Developing games for mobile devices is certainly one of the most lucrative genres today. Google reflected this importance by splitting the "Games" section of the Play Store into sub-catogries to account for the growing market in that area. With Android TV Google even created a whole platform designed for gaming on Android and partners like Nvidia and Razer are joining the party.
It's already hard enough to come up with a fresh idea for a new game, make it look good and work on all the target devices. But adding social features like leaderboards, achievements, multiplayer features to compete with friends and offering an easy way to continue a game phone that you started on your tablet is what can catapult a good app to a great one everyone knows. All these features and more you can get with the Google Play Games Services bringing you happier users, higher rentention rates and viral recommendations - all for free and with support for all major platforms.
The talk will walk you through the different parts of Google Play Games Services, how to set them up and integrate them with your Android app, mention a few pitfalls and finishes off with a multiplayer live demo of these features - if the demo gods are playing nice. In the end you'll be ready to easily add those features to your app and make your users happy while still having time to focus on what's important: Your game.
