Google Play game services ends year with a bang!

Posted by Benjamin Frenkel, Product Manager, Play Games

In an effort to supercharge our Google Play games services (GPGS) developer tools, we’re introducing the Game services Publishing API, a revamped Unity Plugin, additional enhancements to the C++ SDK, and improved Leaderboard Tamper Protection.

Let’s dig into what’s new for developers:

Publishing API to automate game services configuration

At Google I/O this past June, the pubsite team launched the Google Play Developer Publishing APIs to automate the configuration and publishing of applications to the Play store. Game developers can now also use the Google Play game services Publishing API to automate the configuration and publishing of game services resources, starting with achievements and leaderboards.

For example, if you plan on publishing your game in multiple languages, the game services Publishing API will enable you to pull translation data from spreadsheets, CSVs, or a Content Management System (CMS) and automatically apply those translations to your achievements.

Early adopter Square Enix believes the game services Publishing API will be an indispensable tool to manage global game rollouts:


Achievements are the most used feature in Google Play game services for us. As our games support more languages, achievement management has become increasingly difficult. With the game services Publishing API, we can automate this process, which is really helpful. The game services Publishing API also comes with great samples that we were able to easily customize for our needs

Keisuke Hata, Manager / Technical Director, SQUARE ENIX Co., Ltd.





To get started today, take a look at the developer documentation here.

Updated Unity plugin and Cross-platform C++ SDK

  • Unity plugin Saved Games support: You can now take advantage of the Saved Games feature directly from the Unity plugin, with more storage and greater discoverability through the Play Games app
  • New Unity plugin architecture: We’ve rewritten the plugin on top of our cross-platform C++ SDK to speed up feature development across SDKs and increase our responsiveness to your feedback
  • Improved Unity generated Xcode project setup: You now have a much more robust way to generate Xcode projects integrated with Google Play Game Services in Unity
  • Updated and improved Unity samples: We’ve updated our sample codes to make it easier for first time developers to integrate Google Play games services
  • C++ SDK support for iPhone 6 Plus: You can now take advantage of the out-of-box games services UI (e.g., for leaderboards and achievements) for larger form factor devices, such as the iPhone 6 Plus

We also include some important bug fixes and stability improvements. Check out the release notes for the Unity Plugin and the getting started page for the C++ SDK for more details.

Leaderboard Tamper Protection

Turn on Leaderboard Tamper Protection to automatically hide suspected tampered scores from your leaderboards. To enable tamper protection on an existing leaderboard, go to your leaderboard in the Play developer console and flip the “Leaderboard tamper protection” toggle to on. Tamper protection will be on by default for new leaderboards.Learn more.

To learn more about cleaning up previously submitted suspicious scores refer to the Google Play game services Management APIs documentation or get the web demo console for the Management API directly from github here.

In addition, if you prefer command-line tools, you can use the python-based option here.

Keeping Your Saved Games in the Cloud

Posted by Todd Kerpelman, Developer Advocate

Saved Games Are the Future!

I think most of us have at least one or two games we play obsessively. Me? I'm a Sky Force 2014 guy. But maybe you're into matching colorful objects, battling monsters, or helping avians with their rage management issues. Either way, there's probably some game where you've spent hours upon hours upgrading your squad, reaching higher and higher levels, or unlocking every piece of bonus content in the game.

Now imagine losing all of that progress when you decide to get a new phone. Or reinstall your game. Yikes!

That's why, when Google Play Games launched, one of the very first features we included was the ability for users to save their game to the cloud using a service called the AppState API. For developers who didn't need an entire server-based infrastructure to run their game, but didn't want to lose players when they upgraded their devices, this feature was a real life-saver.

But many developers wanted even more. With AppState, you were limited to 4 slots of 256k of data each, and for some games, this just wasn't enough. So this past year at Google I/O, we launched an entirely new Saved Games feature, powered by Google Drive. This gave you huge amounts of space (up to 3MB per saved game with unlimited save slots), the ability to save a screenshot and metadata with your saved games, and some nice features like showing your player's saved games directly in the Google Play app.

...But AppState is Yesterday's News

Since the introduction of Saved Games, we've seen enough titles happily using the service and heard enough positive feedback from developers that we're convinced that Saved Games is the better offering and the way to go in the future. With that in mind, we've decided to start deprecating the old cloud save system using AppState and are encouraging everybody who's still using it to switch over to the new Saved Games feature (referred to in our libraries as "Snapshots").

What does this mean for you as a game developer?

If you haven't yet added Saved Games to your game, now would be the perfect time! The holidays are coming up and your players are going to start getting new devices over the next couple of months. Wouldn't it be great if they could take your game's progress with them? Unless, I guess, "not retaining users" is part of your business plan.

If you're already using the new Saved Games / Snapshot system, put your feet up and relax. None of these changes affect you. Okay, now put your feet down, and get back to work. You probably have a seasonal update to work on, don't you?

If you're using the old AppState system, you should start migrating your player's data over to the new Saved Games service. Luckily, it's easy to include both systems in the same game, so you should be able to migrate your users' data with their ever knowing. The process would probably work a little something like this:

  • Enable the new Saved Game service for your game by
    • Adding the Drive.SCOPE_APPFOLDER scope to your list of scopes in your GoogleApiClient.
    • Turning on Saved Games for your game in the Google Play Developer Console.
  • Next, when your app tries to load the user's saved game
    • First see if any saved game exists using the new Saved Games service. If there is, go ahead and use it.
    • Otherwise, grab their saved game from the AppState service.
  • When you save the user's game back to the cloud, save it using the new Saved Games service.
  • And that should be it! The next time your user loads up your game, it will find their saved data in the new Saved Games service, and they'll be all set.

In a few months, we will be modifying the old AppState service to be read-only. You'll still be able to read your user's old cloud save games and transfer them to the new Saved Games service, but you'll no longer be able to save games using the old service. We are evaluating early Q2 of 2015 to make this change, which should give you enough time to push your "start using Saved Games" update to the world.

If you want to find out more about Saved Games and how they work, feel free to review our documentation, our sample applications, or our Game On! videos. And we look forward to many more hours of gaming, no matter how many times we switch devices.

Updated Cross-Platform Tools in Google Play Game Services

By Ben Frenkel, Google Play Games team

Game services UIs are now updated for material design, across all of the SDKs.

Game developers, we've updated some of our popular developer tools to give you a consistent set of game services across platforms, a refreshed UI based on material design, and new tools to give you better visibility into what users are doing in your games.

Let’s take a look at the new features.

Real-time Multiplayer in the Play Games cross-platform C++ SDK

To make it easier to build cross-platform games, we’ve added Real-Time Multiplayer (RTMP) to the latest Google Play Games C++ SDK. The addition of RTMP brings the C++ SDK to feature parity with the Play services SDK on Android and the Play Games iOS SDK. Learn more »

Material Design refresh across Android, cross-platform C++, and iOS SDKs

We’ve incorporated material design into the user-interface of the latest Play Games services SDKs for Android, cross-platform C++, and iOS. This gives you a bold, colorful design that’s consistent across all of your games, for all of your users. Learn more »

New quests features and completion statistics

Quests are a popular way to increase player engagement by adding fresh content without updating your game. We’ve added some new features to quests to make them easier to implement and manage.

First, we’ve simplified quests implementations by providing out-of-the-box toasts for “quest accepted” and “quest completed” events. You can invoke these toasts from your game with just a single call, on any platform. This removes the need to create your own custom toasts, though you are still free to do so.

You also have more insight into how your quests are performing through new in-line quest stats in the Developer Console. With these stats, you can better monitor how many people are completing their quests, so you can adjust the criteria to make them easier to achieve, if needed. Learn more »

Last, we’ve eliminated the 24-hour lead-time requirement for publishing and allowing repeating quests to have the same name. You now have the freedom to publish quests whenever you want with whatever name you want.

New quest stats let you see how many users are completing their quests.

Multiplayer game statistics

Now when you add multiplayer support through Google Play game services, you get multiplayer stats for free, without having to implement a custom logging solution. You can simply visit the Developer Console to see how players are using your multiplayer integration and look at trends in overall usage. The new stats are available as tabs under the Engagement section. Learn more »

Multiplayer stats let you see trends in how players are using your app's multiplayer integration.

New game services insights and alerts

We’re continuing to expand the types of alerts we offer the Developer Console to let you know about more types of issues that might be affecting your users' gameplay experiences. You’ll now get an alert when you have a broken implementation of real-time and turn-based multiplayer, and we’ll also notify you if your Achievements and Leaderboard implementations use too many duplicate images. Learn more »

Get Started

You can get started with all of these new features right away. Visit the Google Play game services developer site to download the updated SDKs. For migration details on the Game Services SDK for iOS, see the release notes. You can take a look at the new stats and alerts by visiting the Google Play Developer Console.

New Cross-Platform Tools for Game Developers

By Ben Frenkel, Google Play Games team

There was a lot of excitement at Google I/O around Google Play Games, and today we’re delighted to share that the following tools are now available:

  • Updated Play Games cross-platform C++ SDK
  • Updated Play Games SDK for iOS
  • New game services alerts in the Developer Console

Here's a quick look at the cool new stuff for developers.

Updated Play Games C++ SDK

We've updated the Google Play Games C++ SDK with more cross-platform support for the new services and experiences we announced at I/O. Learn more»

The new C++ SDK now supports all of the following:

Cocos2D-x, a popular game engine, is an early adopter of the Play Games C++ SDK and is bringing the power of Play Games to their developers. Additionally, the Cocos2D-x team created Wagon War, a prototype game showcasing the capabilities of the Cocos2D-x engine with Play Games C++ SDK integration.

Wagon War is also a powerful reference for developers — it gives you immediately usable code samples to accelerate your C++ implementations. You can browse or download the game sources on the Wagon War page on GitHub.

Updated Play Games iOS SDK

The Play Games iOS SDK is now updated with support for Quests and Saved Games, enabling iOS developers to integrate the latest services and experiences with the Objective-C based tool-chains they are already familiar with. Learn more»

The new Play Games SDK for iOS now supports all of the following:

  • Quests and Events. Learn more»
  • Saved Games. Learn more»
  • Game Profile and related Player XP APIs — the SDK now also provides the UI for Game Profile and access to Player XP data for players.

New types of games services alerts

Last, you can now see new types of games services alerts in the Developer Console to learn about issues that might be affecting your users' gameplay experiences. For example, if your app implements Game Gifts, you'll now see an alert when players are unable to send a gift; if your app implements Multiplayer, you'll now see an alert when players are unable to join a match.

Google Play Services 5.0

gps

Google Play services 5.0 is now rolled out to devices worldwide, and it includes a number of features you can use to improve your apps. This release introduces Android wearable services APIs, Dynamic Security Provider and App Indexing, whilst also including updates to the Google Play game services, Cast, Drive, Wallet, Analytics, and Mobile Ads.

Android wearable services

Google Play services 5.0 introduces a set of APIs that make it easier to communicate with your apps running on Android wearables. The APIs provide an automatically synchronized, persistent data store and a low-latency messaging interface that let you sync data, exchange control messages, and transfer assets.

Dynamic security provider

Provides an API that apps can use to easily install a dynamic security provider. The dynamic security provider includes a replacement for the platform's secure networking APIs, which can be updated frequently for rapid delivery of security patches. The current version includes fixes for recent issues identified in OpenSSL.

Google Play game services

Quests are a new set of APIs to run time-based goals for players, and reward them without needing to update the game. To do this, you can send game activity data to the Quests service whenever a player successfully wins a level, kills an alien, or saves a rare black sheep, for example. This tells Quests what’s going on in the game, and you can use that game activity to create new Quests. By running Quests on a regular basis, you can create an unlimited number of new player experiences to drive re-engagement and retention.

Saved games lets you store a player's game progress to the cloud for use across many screen, using a new saved game snapshot API. Along with game progress, you can store a cover image, description and time-played. Players never play level 1 again when they have their progress stored with Google, and they can see where they left off when you attach a cover image and description. Adding cover images and descriptions provides additional context on the player’s progress and helps drive re-engagement through the Play Games app.

App Indexing API

The App Indexing API provides a way for you to notify Google about deep links in your native mobile applications and drive additional user engagement. Integrating with the App Indexing API allows the Google Search app to serve up your app’s history to users as instant Search suggestions, providing fast and easy access to inner pages in your app. The deep links reported using the App Indexing API are also used by Google to index your app’s content and surface them as deep links to Google search result.

Google Cast

The Google Cast SDK now includes media tracks that introduce closed caption support for Chromecast.

Drive

The Google Drive API adds the ability to sort query results, create folders offline, and select any mime type in the file picker by default.

Wallet

Wallet objects from Google take physical objects (like loyalty cards, offers) from your wallet and store them in the cloud. In this release, Wallet adds "Save to Wallet" button support for offers. When a user clicks "Save to Wallet" the offer gets saved and shows up in the user's Google Wallet app. Geo-fenced in-store notifications prompt the user to show and scan digital cards at point-of-sale, driving higher redemption. This also frees the user from having to carry around offers and loyalty cards.

Users can also now use their Google Wallet Balance to pay for Instant Buy transactions by providing split tender support. With split tender, if your Wallet Balance is not sufficient, the payment is split between your Wallet Balance and a credit/debit card in your Google Wallet.

Analytics

Enhanced Ecommerce provides visibility into the full customer journey, adding the ability to measure product impressions, product clicks, viewing product details, adding a product to a shopping cart, initiating the checkout process, internal promotions, transactions, and refunds. Together they help users gain deeper insights into the performance of their business, including how far users progress through the shopping funnel and where they are abandoning in the purchase process. Enhanced Ecommerce also allows users to analyze the effectiveness of their marketing and merchandising efforts, including the impact of internal promotions, coupons, and affiliate marketing programs.

Mobile Ads

Google Mobile Ads are a great way to monetise your apps and you now have access to better in-app purchase ads. We've now added a default implementation for consumable purchases using the Google Play In-app Billing service.

And that’s another release of Google Play services. The updated Google Play services SDK is now available through the Android SDK manager. For details on the APIs, please see New Features in Google Play services 5.0.



Games at Google I/O ’14: Everyone’s Playing Games

By Greg Hartrell, Product Manager, Google Play games

With Google I/O ‘14 here, we see Android and Google Play as a huge opportunity for game developers: 3 in 4 Android users are playing games, and with over one billion active Android users around the world, games are reaching and delighting almost everyone.

At Google, we see a great future where mobile and cloud services bring games to all the screens in your life and connect you with others. Today we announced a number of games related launches and upcoming technologies across Google Play Games, the Android platform and its new form factors.

Google Play Games

At last year’s Google I/O, we announced Google Play Games -- Google’s online game platform, with services and user experiences designed to bring players together and take Android and mobile games to the next level.

Google Play Games has grown at tremendous speed, activating 100 million users in the past 6 months. It’s the fastest growing mobile game network, and with such an incredible response, we announced more awesome enhancements to Google Play Games today.

Game Profile

The Play Games app now gives players a Game Profile, where they earn points and vanity titles from unlocking achievements. Players can also compare their profile with friends. Developers can benefit from this meta-game by continuing to design great achievements that reward players for exploring all the content and depth of their game.

Quests and Saved Games

Two new game services will launch with the next update for Google Play Services on Android, and through the Play Games iOS SDK:

  • Quests is a service that enables developers to create online, time-based goals in their games without having to launch an update each time. Now developers can easily run weekend or daily challenges for their player community, and reward them in unique ways.
  • Saved Games is a service that stores a player’s game progress across many screens, along with a cover image, description and total time played. Players never have to play level 1 again by having their progress stored with Google, and cover images and descriptions are used in Play Games experiences to indicate where they left off and attract them to launch their favorite game again.

We have many great partners who have started integrating Quests and Saved Games, here are just a few current or upcoming games.

More tools for game developers

Other developer tools are now available for Play Games, including:

  • Play Games Statistics — Play Games adopters get easy effort game analytics through the Google Play Developer console today, including visualization of Player & Engagement statistics. What’s new is aggregated player demographic information for signed-in users, so you can understand the distribution of your player’s ages, genders and countries.
  • Play Games C++ SDK is updated with more cross-platform support for the new services and experiences we announced. Cocos2D-x, a popular game engine, is an early adopter of the Play Games C++ SDK bringing the power of Play Games to their developers.

Game enhancements for the Android Platform

With the announcement of the developer preview of the Android L-release, there are some new platform capabilities that will make Android an even more compelling platform for game development.

  • Support for OpenGL ES 3.1 in the L Developer Preview — Introducing powerful features like compute shaders, stencil textures, and texture gather, enables more interesting physics or pixel effects on mobile devices. Additional API and shading language improvements improve usability and reduce overhead.
  • Android Extension Pack (AEP) in the L Developer Preview — a new set of extensions to OpenGL ES that bring desktop class graphics to Android. Games will be able to take advantage of tessellation and geometry shaders, and use ASTC texture compression.

    We're pleased to be working with different GPU vendors to adopt AEP including Nvidia, ARM, Qualcomm, and Imagination Technologies.

  • Google Gamepad standards — We recently published a standard for gamepad input for OEMs and partners who create and enable these awesome input devices on Android. The standard makes this input mechanism compatible across Google platforms on Android, Chrome and Chromebooks. You can learn more here: Supporting Game Controllers.

Play Games on Android TV

And Google's game network is a part of the Android TV announcement — so think of Android on a TV, with a rich interface on a large screen, and fun games in your living room! Players will be able to earn achievements, climb leaderboards and play online with friends from an Android TV. This is only available through the developer preview, so game developers seeking a hardware development kit (the ADT-1) can make a request at http://developer.android.com/tv.

Updates rolling out soon

That’s a lot of games announcements! Our Play Games changes will roll out over the next few weeks with the update of Google Play Services and the Play Games App, and Android L-release changes are part of the announced developer preview. This gets us a big step closer to a world where Android and our cloud services enable games to reach all the screens in your life and connect you with others.

New Demographic Stats in Google Play Games Services

By Ben Frenkel, Google Play Games team

Hey game developers, back in March you may remember we added new game statistics in the Google Play Developer Console for those of you who had implemented Google Play Games: our cross-platform game services for Android, iOS and the web.

Starting today, we're providing more insights into how your games are being used by adding country, age, and gender dimensions to the existing set of reports available in the Developer console. You’ll see demographics integrated into Overview stats as well as the Players reports for New and Active users.

In the Overview stats you can now see highlights of activity by age group, most active countries, and gender.

With a better understanding of your users’ demographic composition, you'll be able to make more effective decisions to improve retention and monetization. Here a few ways you could imagine using these new stats:

  • You just launched your new game globally, and expected it do particularly well in Germany. Using country demographic data, you see that Germany is much less active than expected. After some digging, you realize that your tutorial was not properly translated to German. Based on this insight, you immediately roll out a fix to see if you can improve active users in Germany.

In the Players stats section the new metrics reveal trends in how your app is doing across age groups, countries, and gender.

  • After Looking at your new demographics report you realize that your game is really popular with women in their mid-20s. Your in-app purchase data corroborates this, showing that the one female hero character is the most popular purchase. Empowered by this data, you race to add female hero characters to your game.

Additionally, if you're already using Google Play game services, there's no extra integration needed! By logging in to the Google Play Developer Console you can start using demographics to better inform your decisions today.

Unlocking the Power of Google for Your Games, at GDC

By Greg Hartrell, Google Play Games team

Today, everyone is a gamer. In fact, 3 in every 4 Android users are playing games, allowing developers to reach an unprecedented audience of players in an Android ecosystem that’s activated over one billion devices. This has helped Google Play Games — Google’s cross-platform game service and SDK for Android, iOS and the web (which lets you easily integrate features like achievements, leaderboards, multiplayer and cloud save into your games) — grow at tremendous speed. The momentum continues on Google Play, where four times more money was paid out to developers in 2013 than in 2012.

With the Game Developers Conference (GDC) this week, we'll be launching a number of new features for Google Play Games and other Google products. As they launch over the coming weeks, these new services and tools will help you unlock the power of Google to take your games to the next level.

Power your game and get discovered

With game gifts, players in your games can send virtual in-game objects to anyone in their circles or through multiplayer search.

To help players get the most out of your games, Play Games will be expanding engagement and discovery options.

We'll be introducing game gifts, a new service that lets players send virtual in-game objects to anyone in their circles or through player search. The Play Games app now supports multiplayer invites directly, further helping players discover your game and keep them playing. And the Google Play Store will also feature 18 new game categories, making it easier for players to find games they'll love.

Tools to take your game to the next level

Further enhancing Google Play Game services, we're expanding multiplayer to support iOS, bringing turn-based and real-time multiplayer capabilities to both Android and iOS.

To further help with cross platform game development, we're updating our Play Games Unity Plug-in to support cross-platform multiplayer services, and introducing an early Play Games C++ SDK to support achievements and leaderboards.

In addition, we're launching enhanced Play Games statistics on the Google Play Developer Console, providing easy game analytics for Play Games adopters. Developers will gain a daily dashboard that visualizes player and engagement statistics for signed in users, including daily active users, retention analysis and achievement, and leaderboard performance.

Ad features to better optimize your business

Of course, once you build a great gaming experience, it's important to get rewarded for your work, which is why we'll also be introducing new features to the AdMob platform. We're making Google Analytics available directly in the AdMob interface, so you can gain deeper insights into how users are interacting with your app. Turning those insights into effective action is vital, so we're excited by the opportunities that in-app purchase ads will offer — enabling you to target users with specific promotions to buy items in your game. Advertising continues to be a core vehicle driving many game developers' success, so we're also bringing you new ways to optimize your ads to earn the most revenue.

Where to find us at GDC

That's just a taste of some of the things we'll be talking about this week at GDC. On Tuesday, March 18, when most of these features will become available, we'll be hosting a Developer Day to dive into these topics in more detail. We'll be talking with you about how to reach and engage with hundreds of millions of users on Google Play, build Games that scale in the cloud, grow in-game advertising businesses with AdMob, track revenue with Google Analytics, as well as explore new gaming frontiers, like Glass.

If you can't make any of the Google Developer Day sessions, don't worry; all the talks will be livestreamed on YouTube, starting at 10:00AM PDT (5:00PM UTC). You can also meet the Play, AdMob, Analytics, and Cloud teams at the Google Education Center in the Moscone Center's South Hall (booth 218) from March 19-21.
