How to implement a real time bidirectional connection with server in android
<p>I have experience developing in android and using REST services, but now I'd like to implement an online game for android. For example a tic-tac-toe for multiplayer, where a user can invite to other to play a game and each one receive the actions of the other in real time.</p>

<p>Using REST for this kind of apps would require constants surveys to the server for updates and its a bad idea.Isn't it?</p>

<p>My question is what are the typical aproaches for this kind of "permanent" connections. I just need some hints about the technologies and protocols in client and server for start searching and read :D</p>

<p>Thanks</p>
