I'm making a game for android but I'm having trouble putting together an online leader board system for it. It'd be great if I'm able to integrate Google Play Games leader boards but I unable to find any clear instructions on how to do so.
Any other method to create functional leader boards that you can give is also acceptable. I just need to be able to retrieve the list of scores in order to compare it to the player's score, be able to update the list of high scores with the player's score and display the top scores.
