Google Play games services includes Player Analytics, a free reporting tool available in the Google Play Developer Console, to help you understand how players are progressing, spending, and churning. Now, you can see what Player Analytics looks like with an exemplary implementation of Play games services: try out the new sample game in the Google Play Developer Console, which we produced with help from Auxbrain, developer of Zombie Highway 2. The sample game uses randomized and anonymized data from a real game and will also let you try the new features we’re announcing today. Note: You need a Google Play Developer account in order to access the sample game.

To help you better understand your players’ behavior, we’ve extended the Player Stats API in Player Analytics with predictive functionality. The churn prediction method will return data on the probability that the player will churn, i.e., stop playing the game, so you can create content in response to this to entice them to stay in your game. Additionally, the spend prediction method will return the probability that the player will spend, and you could, for example, provide discounted in-app purchases or show ads based on these insights.

The funnels report enables you to create a funnel chart from any sequence events, such as achievements, spend, and custom events. For example, you could log custom events for each step in a tutorial flow (e.g., tutorial step 1, step 2, step 3), and then use the funnel report to visualize the exit points in your tutorial.

The cohorts report allows you to take any event such as sessions, cumulative spend, and custom events, and compare the cumulative event values by new user cohorts - providing valuable insight into the impact of your decisions on your gaming model. For example, you can view users that started the day before you made a change and the day after. This allows you to measure and compare the effect of changes made, so if you doubled the price of all your items in your in-game store, you can see if the cumulative sessions started after the change was lower or higher than the users that started before the change.

We have updated the C++ and iOS SDKs, and the Unity plug-in, all of which now support the Player Stats API, which includes the basic player stats as well as spend and churn predictions.

Be sure to check out the sample game and learn more about Play Games Services. You can also get top tips from game developer Auxbrain to help you find success with Google Play game services.

Over the past six months, a number of new tools in the Google Play Developer Console have been added to help you grow your app or game business on Google Play. Our improved beta testing features help you gather more feedback and fix issues. Store Listing Experiments let you run A/B tests on your app’s Play Store listing. Universal App Campaigns and the User Acquisition performance report help you grow your audience and better understand your marketing.

Starting today, you can now generate and distribute promo codes to current and new users on Google Play to drive engagement. Under the Promotions tab in the Developer Console, you can set up promo codes for your apps, games, and in-app products to distribute in your own marketing campaigns (up to 500 codes per app, per quarter). Consider using promo codes to reward loyal users and attract new customers.

How to use promo codes

1. Choose your app in the Developer Console.
   
2. Under the Promotions tab choose Add new promotion.
   
   
   
   
3. Review and accept the additional terms of service if you haven’t run a promotion before.
   
4. Choose from the options available, then generate and download your promo codes.
   
5. Distribute your promo codes via your marketing channels such as social networks, in email, on the web, to your app’s beta testers, or in your app or game itself.
   
6. Users can redeem your promo codes in a number of ways, including:
   

1. From Google Play, using the Redeem menu option.
   
2. From your app. They’ll be directed to the Play checkout flow before being redirected back to your app.
   
3. By following a link that embeds the promo code (see tips below).
   

For more details about running a promotion for your app or game, read this article on the Google Play Developer Help Center.

Tips for making the most of promo codes

Some things to keep in mind when running a successful promotion:

• There’s a limit of 500 promo codes per app every quarter.


• You can embed your code in a URL so that users don’t have to enter it themselves (for example, if you’re sending your codes in an email). You can use the URL: https://play.google.com/redeem?code={CODE} (where {CODE} is a generated promo code).


• To use promo codes for in-app products, you should implement In-app Promotions in your app. Note that promo codes can’t be used for subscriptions.


• Review and adhere to the Promotional Code Terms Of Service.

We hope you find interesting ways to use promo codes to find new users and engage existing fans. To learn more about the many tools and best practices you can use to grow your business on Google Play, download our new developer playbook, “The Secrets to App Success on Google Play”.

Available in more than 190 countries, Google Play is a global platform for developers to build high quality apps and successful businesses. But every market has its own unique challenges and opportunities. Purchasing behavior, in particular, varies significantly between markets. So to provide developers with more flexibility, we've worked to adapt Google Play pricing options to better suit local consumers and make content more accessible.

Following a successful pilot in India earlier this year, today, developers have the option to reduce the price of their premium titles and in-app products in 17 more countries to these new minimum thresholds:

Countries affected:

• Brazil: R$ 0.99 (was R$2.00)


• Chile: CLP $200.00 (was CLP $500.00)


• Colombia: COP$ 800.00 (was COP$ 2000.00)


• Egypt: E£2 Previous (was E£7)


• Hungary: Ft 125.00 (was Ft 225.00)


• Indonesia: Rp 3,000.00 (was Rp 12,000.00)


• Malaysia: RM 1.00 (was RM 3.50)


• Mexico: MXN$ 5.00 (was MXN$ 9.90)


• Nigeria: ₦40 (was ₦195)


• Peru: S/. 0.99 (was S/. 3.00)


• Philippines: ₱15.00 (was ₱43.00)


• Poland: zł1.79 (was zł2.99)


• Russia: руб 15.00 (was руб 30.00)


• Saudi Arabia:﷼ 0.99 (was 4.00﷼)


• South Africa: R3.99 (was R10.00)


• Thailand: ฿10.00 (was ฿32.00)


• Turkey: ₺0.59 (was ₺2.00)


• Ukraine: ₴5.00 (was ₴8.00)


• Vietnam: ₫6,000 (was ₫21,000.00)

You can lower the price of your apps and games right away by visiting the Google Play Developer Console and clicking on “Pricing & Distribution” or “In-app Products” for your apps.

We hope this change allows you to reach more people around the world so that you can continue to grow your business on Google Play.

Smartphones are powerful devices that can support diverse tasks from graphically intensive games to helping people get work done from anywhere. We understand that developers are challenged with delivering a delightful user experience that maximizes the hardware of the device, while also ensuring that their users can download, install, and open the app as quickly as possible. It’s a tough balance to strike, especially when you’re targeting diverse global audiences.

To support the growing number of developers who are building richer apps and games on Google Play, we are increasing the APK file size limit to 100MB from 50MB. This means developers can publish APKs up to 100MB in size, and users will see a warning only when the app exceeds the 100MB quota and makes use of Expansion Files. The default update setting for users will continue to be to auto-updating apps over Wi-Fi only, enabling users to access higher quality apps and games while conserving their data usage.

Even though you can make your app bigger, it doesn’t always mean you should. Remember to keep in mind the following factors:

• Mobile data connectivity: Users around the world have varying mobile data connectivity speeds. Particularly in developing countries, many people are coming online with connections slower than those of users in countries like the U.S. and Japan. Users on a slow connection are less likely to install an app or game that is going to take a long time to download.


• Mobile data caps: Many mobile networks around the world give users a limited number of MB that they can download each month without incurring additional charges. Users are often wary of downloading large files for fear of exceeding their limits.


• App performance: Mobile devices have limited RAM and storage space. The larger your app or game, the slower it may run, particularly on older devices.


• Install time: People want to start using your app or game as quickly as possible after tapping the install button. Longer wait times increase the risk they’ll give up.

We hope that, in certain circumstances, this file size increase is useful and enables you to build higher quality apps and games that users love.

We know how important it is for you to efficiently develop the skills to build better Android apps and be successful in your jobs. To meet your training needs, we’ve partnered with Udacity to create Android training courses, ranging from beginner to more advanced content.

Last week at Google I/O we announced the Android Nanodegree, an education credential that is designed for busy people to learn new skills and advance their careers in a short amount of time from anywhere at any time. The nanodegree ties together our Android courses, and provides you with a certificate that may help you be a more marketable Android developer.

Training courses

All training courses are developed and taught by expert Google instructors from the Developer Platform team. In addition to updating our popular Developing Android Apps course and releasing Advanced Android App Development, we now have courses for everyone from beginning programmers to advanced developers who want to configure their Gradle build settings. And then there's all the fun stuff in between—designing great-looking, high performance apps, making your apps run on watches, TVs, and in cars, and using Google services like Maps, Ads, Analytics, and Fit.

Each course is available individually, without charge, at udacity.com/google. Our instructors are waiting for you:

Android Nanodegree

You can also enroll in the new Android Nanodegree for a monthly subscription fee, which gives you access to coaches who will review your code, provide guidance on your project, answer questions about the class, and help keep you on track when you need it.

More importantly, you will learn by doing, focusing only on where you need to grow. Since the Nanodegree is based on your skills and the projects in your portfolio, you do not need to complete the courses that address the skills you already have. You can focus on writing the code and building the projects that meet the requirements for the Nanodegree credential.
We’ll also be inviting 50 Android Nanodegree graduates to Google's headquarters in Mountain View, California, for a three day intensive Android Career Summit in November. Participants will have the opportunity to experience Google’s company culture and attend workshops focused on developing their personal career paths. Participants will then leverage the skills learned from Udacity’s Android Nanodegree during a two-day hackathon.

To help you learn more about this program and and courses within it, Google and Udacity are partnering up for an "Ask the Experts" live streamed series. In the first episode on Wednesday, June 3rd at 2pm PDT, Join Sebastian Thrun, Peter Lubbers and Jocelyn Becker who will be answering your questions on the Nanodegree. RSVP here and ask and vote for questions here.

Android training in Arabic

We also believe that everyone has the right to learn how to develop Android apps. Today, there is a great need for developers in countries outside of the United States as software powers every industry from food and transportation to healthcare and retail. As a first step in getting the Android Nanodegree localized and targeted for individual countries, we have worked with the Government of Egypt and Udacity to create end-to-end translations of our top Android courses into Arabic (including fully dubbed video). Google will offer 2,000 scholarships to students to get a certificate for completing the Arabic version of the Android Fundamentals course. Google will also host job fairs and sessions for students with local employers and the Egyptian Government. For more information, see www.udacity.com/egypt.

With more than 50 billion app installs over the past year from users across 190 countries, Google Play continues to see incredible growth thanks to developers like you creating amazing experiences. Play is now reaching more than one billion users every month.

In February, we announced that we had paid out more than $7 billion to developers in the prior year alone. This week at Google I/O, we’re introducing new and powerful tools to help you further grow your business, improve decision making based on smarter insights, and better engage your user base with more relevant content.

Acquire users from the Developer Console

Once you’ve built a great app, the next important step is to proactively find ways to promote it and grow a loyal user base. App install ads are one powerful way to do that. In the coming months, you’ll be able to quickly and easily set up ad campaigns right from within the Google Play Developer Console for the first time.

All you need to do is set a total budget and the cost you're willing to pay per user and we’ll scale your app promotion across our networks, including Google Search, AdMob, YouTube and the search ads we’re piloting on Google Play. With this new feature, you will will be able to better find the customers that are most likely to install your app.

Actionable insights with the Acquisition and Conversion Funnel

Whether you pay to acquire users or not, you want to know where they’re coming from. Through the Developer Console, you will soon be able to get a snapshot of how many users visit your Store listing, install your app, and make purchases. You’ll see where your most valuable users come from — across organic and paid traffic — and better understand where to focus your efforts.

Optimize your Play store listing with experiments

Your Play Store listing is extremely important, as it’s often the first touch point users have with your app. Starting today, we’re making it easier to optimize this page with support for A/B tests. You can run experiments with different versions of text and graphics to see which are most effective in converting visits into installs on Google Play. In our pilot program, we were thrilled to see that some developers like Kongregate achieved double-digit improvements in their install rates so far.

Test your app automatically on real devices with Cloud Test Lab

With the large variety of Android form factors in the market, testing your app on real devices is a critical step to ensuring a positive user experience on any device. However, you may not have access to every device that your users do. So we’re integrating the newly announced Cloud Test Lab into the Developer Console, which will allow you to automatically test your apps on hundreds of popular physical Android devices for free. We’re going to be rolling out this pilot program gradually, so we’ll welcome your feedback on it.

For each APK you upload to an alpha or beta channel, Google Play will execute fully automated testing of your app against physical devices matching your app targeting criteria and output a report with a detailed analysis of issues, including screenshots and logs. Google Cloud Test Lab will roll out to all developers later this year; you can sign-up to become a tester in the Developer Console now.

Build a data-driven games business with Player Analytics

Google Play Games has activated more than 180M new users in the past six months and continues to be the fastest growing mobile gaming platform in history.

Over the coming months, we're adding new reports, player segments, game metrics, and event types to Player Analytics to help you manage your games business. We're also bringing enhancements to our live operations tools that will enable dynamic content updates that make games feel more alive and engaging, gameplay to respond to changing player needs, and more fun, personalized user experiences. As the bar for success in mobile gaming continues to rise, we’re continuing to evolve our tools to help you meet the soaring expectations of players.

Find great apps – developer pages and search results

There are several ways in which we are improving the discoverability of great apps and games on Google Play to help drive more engagement. Starting today, you can create a unique homepage on Google Play to promote your entire app catalog. With your own developer page, you are able to upload graphics, explain what your company is all about and pick a special app to feature. This gives you a single destination to promote all of your apps on Google Play.

We are also helping guide users with broad interests (e.g. “shopping”) in a new search results experience.

The focus is on organizing results in an intuitive way that allows users to narrow their intent -- such as grouping shopping apps into coupons apps and fashion apps. By doing so, users will be able to better see the range of apps that satisfy their needs, while also increasing the chances of discovering new and innovative apps that you’re building.

Family-friendly content in Google Play

Starting today, we’re making it easier to find family-friendly content on Google Play through new discovery features. On the Apps & Games and Movies & TV homepages, users can now hit the “Family” star to see a curated set of options for specific age groups. In Play Books, tap the “Children’s Books” star. These pages let you browse by age ranges to find content that’s the best fit for the family. If you’ve already opted-in your apps to the Designed for Families program and they’ve met the requirements, they’ll be included in the new family section so that parents can find suitable, trusted, high-quality apps and games more easily. Find out more about opting-in to the Designed for Families program.

Join us at Google I/O 2015

To learn more, tune-in live to “Developers connecting the world through Google Play” at 1pm PT / 4pm ET / 9pm GMT on May 29 on google.com/io.

If you’re at I/O 2015, come along to our breakout sessions where we’ll be talking about and demo’ing these new features. Find our sessions in the I/O 2015 schedule.

You’ve invested time and effort into making your app an awesome experience, and we want to help people find the great content you’ve created. App Indexing has already been helping people engage with your Android app after they’ve installed it — we now have 30 billion links within apps indexed. Starting this week, people searching on Google can also discover your app if they haven’t installed it yet. If you’ve implemented App Indexing, when indexed content from your app is relevant to a search done on Google on Android devices, people may start to see app install buttons for your app in search results. Tapping these buttons will take them to the Google Play store where they can install your app, then continue straight on to the right content within it.

With the addition of these install links, we are starting to use App Indexing as a ranking signal for all users on Android, regardless of whether they have your app installed or not. We hope that Search will now help you acquire new users, as well as re-engage your existing ones. To get started, visit g.co/AppIndexing and to learn more about the other ways you can integrate with Google Search, visit g.co/DeveloperSearch.

There are thousands of Android developers creating experiences for families and children — apps and games that broaden the mind and inspire creativity. These developers, like PBS Kids, Tynker and Crayola, carefully tailor their apps to provide high quality, age appropriate content; from optimizing user interface design for children to building interactive features that both educate and entertain.

Google Play is committed to the success of this emerging developer community, so today we’re introducing a new program called Designed for Families, which allows developers to designate their apps and games as family-friendly. Participating apps will be eligible for upcoming family-focused experiences on Google Play that will help parents discover great, age-appropriate content and make more informed choices.

Starting now, developers can opt in their app or game through the Google Play Developer Console. From there, our team will review the submission to verify that it meets the Designed for Families program requirements. In the coming weeks, we’ll be adding new ways to promote family content to users on Google Play — we’ll have more to share on this soon.

A few weeks ago at the Game Developers Conference (GDC), we announced Play Games Player Analytics, a new set of free reports to help you manage your games business and understand in-game player behavior. Today, we’re excited to make these new tools available to you in the Google Play Developer Console.

Analytics is a key component of running a game as a service, which is increasingly becoming a necessity for running a successful mobile gaming business. When you take a closer look at large developers that do this successfully, you find that they do three things really well:

• Manage their business to revenue targets


• Identify hot spots in their business metrics so they can continuously focus on the game updates that will drive the most impact


• Use analytics to understand how players are progressing, spending, and churning

With Player Analytics, we wanted to make these capabilities available to the entire developer ecosystem on Google Play in a frictionless, easy-to-use way, freeing up your precious time to create great gaming experiences. Small studios, including the makers of Zombie Highway 2 and Bombsquad, have already started to see the benefits and impact of Player Analytics on their business.

Further, if you integrate with Google Play game services, you get this set of analytics with no incremental effort. But, for a little extra work, you can also unlock another set of high impact reports by integrating Google Play game services Events, starting with the Sources and Sinks report, a report to help you balance your in-game economy.

If you already have a game integrated with Google Play game services, go check out the new reports in the Google Play Developer Console today. For everyone else, enabling Player Analytics is as simple as adding a handful of lines of code to your game to integrate Google Play game services.

Manage your business to revenue targets

Set your spend target in Player Analytics by choosing a daily goal

To help assess the health of your games business, Player Analytics enables you to select a daily in-app purchase revenue target and then assess how you're doing against that goal through the Target vs Actual report depicted below. Learn more.

Identify hot spots using benchmarks with the Business Drivers report

Ever wonder how your game’s performance stacks up against other games? Player Analytics tells you exactly how well you are doing compared to similar games in your category.

Metrics highlighted in red are below the benchmark. Arrows indicate whether a metric is trending up or down, and any cell with the icon can be clicked to see more details about the underlying drivers of the change. Learn more.

Track player retention by new user cohort

In the Retention report, you can see the percentage of players that continued to play your game on the following seven days after installing your game.

Learn more.

See where players are spending their time, struggling, and churning with the Player Progression report

Measured by the number of achievements players have earned, the Player Progression funnel helps you identify where your players are struggling and churning to help you refine your game and, ultimately, improve retention. Add more achievements to make progression tracking more precise.

Learn more.

Manage your in-game economy with the Sources and Sinks report

The Sources and Sinks report helps you balance your in-game economy by showing the relationship between how quickly players are earning or buying and using resources.

For example, Eric Froemling, one man developer of BombSquad, used the Sources & Sinks report to help balance the rate at which players earned and spent tickets.

Read more about Eric’s experience with Player Analytics in his recent blog post.

To enable the Sources and Sinks report you will need to create and integrate Play game services Events that track sources of premium currency (e.g., gold coins earned), and sinks of premium currency (e.g., gold coins spent to buy in-app items).

Whether it's a way to track workouts, chart the nighttime stars, or build a new reality and battle for world domination, Google Play gives developers a platform to create engaging apps and games and build successful businesses. Key to that mission is offering users a positive experience while searching for apps and games on Google Play. Today we have two updates to improve the experience for both developers and users.

A global content rating system based on industry standards

Today we’re introducing a new age-based rating system for apps and games on Google Play. We know that people in different countries have different ideas about what content is appropriate for kids, teens and adults, so today’s announcement will help developers better label their apps for the right audience. Consistent with industry best practices, this change will give developers an easy way to communicate familiar and locally relevant content ratings to their users and help improve app discovery and engagement by letting people choose content that is right for them.

Starting now, developers can complete a content rating questionnaire for each of their apps and games to receive objective content ratings. Google Play’s new rating system includes official ratings from the International Age Rating Coalition (IARC) and its participating bodies, including the Entertainment Software Rating Board (ESRB), Pan-European Game Information (PEGI), Australian Classification Board, Unterhaltungssoftware Selbstkontrolle (USK) and Classificação Indicativa (ClassInd). Territories not covered by a specific ratings authority will display an age-based, generic rating. The process is quick, automated and free to developers. In the coming weeks, consumers worldwide will begin to see these new ratings in their local markets.

To help maintain your apps’ availability on Google Play, sign in to the Developer Console and complete the new rating questionnaire for each of your apps. Apps without a completed rating questionnaire will be marked as “Unrated” and may be blocked in certain territories or for specific users. Starting in May, all new apps and updates to existing apps will require a completed questionnaire before they can be published on Google Play.

An app review process that better protects users

Several months ago, we began reviewing apps before they are published on Google Play to better protect the community and improve the app catalog. This new process involves a team of experts who are responsible for identifying violations of our developer policies earlier in the app lifecycle. We value the rapid innovation and iteration that is unique to Google Play, and will continue to help developers get their products to market within a matter of hours after submission, rather than days or weeks. In fact, there has been no noticeable change for developers during the rollout.

To assist in this effort and provide more transparency to developers, we’ve also rolled out improvements to the way we handle publishing status. Developers now have more insight into why apps are rejected or suspended, and they can easily fix and resubmit their apps for minor policy violations.

Over the past year, we’ve paid more than $7 billion to developers and are excited to see the ecosystem grow and innovate. We’ll continue to build tools and services that foster this growth and help the developer community build successful businesses.

Google Play now reaches more than 1 billion people on Android devices in more than 190 countries, helping a growing number of developers like you build successful global businesses. In fact, in the past year, we paid more than $7 billion to developers distributing apps and games on Google Play. We remain as committed as ever to making Google Play the best place to find great apps, games and other entertainment.

App discovery plays a critical role in driving your continued success, and over the past year Google has provided best practices to enhance app discovery and engagement, as well as app promotion tools to get the most out of search and display advertising for developers. We are always looking for new ways to help you get your apps in front of potential new users. That’s why, in the next few weeks, we will begin piloting sponsored search results on Google Play, bringing our unique expertise in search ads to the store.

With more than 100 billion searches every month on Google.com, we’ve seen how search ads shown next to organic search results on Google.com can significantly improve content discovery for users and advertisers, both large and small. Search ads on Google Play will enable developers to drive more awareness of their apps and provide consumers new ways to discover apps that they otherwise might have missed.

In the coming weeks, a limited set of users will begin to see ads from a pilot group of advertisers who are already running Google search ads for their apps. We’ll have more to share in the coming months about the expansion of this program as we look at the results and feedback. We believe search ads will be a useful addition to Google Play for users and developers alike, and we hope this will bring even more success to our developer community.

Today, more than 50 percent of Trulia’s business comes from mobile and growth shows no sign of slowing, so they know that’s where they need to innovate.

Trulia continues to focus on improving their mobile experience, using Google’s geo-fencing technology to create Nearby Home Alerts, which lets users know when they walk near a new listing. Combined with Android Wear, Trulia now makes it possible for users to see details and photos about a property and call or email the agent, all directly from their watch.
