and others answers. And the first person who answers correct gets the point, and a message goes to the first person telling who got the point.

1. Is it best to organize each devices addresses on a server (everyone needs to log in first)?
2. To send messages back and forth, is it best to use push notifications (GCM), or...??? and how. I have tried to read about it, but I do not understqnd how it works.
3. It will of course cover both platforms iOS and Android (Windows Phone will have to wait).

If someone have any suggestions, I will be very thankfull.

I guess that they need to be connected over the internet, right?

It is a good fit for WebSockets with B4J server. See the online chat example: https://b4x.com:51041/chat/index.html

It works with browsers, but you create native clients instead.

I am having a bit of a problem following the code.

Are there any tutorials about this? Preferably video-tutorial.
