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.
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.
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.
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.
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.
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.
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.
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.
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.
Check out developer.android.com/distribute over the coming weeks and months as we add I/O videos and more details about these and other new features.

The Google Play Developer Console makes a wealth of data available to you so you have the insight needed to successfully publish, grow, and monetize your apps and games. We appreciate that some developers want to access and analyze their data beyond the visualization offered today in the Developer Console, which is why we’ve made financial information, crash data, and user reviews available for export. We're now also making all the statistics on your apps and games (installs, ratings, GCM usage, etc.) accessible via Google Cloud Storage.
We’ve added a Reports tab to the Developer Console so that you can view and access all available data exports in one place.
This is the easiest and most reliable way to download your Google Play Developer Console statistics. You can access all of your reports, including install statistics, reviews, crashes, and revenue.
This new Google Cloud Storage access will open up a wealth of possibilities. For instance, you can now programmatically:
Your data is available in a Google Cloud Storage bucket, which is most easily accessed using gsutil. To get started, follow these three simple steps to access your reports:
gsutil ls
gsutil cp
Read more about exporting report data in the Google Play Developer Help Center.
Note about data ownership on Google Play and Cloud Platform: Your Google Play developer account is gaining access to a dedicated, read-only Google Cloud Storage bucket owned by Google Play. If you’re a Google Cloud Storage customer, the rest of your data is unaffected and not connected to your Google Play developer account. Google Cloud Storage customers can find out more about their data storage on the terms of service page.

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:
“With player engagement and revenue data living under one roof, developers get a level of data quality that is simply not available to smaller teams without dedicated staff. As the tools evolve, I think Google Play Games Player Analytics will finally allow indie devs to confidently make data-driven changes that actually improve revenue.”
Kevin Pazirandeh Developer of Zombie Highway 2
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.
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.
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).

Starting today, anyone can take their apps for a drive with Android Auto using Android 5.0+ devices, connected to compatible cars and aftermarket head units. Android Auto lets you easily extend your apps to the car in an efficient way for drivers, allowing them to stay connected while still keeping their hands on the wheel and their eyes on the road. When users connect their phone to a compatible vehicle, they will see an Android experience optimized for the head unit display that seamlessly integrates voice input, touch screen controls, and steering wheel buttons. Moreover, Android Auto provides consistent UX guidelines to ensure that developers are able to create great experiences across many diverse manufacturers and vehicle models, with a single application available on Google Play.
With the availability of the Pioneer AVIC-8100NEX, AVIC-7100NEX, and AVH-4100NEX aftermarket systems in the US, the AVIC-F77DAB, AVIC-F70DAB, AVH-X8700BT in the UK, and in Australia the AVIC-F70DAB, AVH-X8750BT, it is now possible to add Android Auto to many cars already on the road. As a developer, you now have a way to test your apps in a realistic environment. These are just the first Android Auto devices to launch, and vehicles from major auto manufacturers with integrated Android Auto support are coming soon.
With the increasing adoption of Android Auto by manufacturers, your users are going to be expecting more support of their apps in the car, so now is a good time to get started with development. If you are new to Android Auto, check out our DevByte video, which explains more about how this works, along with some live demos.
The SDK for Android Auto was made available to developers a few months ago, and now Google Play is ready to accept your application updates. Your existing apps can take advantage of all these cool new Android Auto features with just a few small changes. You’ll need to add Android Auto support to your application, and then agree to the Android Auto terms in the Pricing & Distribution category in the Google Play Developer Console. Once the application is approved, it will be made available as an update to your users, and shown in the cars’ display.
Adding support for Android Auto is easy. We have created an extensive set of documentation to help you add support for messaging (sample), and audio playback (sample). There are also short introduction DevByte videos for messaging and audio as well. Stay tuned for a series of posts coming up soon discussing more details of these APIs and how to work with them. We also have simulators to help you test your applications right at your desk during development.
With the launch of Android Auto, a new set of possibilities are available for you to make even more amazing experiences for your users, providing them the right information for the road ahead. Come join the discussion about Android Auto on Google+ at http://g.co/androidautodev where you can share ideas and ask questions with other developers.

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.
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.
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.

Knowing how your customers use your app is the foundation to keeping them happy and engaged. It’s important to track downloads and user ratings, but the key to building a successful business is using data to dive deeper into understanding the full acquisition funnel and what makes users stick around.
Google Analytics is the easiest way to understand more about what your users are doing inside your app on Google Play, while also simultaneously tracking your users across the web and other mobile platforms. To show how Google Analytics can help, we've created a new "Analyze" section on the Android Developers website for you to check out. We provide guidance on how to design a measurement plan and implement effective in-app analytics – and take advantage of features only available between Google Play and Google Analytics.
Google Analytics for mobile apps provides a comprehensive view into your app’s full user lifecycle, including user acquisition, composition, in app behavior, and key conversions. Our Analytics Academy course on mobile app analytics is also a great resource to learn the fundamentals.
Eltsoft LLC, a foreign language learning and education app developer for Android, recognized early on how impactful Google Analytics would have on the company's ability to quickly improve on its apps and meet user needs.
Analytics has really helped us to track the effectiveness of the changes to our app. I would say six months ago, that our success was a mystery. The data said we were doing well, but the whys were not clear. Therefore, we couldn’t replicate or push forward. But today, we understand what’s happening and can project our future success. We have not only the data, but can control certain variables allowing us to understand that data. - Jason Byrne, Eltsoft LLC
Here are some powerful tips to make the most of Google Analytics:
By measuring your app performance on a granular level, you will be able to make better decisions for your business. Successful developers build their measurement plan at the same time as building their app in order to set goals and track progress against key success metrics, but it’s never too late to start.
Choose the implementation that works best for your app to get started with Google Analytics today and find out more about what you can do in the new “Analyze” section of developers.android.com.

If you're growing your business on Google Play, the Google Play Developer Console is one of the most important tools at your disposal. At Google I/O, we introduced a number of new changes that give you valuable insight into how your app is performing. Here's an overview of some of the improvements you can now take advantage of.
Today we're happy to announce that the Google Play Developer Publishing API is now available to all developers. The API will let you upload APKs to Beta testing, Staged rollout and Production, and integrate publishing operations with your release processes and toolchain. The Publishing API also makes it easier for you to manage your in-app products catalog, provide tablet-specific screenshots, and localize your store listing text and graphics. The Publishing API will help you focus on your core business, with less time managing your releases, even as your business grows to more apps and markets.
Recently, we added Alerts in the Developer Console to let you know when there are sudden changes in important stats like app installs, ratings, and crashes. You can now turn on email notifications for Alerts so that, even while you’re not in the Developer Console, you’ll be informed of relevant events before they can have a broader effect on your app. You can turn on email notifications for one or more of your apps under Email Preferences in the Developer Console settings.
You’ll now see new Optimization Tips with instructions when we detect opportunities to improve your app. For example, we’ll let you know when updated versions of APIs you use are available — such as new Google Play in-app billing or Google Maps APIs. For games developers, we’ll also surface opportunities to use Google Play game services that can help improve users’ gaming experience and drive engagement. To see what tips we suggest for you, go to your app in the Developer Console and click on Optimization Tips.
To help you better understand your commercial success, we’ve enhanced revenue statistics in the Finance section of the Developer Console. We now let you see the average revenue per paying user (ARPPU) and give you more ways to analyse buyer data, such as comparing returning buyers (i.e., those who also made purchases in the past) to new buyers.
You can already engage with your users by reading and replying to reviews in the Developer Console and we’ve now added bulk export of reviews so you can download and analyze your app’s reviews en masse. This is particularly useful if you receive a large volume of reviews and want to perform your own sentiment analysis.
Since last year’s launch, you’ve used beta testing to release alpha and beta versions of your app, and staged rollout to gradually launch your app to production. To help you make the most of this feature, we’re now improving the way alpha, beta and staged rollout specific stats are displayed. When viewing your app and crash statistics you can now filter the app version by alpha, beta, or staged rollout to better understand the impact of your testing.
If you develop in native code, we’ve improved the reporting and presentation specifically for native crashes, with better grouping of similar crashes and summarizing of relevant information.
Finally, we’ve also added website verification in the Developer Console, to enable deep-linking to your app from search results. Deep-linking helps remind users about the apps they already have. It is available through search for all apps that implement app indexing. For example, if a user with the Walmart Android app searches for “Chromecast where to buy”, they’ll go directly to the Chromecast page in the Walmart app. The new App Indexing API is now open to all Android developers, globally. Get started now.
We hope you find these features useful and take advantage of them so that you can continue to grow your user base and improve your users’ experience. If you're interested in some other great tools for distributing your apps, check out this blog post, or any of the sessions which have now been posted to the Google Developers Channel.

Today we are happy to announce that the App Translation Service, previewed in May at Google I/O, is now available to all developers. Every day, more than 1.5 million new Android phones and tablets around the world are turned on for the first time. Each newly activated Android device is an opportunity for you as a developer to gain a new user, but frequently, that user speaks a different language from you.
To help developers reach users in other languages, we launched the App Translation Service, which allows developers to purchase professional app translations through the Google Play Developer Console. This is part of a toolbox of localization features you can (and should!) take advantage of as you distribute your app around the world through Google Play.
We were happy to see that many developers expressed interest in the App Translation Service pilot program, and it has been well received by those who have participated so far, with many repeat customers.
Here are several examples from developers who participated in the App Translation Service pilot program: the developers of Zombie Ragdoll used this tool to launch their new game simultaneously in 20 languages in August 2013. When they combined app translation with local marketing campaigns, they found that 80% of their installs came from non-English-language users. Dating app SayHi Chat expanded into 13 additional languages using the App Translation Service. They saw 120% install growth in localized markets and improved user reviews of the professionally translated UI. The developer of card game G4A Indian Rummy found that the App Translation Service was easier to use than their previous translation methods, and saw a 300% increase with user engagement in localized apps. You can read more about these developers’ experiences with the App Translation Service in Developer Stories: Localization in Google Play.
To use the App Translation Service, you’ll want to first read the localization checklist. You’ll need to get your APK ready for translation, and select the languages to target for translation. If you’re unsure about which languages to select, Google Play can help you identify opportunities. First, review the Statistics section in the Developer Console to see where your app has users already. Does your app have a lot of installs in a certain country where you haven’t localized to their language? Are apps like yours popular in a country where your app isn’t available yet? Next, go to the Optimization Tips section in the Developer Console to make sure your APK, store listing, and graphics are consistently translated.
You’ll find the App Translation Service in the Developer Console at the bottom of the APK section — you can start a new translation or manage an existing translation here. You’ll be able to upload your app’s file of string resources, select the languages you want to translate into, select a professional translation vendor, and place your order. Pro tip: you can put your store listing text into the file you upload to the App Translation Service. You’ll be able to communicate with your translator to be sure you get a great result, and download your translated string files. After you do some localization testing, you’ll be ready to publish your newly translated app update on Google Play — with localized store listing text and graphics. Be sure to check back to see the results on your user base, and track the results of marketing campaigns in your new languages using Google Analytics integration.
Good luck! Bonne chance ! ご幸運を祈ります! 행운을 빌어요 ¡Buena suerte! Удачи! Boa Sorte!
