Many developers are increasingly focused on growing their businesses globally, and there were more than 94 billion apps downloaded from Google Play in the last year, reaching more than 190 countries. The regulatory environment is frequently changing in local markets, and in some countries local governments have implemented withholding tax requirements on transactions with which Google or our payment processor partners must comply. We strive to help both developers and Google meet local tax requirements in markets where we do business, and where Google or our payment processor partners are required to withhold taxes, we may need to deduct those amounts from our payments to developers.
Due to new requirements in some markets, we'll be rolling out withholding taxes soon to all those doing business in those countries. We wanted to bring this to the attention of Google Play developers to allow you time to prepare for these upcoming changes and take any necessary measures to meet these obligations. We strongly recommend developers consult with a professional tax advisor on your individual tax implications in affected markets and for guidance on the potential impact on your business so that you can make any necessary preparations.
The first countries where we will roll out these changes will be Saudi Arabia, Kuwait, and Myanmar. You can refer to the Google Play help center page to stay informed on future updates and changes.

Over the last 10 years, we’ve worked together to build an incredible ecosystem with more than 2.5 billion active users in over 190 countries. This would not be possible without you and all the fantastic apps and games you’ve built that entertain, help, and educate people around the world.
Every month, you upload more than 750,000 APKs and app bundles to the Play Console. We’ve been amazed by your enthusiasm, and it’s been our privilege to help you grow your business. This year, we want to help you go even further. So today at Google I/O, we're announcing new tools and features to help you develop, release, and grow your apps and games — many of them based on your feedback and suggestions.
Last year we introduced Android's new publishing format, the Android App Bundle, and an entirely new dynamic delivery framework on Google Play. There are now over 80,000 apps and games using app bundles in production, with an average size savings of 20%. As a result of those savings, apps have seen up to 11% install uplift. As the future of app delivery, we’re excited to share these latest enhancements to the Android App Bundle.
Dynamic features are out of beta and available to all developers, including these new delivery options:
During our beta program, many developers implemented interesting use cases with dynamic features. Netflix, for example, now delivers their customer support functionality as a dynamic feature to users who visit the support center. By making functionality available only to users who need it, Netflix reported a 33% reduction in app size. You can learn more in the video below.
We heard you loud and clear: testing bundles is hard. But with the new internal app sharing, you can now share test builds in a matter of seconds. Just upload your app bundle to Google Play and get a download URL to share with your testers. You don’t need to worry about version codes, signing keys, or most other validations that your production releases need to conform to.
In addition to efficiency and modularity, the Android App Bundle also now offers increased security with the launch of app signing key upgrade for new installs. With this feature, you can upgrade the cryptographic strength of your signing key for new installs and their updates on Google Play. Many developers sign their apps with keys generated a long time ago, and this new feature is the only backwards-compatible way to increase their strength.
Although auto-updates reach many users, you told us it was still challenging to get some users to update your apps. Now that our new in-app updates API is in general availability, users will be able to update without ever leaving your app. During our early access program, many developers used our API to create a polished upgrade flow, resulting in a median acceptance rate of about 50%.
The API currently supports two flows:
The right data can help you improve your app performance and grow your business. That’s why we’re excited to tell you about new metrics and insights that will help you better measure your app health and analyze your performance.
We’re also making big changes to another key source of performance data: your user reviews. Many of you told us that you want a rating that reflects a more current version of your app, not what it was years ago — and we agree. So instead of a lifetime cumulative value, your Google Play Store rating will be recalculated to give more weight to your most recent ratings. Users won’t see the updated rating in the Google Play Store until August, but you can preview your new rating in the Google Play Console today.
Every day, developers respond to more than 100,000 reviews in the Play Console, and when they do, we’ve seen that users update their rating by +0.7 stars on average. So in addition to the ratings change, we're making it easier to respond to reviews with suggested replies. When you go to respond to a user, you’ll see three suggested replies which have been created automatically based on the content of the review. You can choose to send one as-suggested, customize a suggestion for more personalization, or create your own message from scratch. Suggested replies are available in English now with additional languages coming later.
Your store listing is where users come to learn more about your app or game and decide whether to install. It’s important real estate, so we’re releasing new features that let you optimize your Google Play Store to address different moments in the user lifecycle.
Learn more about these and other Google Play features at Google I/O. Join us live or watch later on the Android Developers YouTube channel.
You can also take your skills and knowledge to the next level with our e-learning courses on Google Play’s Academy for App Success, and sign up for our newsletter to stay up to date with our latest features and updates.

Since launching on Google Play nearly 7 years ago, subscriptions have proven to be an essential element in creating sustainable mobile app businesses; 89 of the top 100 highest grossing apps on Google Play in the US now provide subscription products. As the market matures, it is becoming increasingly important for subscription developers to optimize both subscriber conversion and retention in order to maintain growth. To help you do that, we're rolling out new insights available directly in the Play Console.
Subscription retention report
Example subscription retention report data in the Play Console. Source: Google Internal Data.
The recently updated subscription retention report shows how well you are retaining subscribers, along with how well subscribers convert from free trial, introductory price, and first to second payment.
You can configure two cohorts based on SKU, country, and subscription start date. This is particularly useful for evaluating the success of A/B tests; for example, to determine if changing the duration of a free trial has an impact on free trial conversion.
Example free trial conversion data in the Play Console. Source: Google Internal Data.
Cancellation survey results
Retaining your existing subscribers is just as important as acquiring new subscribers, so we have updated the subscription cancellations report to give more insight into voluntary and involuntary cancellations.
The launch of the subscriptions center last year introduced a cancellation survey allowing users to give developers feedback as to why they were cancelling, with results available through the Google Play Developer API. To make these results easier to access and monitor, we now surface daily aggregates directly within the Play Console, along with the ability to download written responses in a CSV.
Example cancellation survey responses in the Play Console. Source: Google Internal Data.
Recover more users
Involuntary cancellations, which occur when a user's form of payment fails, account for over a third of all cancellations. The new recovery performance cards in the cancellation report helps you understand how effectively you are recovering users with grace period and account hold, and the day the subscriptions were recovered to help you evaluate the effectiveness of recovery messaging.
Example account hold performance recovery card in the Play Console. Source: Google Internal Data.
Make sure you've set up grace periods and account hold for your apps! We've seen that developers who use both grace period and account hold see more than a 3x increase in decline recovery rate from 10% to 33%. Discover more information on grace period and account hold.
You can find the subscription retention and cancellation reports linked from the bottom of the Subscriptions page, in the Financial reports section of the Play Console. If you don't have access to financial reporting, ask your developer account owner for permission to view financial data.
We hope this new reporting gives you new insights to optimize your subscription business, and we look forward to sharing more with you at Google I/O in May.

Last year, we launched Android App Bundles and Google Play's Dynamic Delivery to introduce modular development, reduce app size and streamline the release process. Since then, we've seen developers quickly adopt this new app model in over 60,000 production apps. We've been excited to see developers experience significant app size savings and reductions in the time needed to manage each release, and have documented these benefits in case studies with Duolingo and redBus.
Thank you to everyone who took the time to give us feedback on our initial launch. We're always open to new ideas, and today, we're happy to announce some new improvements based on your suggestions:
When you adopt the Android App Bundle as the publishing format for your app, Google Play is able to optimize the installation by delivering only the language resources that match the device's system locales. If a user changes the system locale after the app is installed, Play automatically downloads the required resources.
Some developers choose to decouple the app's display language from the system locale by adding an in-app language switcher. With the latest release of the Play Core library (version 1.4.0), we're introducing a new additional languages API that makes it possible to build in-app language pickers while retaining the full benefits of smaller installs provided by using app bundles.
With the additional languages API, apps can now request the Play Store to install resources for a new language configuration on demand and immediately start using it.
The app can get a list of languages that are already installed using the SplitInstallManager#getInstalledLanguages() method.
SplitInstallManager#getInstalledLanguages()
val splitInstallManager = SplitInstallManagerFactory.create(context) val langs: Set<String> = splitInstallManager.installedLanguages
Requesting an additional language is similar to requesting an on demand module. You can do this by specifying a language in the request through SplitInstallRequest.Builder#addLanguage(java.util.Locale).
SplitInstallRequest.Builder#addLanguage(java.util.Locale)
val installRequestBuilder = SplitInstallRequest.newBuilder() installRequestBuilder.addLanguage(Locale.forLanguageTag("pl")) splitInstallManager.startInstall(installRequestBuilder.build())
The app can also monitor install success with callbacks and monitor the download state with a listener, just like when requesting an on demand module.
Remember to handle the SplitInstallSessionStatus.REQUIRES_USER_CONFIRMATION state. Please note that there was an API change in a recent Play Core release, which means you should use the new SplitInstallManager#startConfirmationDialogForResult() together with Activity#onActivityResult(). The previous method of using SplitInstallSessionState#resolutionIntent() with startIntentSender() has been deprecated.
SplitInstallSessionStatus.REQUIRES_USER_CONFIRMATION
SplitInstallManager#startConfirmationDialogForResult()
Activity#onActivityResult()
SplitInstallSessionState#resolutionIntent()
startIntentSender()
Check out the updated Play Core Library documentation for more information on how to access the newly installed language resources in your activity.
We've also updated our dynamic features sample on GitHub with the additional languages API, including how to store the user's language preference and apply it to your activities at startup.
Please note that while the additional languages API is now available to all developers, on demand modules are in a closed beta for the time being. You can experiment with on demand modules in your internal, open, and closed test tracks, while we work with our partners to make sure this feature is ready for production apps.
In Android Studio 3.3, we introduced a way to build app bundles that contain both the regular, installed version of your app as well as a Google Play Instant experience for modules marked with the dist:instant="true" attribute in their AndroidManifest.xml:
dist:instant="true"
AndroidManifest.xml
<manifest ... xmlns:dist="http://schemas.android.com/apk/distribution"> <dist:module dist:instant="true" /> ... </manifest>
Even though you could use a single project to generate the installed and instant versions of your app, up until now, developers were still required to use product flavors in order to build two separate app bundles and upload both to Play.
We're happy to announce that we have now removed this restriction. It's now possible to upload a single, unified app bundle artifact, containing modules enabled for the instant experience. This functionality is now available for everyone.
After you build an instant-enabled app bundle, upload it to any track on the Play Console, and you'll be able to select it when creating a new instant app release. This also means that the installed and instant versions of your app no longer need different version codes, which will simplify the release workflow.
You need to enable app signing by Google Play to publish your app using an Android App Bundle and automatically benefit from Dynamic Delivery optimizations. It is also a more secure way to manage your signing key, which we recommend to everyone, even if you want to keep publishing regular APKs for now.
Based on your feedback, we've revamped the sign-up flow for new apps to make it easier to initialize the key you want to use for signing your app.
Now developers can explicitly choose to upload their existing key without needing to upload a self-signed artifact first. You can also choose to start with a key generated by Google Play, so that the key used to locally sign your app bundle can become your upload key.
Read more about the new flow.
We have now added the ability to permanently uninstall dynamic feature modules that are included in your app's initial install.
This is a behavior change, which means you can now call the existing SplitInstallManager#deferredUninstall() API on modules that set onDemand="false". The module will be permanently uninstalled, even when the app is updated.
SplitInstallManager#deferredUninstall()
onDemand="false"
This opens up new possibilities for developers to further reduce the installed app size. For example, you can now uninstall a heavy sign-up module or any other onboarding content once the user completes it. If the user navigates to a section of your app that has been uninstalled, you can reinstall it using the standard on demand modules install API.
We hope you enjoy these improvements and test them out in your apps. Continue to share your feedback as we work to make these features even more useful for you!

Developers are increasingly using multiple methods to monetize their apps and games. One trend has been to reward users for a monetizable action, like watching a video, with in-game currency or other benefits. This gives users more choice in how they experience the app or game, and has been an effective way to monetize non-paying users.
To support this monetization method, Google Play is excited to announce rewarded products, a new product type now available in open beta in the Play Console.
Rewarded products make it easy for Google Play developers to increase their monetized user base. Our first rewarded product offering will be in a video format. Users can elect to watch a video advertisement and upon completion be rewarded with virtual goods or in-game currency. In the example below, the user selects "watch ad", views the video, and then is granted 100 coins.
Rewarded products can be added to any app using the Google Play Billing Library or AIDL interface with only a few additional API calls. No extra SDK integration is required. This significantly reduces the work required to implement compared to other offerings. Rewarded products are powered by AdMob technology to give access to the broad range of content from advertisers currently working with Google.
Get started with rewarded products.
For developers interested in best practices on how to diversify revenue and how rewarded products fit in, please visit us at Google's Mobile Developer day at GDC or watch via the livestream.

Earlier this year we highlighted some of Google Play's milestones and commitments in supporting the 1M+ developers on the Play Store, as well as those of you working on Android apps and games and looking to launch and grow your business on our platforms. We have been inspired and humbled by the achievements of app and game developers, building experiences that delight and help people everywhere, as some stories highlighted in #IMakeApps.
We continue to focus on helping you grow thriving businesses and building tools and resources to help you reach and engage more users in more places, whilst ensuring a safe and secure ecosystem. Looking to 2019, we are excited about all the things to come and seeing more developers adopt new features and update to Android P.
In the meantime let's share some of the 2018 highlights on Google Play and Android:
Building for the future
Along with Android P we have continued to help the Android developer ecosystem, launching Android Jetpack, the latest Android Studio, and Kotlin support. Developers are also now able to add rich and dynamic UI templates with Slices in places such as Google Search and Assistant, APIs for new screens support, and much more. Discover the latest from Android 9, API Level 28.
Smaller apps have higher conversion rates and our research shows that a large app size is a key driver of uninstalls. At I/O we launched a new publishing format, the Android App Bundle, helping developers to deliver smaller and more efficient apps with a simplified release process, and with features on demand - saving on average 35% in download size! On devices using Android M and above, app bundles can reduce app size even further, by automatically supporting uncompressed native libraries, thereby eliminating duplication on devices.
You can build app bundles in the Android Studio 3.2 stable release and in Unity 2018.3 beta, and upload larger bundles with installed APK sizes of up to 500MB without using expansion files, through an early access feature soon to be available to all developers.
Richer experiences and discovery
Discovery of your apps and games is important, so we launched Google Play Instant and increased the size limit to 10MB to enable TRY NOW on the Play Store, and removed the URL requirement for Instant apps. Android Studio 3.3 beta release, lets you publish a single app bundle and classify it or a particular module to be instant enabled (without maintaining separate code).
For game developers, Unity introduced the Google Play Instant plug-in and instant app support is built into the new Cocos Creator. Our app pre-registration program, has seen nearly 250 million app pre-registrations, helping drive app downloads through richer discovery.
Optimizing for quality and performance
Android vitals are now more actionable, with a dashboard highlighting core vitals, peer benchmarks, start-up time and permission denials vitals, anomaly detection and alerts, and linking pre-launch reports - all so that you can better optimize and prioritize issues for improved quality and performance.
There are more opportunities to get feedback and fix issues before launch. The Google Play Console expanded the functionality of automated device testing with a pre-launch report for games, and the launch of the internal and closed test tracks lets you push your app to up to 100 internal testers, before releasing them to production.
Insights for your business, now and in the long term
Metrics are critical to optimize your business and we've added new customizable tools in the Play Console, with downloadable reports to help you evaluate core metrics. Including cumulative data, 30-day rolling averages, and roll-ups for different time periods to better match the cadence of your business.
You can now configure the statistics report to show how your instant apps are performing, analyze different dimensions and identify how many install the final app on their device. The acquisition report shows users discovery journey through to conversion - with average revenue per user and retention benchmarks against similar apps. You can also find the best performing search terms for your store listing with organic breakdown - helping to optimize efforts to grow and retain a valuable audience.
Increasingly developers are adopting subscriptions as their core monetization model. The dedicated new subscriptions center means you can easily change subscription prices, offer partial refunds for in-app products and subscriptions, and also make plan changes in Play Billing Library version 1.2. Learn how to keep subscribers engaged; users can pause plans, giving you more control with order management and the cancellation survey.
Discover how to use all the new features and best practices on the Academy for App Success, our interactive free e-learning platform, offering bite-sized courses that help you make the most of Play Console and improve your app quality.
Make sure you follow @googleplaydev and sign up to our newsletter to stay ahead of all our updates in 2019! We hope these features and tools will enable us to continue a successful partnership with you in the New Year - follow our countdown for a daily highlight. From all of us at Google Play - happy holidays.

Android is fortunate to have an incredibly rich ecosystem of SDKs and libraries to help developers build great apps more efficiently. These SDKs can range from developer tools that simplify complicated feature development to end-to-end services such as analytics, attribution, engagement, etc. All of these tools can help Android developers reduce cost and ship products faster.
For the past few months, various teams at Google have been working together on new initiatives to expand the resources and support we offer for the developers of these tools. Today, SDK developers can sign up and register their SDK with us to receive updates that will keep you informed about Google Play policy changes, updates to the platform, and other useful information.
Our goal is to provide you with whatever you need to better serve your technical and business goals in helping your partners create better apps or games. Going forward we will be sharing further resources to help SDK developers, so stay tuned for more updates.
If you develop an SDK or library for Android, make sure you sign up and register your SDK to receive updates about the latest tools and information to help serve customers better. And, if you're an app developer, share this blogpost with the developers of the SDKs that you use!

In June we started adding security metadata to all apps and app updates to help verify product authenticity from Google Play. We're doing this is to help developers reach a wider audience, particularly in countries where peer-to-peer app sharing is common because of costly data plans and limited connectivity.
Now, when a user shares an app via Play-approved partner peer-to-peer apps, Play will be able to determine shared app authenticity while a device is offline, add those shared apps to a user's Play Library, and manage app updates when the device comes back online. This will give users more confidence when using Play-approved peer-to-peer app beta partners, starting today with SHAREIt and Files Go by Google. An additional integration from Xender is planned in the coming weeks. Please visit the Play Store to make sure you have the latest versions of these apps.
This also benefits you as a developer as it provides a Play-authorized offline distribution channel and, since the peer-to-peer shared app is added to your user's Play library, your app will now be eligible for app updates from Play.
No action is needed by developers or your users. This is an important step that improves the integrity of Google Play's mobile app ecosystem. Offline Play peer-to-peer sharing presents a new distribution opportunity for developers while helping more people keep their apps up to date.

Today we are kicking off Playtime, our annual global event series, hosting over 800 attendees in Berlin and San Francisco to share insights from experts around the world and the latest updates on our products. This will be followed by events in Sao Paulo, Singapore, Taipei, Seoul, and Tokyo.
At Google Play, we continue to invest in tools that make it easier for you to develop and distribute your apps to a global audience. Below are some of the exciting updates we are announcing today:
The Android App Bundle is Android's new publishing format, with which you can more easily deliver a great experience in a smaller app size. Smaller apps have higher conversion rates and our user research shows that app size is a leading motivator in driving uninstalls. With the Android App Bundle's modularization, you can also deliver features on demand, instead of at install time, further reducing the size of your app.
Thousands of app bundles are already in production, with an average size reduction of 35%. Today, we are announcing updates that offer additional reasons for you to switch to the bundle.
To learn more about the Android App Bundle, dynamic features, and all the benefits you receive from building a smaller, modular app, read our Medium post.
We've been listening to your feedback to make it easier to build instant apps, and we recently increased the size limit to 10MB to enable TRY NOW on the Play Store and removed the URL requirement. For game developers, we've partnered with Unity on a Google Play Instant plug-in and have built instant directly into the new Cocos Creator.
We’re now using the Android App Bundle to solve one of the primary pain points of building instant apps. Previously, you needed to publish both an instant app and an installable app. With Android Studio 3.2, you could publish instant-enabled bundles but you were still required to publish a primary app bundle.
Now, you don't have to maintain separate code. With the Android Studio 3.3 beta release, a developer can publish a single app bundle and classify it or a particular module to be instant enabled. The unified app bundle is the future of instant app experiences and we hope you will try it out.
Google Play Instant is now available for premium titles and pre-registration campaigns, so people can try your game before it launches and generate additional buzz. New apps and games join Google Play Instant every day, and we're excited to welcome Umiro, by Devolver Digital, and Looney Tunes World of Mayhem, by Scopely, as some of the first to take advantage of these new features.
The Play Console offers two tools to help you monitor performance and improve the quality of your apps. The pre-launch report runs your apps on real devices situated in the Firebase Test Lab and generates useful metadata to help you identify and fix issues before pushing your apps to production. Android vitals helps you track the performance and quality of your app on users' devices in the real world.
Now, we're linking them together to provide more actionable insights. Whenever a real-world crash in Android vitals is also seen during a pre-launch report execution, you'll get all the extra metadata from the pre-launch report available to you in the Android vitals dashboard so you can debug more effectively. This is also linked in both directions, so that if a crash occurs in pre-launch reports that is already happening in the real world, you'll be able to see the current impact in Android vitals which will help you better prioritize the issues highlighted by pre-launch reports.
We've made several updates to make it easier to manage your app and business with Play.
We're equally excited to launch the Academy for App Success with new interactive courses to help developers get the most out of the Play Console, understand Play policies, and utilize best practices to improve quality and increase business performance. This free new program allows you to track your learning progress with quizzes and achievements to demonstrate your expertise. Available in English today, new content and translated courses will be added soon.

Releasing a new version of your app is an exciting moment when your team's hard work finally gets into the hands of your users. However, releasing can also be challenging - you want to keep your existing users happy without introducing performance regressions or bugs. At Google I/O this year, we talked about staged releases as an essential part of how Google does app releases, allowing you to manage the inherent risks of a new release by making a new version of your app available to just a fraction of your users. You can then increase this fraction as you gain confidence that your new version works as expected. We are excited that starting today staged releases will be possible on testing tracks, as well as the production track.
We will take a closer look at how staged releases work, and how you can use them as part of your release process.
The first benefit of a staged release is that it only exposes a fraction of your users to the new version. If the new version contains a bug, only a small number of people will be inconvenienced by it. This is much safer than releasing a new version to all of your users at once.
Another benefit is that if you discover a bug, you can halt the rollout, preventing any new users from downloading that version. Instead, they will receive the previous version.
These capabilities should relieve a lot of the uncertainty of rolling out a new version. And that will allow you to do it more often. We encourage releasing versions of a server more often because it reduces the number of changes between each release, allowing you to more easily test and troubleshoot. The same principle applies to apps, though there will be a delay before most of your users upgrade to the latest version.
Let's look at a typical release process for an app with 100,000 users.
Some apps are just starting out, and although there's no QA team, it's still worth testing the app on a few different devices before releasing it. Instead of having a track for employees, the developer has added their friends and family, who can contact them if they see an issue.
When an app gets larger and uses the open testing track, it may have 5,000 testers. These testers won't give public feedback on the Play store, but will be able to give feedback to the developer directly. If this app has 1 million users, they may first release to 1%, before going to 10%, then 100%.
Once an app becomes very popular, it could have over 100,000 testers. In that case the developer is now able to do a staged release on their testing track.
Bugs happen, and if you discover a problem with your new version you may want to halt the release. This will stop users from getting the new version, either by upgrading or installing for the first time. However, those who have already got the new version will not downgrade.
If the issue was not in the app itself, but on a server that the app communicates with, it may be best to fix the issue in the server, then resume the release. Resuming it allows some fraction of your users to access the new version again. This is the same set of users that were able to download the release before it was halted.
If the issue was in the app, you will have to fix it and release a new version. Or alternatively, you may choose to rebuild the previous version with a higher version code. Then you can start a staged release to the same set of users that the previous release went to.
Staged releases are supported in v3 of the Play Console API on all tracks. Mark a release as "inProgress" and set a fraction of the population to target. For instance, to start a staged release to 5%:
{ "releases": [{ "versionCodes": ["99"], "userFraction": 0.05, "status": "inProgress" }] }
Alternatively, if you release using the UI, it will suggest a fraction.
We hope you find these features useful and take advantage of them for successful updates with Google Play. If you're interested in some of the other great tools for distributing your apps, check out the I/O 2018 sessions, and learn more about test tracks and staged updates.
