Making and hosting a mulitplayer android game

Hello pals. I need some helps to help me plan a game (Android). How can can a team deploy an android multiplayer game?

  • the game is similar to the “critical Ops” and “modern combat 5” android game, how should we plan for it?
  • What should we consider based on the network and server side?
  • What should we avoid during coding and hosting? its our first game.
  • What servers are available for hosting android games?
