How can i create score Windows like this ?
ok, now i understand what you want: it's a leaderboard! - For that you have to use the leaderboard API from google play service; you have also to create an account on android developer console (you have to pay for that, i cannot tell you how much it is for now) then you add your leaderboard to your game (which needs to be published)

İs there any example about it? @akenaton
