Apps Multiplayer games: Client-Server Architecture & MySqlServer

[rick_mo]

I have just started developing an online android game (X's and O's). And, I want to create a connection between two players via a Client-Server model. However, I have no idea how to start. Can you guide me through this?

I use WAMPServer and AndroidStudio. I've already created a database on PHPMyAdmin.

Thank you.
