Android app with facebook integration

I would like to make a android app where people can play a game with each other. People have to sign in with facebook or with there email-address (additional more options like mobile number, etc.) and make a unique nickname. Then a start screen has to come. People can choose a player from there facebook friends, search a random opponent or search a player-name (like start-screen of wordfeud). The game: The game is like Dots and Boxes and can only be played with 2 players. Starting with an empty grid of dots, players take turns, adding a single horizontal or vertical line between two unjoined adjacent dots. A player who completes the fourth side of a 1×1 box earns one point and takes another turn. (The points are typically recorded by placing in the box an identifying mark of the player, such as an initial or color). The game ends when no more lines can be placed. The winner of the game is the player with the most points. The board may be of any size. The outer border already has lines.

It is for the first part, if it works clearly, maybe some additional projects will come.
