Make stronger decisions with new Google Play Console data

31 July 2019

Posted by Tom Grinsted, Product Manager, Google Play At this year’s Google I/O, we announced a slate of new features to help you take your business further with Google Play. Launching today, these changes include several improvements designed to help you make better decisions about your business by providing clearer, more actionable data. We know the right data is critical to help you improve your app performance and grow your business. That’s why we’re excited to share a major update that enables you to better measure and analyse your core statistics — the most fundamental install and uninstall metrics by user and device. We’ve also enhanced the Statistics page on the Play Console to show change over time, enable more granular configurations, and, coming soon, exclusive benchmarks for core stats!

More granular configurations are now available on the Statistics page to help you better understand your acquisition and churn. More accurate and more expansive than before, the new metrics will help you better understand your acquisition and churn. For the first time, we are including data on returning users and devices - something that we understand is critical to many developers' growth strategies. We’re also including new install methods (such as pre-installs and peer-to-peer sharing) and the ability to aggregate and dedupe over periods that suit your business needs. With these new updates, you can perform analyses that weren’t possible before, such as how many people re-installed your app last month. Here’s what else is new:

Clearer, consistent metrics definitions:

Select users or devices, acquisitions or losses
Define if you’re interested in new, returning, or all users
Measure events (for example, when someone installs) or uniques (for instance, every person who installs)

Change analysis charts automatically show the largest changes during a selected period of time for a given dimension, making it easy to see the largest contributors to your metric trends.

Saved reports allow you to configure your metrics just the way you want them, then save them for easy retrieval and common analyses.

Suggested reports help you to find interesting ways to combine your data for more valuable analysis.

And finally, all configured data can be downloaded as CSVs from within the interface.

As a result of these updates, you will notice a few changes to your metrics. Old metrics names will be deprecated, but you can configure new metrics that map to the old ones with this cheat sheet. And don’t forget to use the ‘save report’ feature on the stats page so you can easily return to any configurations you find particularly helpful!

Don’t forget to use the ‘save this report’ feature on the stats page to easily return to any configurations you find particularly helpful. Other metrics like active user and active device will see a step-change as the new definitions are more expansive and include previously under-counted data. Some new metrics map onto older ones. Where this happens, all historic data will be automatically included. But in other cases new metrics will only be generated from launch day. For unique devices or users, weekly metrics will start to appear two weeks after launch, monthly metrics once there’s a single full month’s data, and quarterly metrics once there’s a full quarter’s data. We know it’s a lot to take in at once, so make sure to bookmark the cheat sheet for helpful tips as you navigate the transition and explore your new metrics. Additionally, our Decision-Making with the Google Play Console session from Google I/O and our Play Academy training are other great resources to help you get up to speed.

Check out these updates in the Google Play Console today — we hope you find them useful. Your comments help to shape the future of Google Play, so please continue to let us know what you think.

What’s new with Fast Pair

19 July 2019

Posted by Catherina Xu (Product Manager) Last November, we released Fast Pair with the Jaybird Tarah Bluetooth headphones. Since then, we’ve engaged with dozens of OEMs, ODMs, and silicon partners to bring Fast Pair to even more devices. Last month, we held a talk at I/O announcing 10+ certified devices, support for Qualcomm’s Smart Headset Development Kit, and upcoming experiences for Fast Pair devices.

The Fast Pair team presenting at I/O 2019.

The Fast Pair team presenting at I/O 2019. Upcoming experiences Fast Pair makes pairing seamless across Android phones - this year, we are introducing additional features to improve Bluetooth device management. True Wireless Features. As True Wireless Stereo (TWS) headphones continue to gain momentum in the market and with users, it is important to build system-wide support for TWS. Later this year, TWS headsets with Fast Pair will be able to broadcast individual battery information for the case and buds. This enables features such as case open and close battery notifications and per-component battery reporting throughout the UI.

Detailed battery level notifications surfaced during “case open” for TWS headphones.

Kotlin named Breakout Project of the Year at OSCON

18 July 2019

Posted by Wojtek Kaliciński, Developer Advocate, Android

Stephanie on Stage with Kotlin on screen

Stephanie Saad Cuthbertson announces support for Kotlin during the Developer Keynote at I/O 2017. Today at OSCON (the O'Reilly Open Source Software Conference), Kotlin was awarded the Open Source Award for Breakout Project of the Year. There is no doubt to us why Kotlin received this award: it’s a fast moving (but thoughtfully developed) programming language that lets you write better code, faster. It’s great to see Kotlin continue to receive the sort of recognition as Breakout Project of the Year, building on other awards like #1 fastest growing language on Github. We’re big fans of Kotlin, and we’ve heard that you are too – feedback from you is in part why we announced support for the language over two years ago. This meant bundling the Kotlin plugin in Android Studio, along with promising to support Kotlin-built apps going forward. But there was a long way to go for many teams at Google to provide a first class experience with Kotlin in the Android ecosystem, and to convince developers that Kotlin on Android is not just a fad, but is here to stay. If you haven’t tried Kotlin yet, now is a great time to start! In fact, in the past two years, we’ve been adding a number of new features and upgrades to the Kotlin for Android experience, including:

Android Jetpack APIs now have first class support for Kotlin Coroutines, transforming the way we do async operations on Android. This includes Room, LiveData, ViewModels, WorkManager and more coming in the future.

Many Jetpack libraries have Kotlin extension libraries (KTX) to make using them even more fluent with Kotlin.

The compilation toolchain has received many improvements for Kotlin, including compiler enhancements, incremental annotation processing with KAPT, and Kotlin-specific R8 optimizations.

All of our documentation pages now contain Kotlin code snippets, so you can easily compare how our APIs work in both languages.

Most of our flagship samples are also written in Kotlin (including IOSched, Plaid, Sunflower and many more), along with any new samples that we make in the future.

We've added a language switcher to our API reference pages, so you can have a Kotlin view of the AndroidX library and the Android framework.

We doubled down on providing guidance to developers and teams who want to switch to Kotlin on our developers.android.com/kotlin pages.

Our Developer Relations engineers are posting real life examples and guides on integrating Kotlin in your apps on our Medium publication, such as the great intro to Coroutines on Android series and many more.

If you prefer to learn Kotlin in person, you can join one of the many Kotlin/Everywhere events happening around the world. If you are an organizer in a local developer community, consider signing up to host your own event!
This initiative is a cooperation between JetBrains and Google.

For those of you who don't have access to in-person training, we added a new, free course on Udacity for Developing Android apps in Kotlin. Our Kotlin Bootcamp for Programmers course is still available as well!

We have worked with many external partners to gather feedback and learn about their experiences with Kotlin, such as this case study with Square.

And lastly, we've enabled Kotlin as a supported language for Android app teams at Google. We're already seeing adoption in apps such as Google Home, Google Drive, Android System UI, Nest, with many more to follow.

The road to fully supporting Kotlin on Android was not always easy, but it was truly rewarding seeing Kotlin adoption among professional Android developers rise from a handful of early adopters to around 50% since the original announcement! We were confident when we announced earlier this year at Google I/O 2019 that Android is going increasingly Kotlin-first, opening up the possibility for APIs built specifically around Kotlin and for Kotlin users, starting with the new, declarative UI toolkit - Jetpack Compose (still in early development). We want to congratulate JetBrains, our partners through the Kotlin Foundation and creators of Kotlin, on receiving the OSCON Open Source Award today. It shows how disruptive and transformative Kotlin has been, and not just for the Android developer community, but beyond. We know one thing: on Android, Kotlin is here to stay.

What’s new for text in Android Q

11 July 2019

Posted by Florina Muntenescu, Android Developer Advocate Displaying text is an important task in most apps, so in Android Q we're continuing to introduce new features to support your needs and improve performance. We disabled hyphenation by default, enabled creating a typeface using multiple fonts or font families, exposed the list of fonts installed on the device, and improved some of the most-used text styling APIs. Hyphenation is off by default in Android Q and AppCompat v1.1.0 Our performance tests showed that when hyphenation is enabled, up to 70% of the time spent on measuring text is on hyphenation.

pie chart showing CPU of time spent making StaticLayout: Hyphenation takes up to 70% of the time spent measuring text, 30% Other text

Hyphenation takes up to 70% of the time spent measuring textGiven that hyphenation often isn’t needed for all TextViews in an app, and because of the impact on performance, we decided to turn hyphenation off by default in Android Q and AppCompat v1.1.0. If you want to use hyphenation, you need to manually turn it on in your app by setting the hyphenation frequency to normal. You can set this in multiple ways: As a TextAppearance attribute in styles.xml: <style name="MyTextAppearance" parent="TextAppearance.AppCompat"> <item name="android:hyphenationFrequency">normal</item> </style> As a TextView attribute: <TextView android:hyphenationFrequency="normal" /> Directly in code: textView.hyphenationFrequency = Layout.HYPHENATION_FREQUENCY_NORMAL Find out more about how hyphenation works from this talk at Android Dev Summit 2018. Use multiple custom fonts in the same TextView Consider a button which mixes a custom font (Lato in this example) with an icon font:

Secure Checkout Button with lock icon, icon and latin fonts

Button with icon and Latin fonts The Button class accepts only a single instance of a typeface to be set on the text. Pre-Android Q, you can create a Typeface using a single font family. Android Q enables the creation of a typeface from multiple font families with a new API, Typeface.CustomFallbackBuilder, that allows adding up to 64 font families per typeface. Our icon font example can be implemented like this: button.typeface = Typeface.CustomFallbackBuilder( // add the Latin font FontFamily.Builder( Font.Builder(assets, "lato.ttf").build() ).build() ).addCustomFallback( // add the icon font FontFamily.Builder( Font.Builder(assets, "icon_font.ttf").build() ).build() ).build() When creating the font family, make sure you don’t put fonts that belong to different families in the same font family object nor the same style fonts into the same font family. For example, putting Lato, Kosugi, and Material into the same font family creates an invalid configuration, as does putting two bold fonts into the same font family. To define the general font family (serif, sans-serif, or monospace) to be used when text is rendered using system fonts, use the setSystemFallback() method to set the system fallback font: Typeface.CustomFallbackBuilder( FontFamily.Builder( ... ).build() ).setSystemFallback("sans-serif") .build() Text styling API updates Android Q brings several updates to different text styling APIs: Improved support for variable fonts TextAppearance now supports the fontVariationSettings attribute: <style name="MyTextAppearance" parent="TextAppearance.AppCompat"> <item name="android:fontVariationSettings">...</item> </style> The fontVariationSettings attribute can be set directly on the TextView in Android Q and in AppCompatTextView: <TextView ... app:fontVariationSettings="..." /> Improved spans APIs TextAppearanceSpan now supports typeface, shadow settings, fontFeatureSettings and fontVariationSettings. LineBackgroundSpan and LineHeightSpan interfaces now have standard implementations: LineBackgroundSpan.Standard and LineHeightSpan.Standard. Access system fonts With more than 100 languages supported by Android, and with different fonts supporting different character sets, knowing which system font can render a given character is not trivial. Apps doing their own text rendering such as games, document viewers, or browsers need this information. In Android Q, you can retrieve the supported system font for a string with the FontMatcher NDK API.

System fonts that can render this text Let’s consider the above search string. The FontMatcher API returns us the font object and length. A simplified pseudocode example looks like this: // font = NotoSansCJK-Regular.ttc // length = 2 auto[font, length] = AFontMatcher_match("たすく a.k.a. のな"); // font = Roboto-Regular.ttf // length = 8 auto[font, length] = AFontMatcher_match(" a.k.a. のな"); // font = NotoSansCJK-Regular.ttc // length = 2 auto[font, length] = AFontMatcher_match("のな"); The FontMatcher API never returns nullptr:

If no font supports the given string, a font for Tofu (󟿽), the missing glyph symbol, is returned.

If no exact style is supported, a font with the closest, most similar style is returned.

If you want to get all available system fonts, you can do this with a new font enumeration API. In Java, you can use SystemFonts.getAvailableFonts, or in the NDK, you can use ASystemFontIterator. The results of the font enumeration are changed only by a system update, so you should cache them. Font updatesNew Myanmar font Android added a new Myanmar font to Android Q that is Unicode-compliant and capable of rendering both Unicode and non-Unicode Burmese (commonly known as Zawgyi), right out of the box. This means starting in Android Q, Android makes it easier for users to switch to Unicode: a user can now use a Unicode font to read Unicode and non-Unicode text for the first time. Android also added new requirements to the Android ecosystem CDD that takes a stronger stance in requiring Unicode, including a new subtag "Qaag" which OEMs should use as a locale designating non-Unicode Burmese. All of these changes should make developers’ life easier in the long term, as reduced ecosystem fragmentation makes it easier to develop for our 50M users in Myanmar. New emojis

Emojis in Android Q Say Hello to your new emoji friends! The latest update includes a number of disability-focused emojis, multi-racial couples, as well as a few cute animals and household objects. See the latest and greatest in Gboard on your Android Q device of choice. Text plays an important role in a vast majority of apps, so we’re continuing to invest in improving text API features and performance. Learn more about the new APIs in Android Q along with best practices when working with text in our Google I/O 2019 talk:

Android Q Beta 5 Update

10 July 2019

Posted by Dave Burke, VP of Engineering

Android Q Beta 5 launches today! Today we're rolling out Beta 5, bringing Android Q Beta very close to the system behaviors you'll see in the final release. Developer APIs were already finalized in the previous update. So, now is the time to test your apps for compatibility and make sure they are ready! You can get Beta 5 today on Pixel devices by enrolling here. If you're already enrolled and received Beta 4 on your Pixel device, you'll automatically get the update to Beta 5. Partners participating in the Android Q Beta program will also be updating their devices to Beta 5 over the coming weeks. To get started with Android Q Beta, visit developer.android.com/preview. What’s in Beta 5? The Beta 5 update includes the latest Android Q system images for Pixel and Android jEmulator, along with the final Android Q developer APIs (API level 29), the official API 29 SDK, and updated build tools for Android Studio. These give you everything you need to test your apps on Android Q and build with Android Q features. Gestural navigation updates As we talked about at Google I/O, we’ve been working closely with device-maker partners to ensure a standardized Android gestural navigation for users and developers. Gestural navigation lets apps use the full screen for content while minimizing the visible system chrome and navigation – which is particularly important on today’s edge-to-edge screens. In Beta 5 we’re continuing to improve and polish based on your feedback and we wanted to provide an update on a few key areas. We’ve introduced a swipe gesture from either corner to get to the Assistant - you’ll notice indicators in the bottom corners that we’re continuing to tune. For apps using a navigation drawer, we’ve added a peek behavior when users have grabbed the drawer to indicate that a swipe will bring in the navigation drawer. This works for all versions of DrawerLayout, with DrawerLayout 1.1.0-alpha02 optimized for the best experience. Custom launchers are another area where we’ve heard feedback and we’re continuing to work on issues, particularly with stability and Recents. Starting in Beta 6, we’ll switch users to 3-button navigation when they are using a custom launcher by default. We’ll address the remaining issues in a post-launch update allowing all users to switch to gestural navigation. Meanwhile, please continue to give us your feedback. Get your apps ready for Android Q! With the consumer release coming soon, it’s highest priority for all Android developers to update your current apps for compatibility as soon as possible. Here’s how to do it:

Install your app on Android Q: Install your current app from Google Play onto an Android Q Beta device or emulator, then test. Your app should run and look great and run well, with full functionality. handle all of the Android Q behavior changes properly. Watch for impacts from privacy changes, gestural navigation, changes to dynamic linker paths for Bionic libraries, and others.

Test with the Android Q privacy features, such as the new location permissions, restrictions on background activity starts, changes to data and identifiers, and others. See the privacy checklist to get started, and review the behavior changes doc for more areas to test.

Test for uses of restricted non-SDK interfaces and move to public SDK or NDK equivalents instead. Details here.

Test the libraries and SDKs in your app: Make sure they work as expected on Android Q and follow best practices for privacy, performance, UX, data handling, and permissions. If you find an issue, try updating to the latest version of the SDK, or reach out to the SDK developer for help. You can also report SDK compatibility issues here.

Update and publish your compatible app: When you’ve finished your testing and made any updates, we recommend publishing your compatible app right away. This lets Android Beta users test the app now, and helps you deliver a smooth transition to users as they update to Android Q.

We realize that supporting these changes is an investment for you too, and we're working to minimize the impact on your apps and be responsive to your input as we move toward the final release. Enhance your app with Android Q features and APIs Next, when you're ready, dive into Android Q and learn about the new features and APIs that you can use. Here are some of the top features to get started with. We recommend these for every app:

Dark Theme: Ensure a consistent experience for users who enable system-wide dark theme by adding a Dark Theme or enabling Force Dark.

Support gestural navigation in your app by going edge-to-edge and making sure your custom gestures are complementary to the system navigation gestures.

Optimize for foldables: Deliver seamless, edge-to-edge experiences on today’s innovative devices by optimizing for foldables.

We recommend these if relevant for your app:

More interactive notifications: If your notifications include messages, enable suggested replies and actions in notifications to engage users and let them take action instantly.

Better biometrics: If you use biometric auth, move to BiometricPrompt, the preferred way to support fingerprint auth on modern devices.

Enriched recording: To support captioning or gameplay recording, enable audio playback capture -- it’s a great way to reach more users and make your app more accessible.

Better codecs: For media apps, try AV1 for video streaming and HDR10+ for high dynamic range video. For speech and music streaming, you can use Opus encoding, and for musicians, a native MIDI API is available.

Better networking APIs: If your app manages IoT devices over Wi-Fi, try the new network connection APIs for functions like configuring, downloading, or printing.

These are just a few of the many new features and APIs in Android Q -- to see them all, visit the Android Q Beta site for developers. Publish your app updates to Google Play As soon as you're ready, publish your APK updates to Google Play that are compiled against, or optionally targeting, API 29. To make sure that your updated app runs well on Android Q as well as older versions, try using Google Play testing tracks. With tracks you can safely get early feedback from a small group of users -- including Beta 5 users — and then do a staged rollout to production. How do I get Beta 5? It’s easy! Just enroll any supported Pixel device here to get the update over-the-air. If you're already enrolled, you'll receive the update soon and no action is needed on your part. Downloadable system images are also available here. Partners who are participating in the Android Q Beta program will be updating their devices over the coming weeks. See android.com/beta for details. To get started developing, download the official API 29 SDK and tools into the stable release of Android Studio 3.4, or for the latest Android Q support update to Android Studio 3.5 Beta. Then follow these instructions to configure your environment, and see the release notes for known issues. There will be one more Beta release before the consumer launch later this quarter. Please continue to share your feedback and requests -- you can use our hotlists for filing platform issues (including privacy and behavior changes), app compatibility issues, and third-party SDK issues. Also, the Android engineering team will host a Reddit AMA on r/androiddev to answer your technical questions about Android Q later this month. Look out for an announcement on r/androiddev with details in the coming weeks. We look forward to addressing your questions!

Capturing Audio in Android Q

03 July 2019

Posted by Don Turner, Developer Advocate for Android Media

In Android Q there's a new API which allows applications to capture the audio of other applications. It's called the AudioPlaybackCapture API and it enables some important use cases for easier content sharing and accessibility. Some examples include:

Live captioning - allowing the audio content of the currently playing app to be captioned or translated in real time. In fact, the Live Caption feature shown at I/O this year is a client of this API. Live captioning allows your users to engage with audible content even when it's impossible or inconvenient to do so, such as listening in a public place without headphones.

Game recording and streaming - In-game sounds can be recorded and streamed to live audiences, helping to increase the social reach of game content.

There may be some situations where a developer wishes to disallow the capture of their app's audio. This article explains how audio capture works for users and how developers can disallow their app's audio from being captured if they need to. What does the user see? In order to capture the audio of other apps the user must grant the record audio permission to the app doing the capturing.

AUDIO_RECORD permissions dialog Additionally, before a capture session can be started the capturing app must call MediaProjectionManager.createScreenCaptureIntent(). This will display the following dialog to the user:

Screen capture intent dialog The user must tap "Start now" in order for a capturing session to be started. This will allow both video and audio to be captured.

Cast icon showing red in status bar During a capture session the cast icon is shown in red in the status bar. Can my app's audio be captured? Whether your app's audio can be captured by default depends on your target API. Here's a table which summarizes the default behaviour:

Target API	Third party apps can capture your app's audio by default?	System apps and components can capture your app's audio by default?
28 and below	No, the app needs to explicitly opt-in	Yes for audio with usage type MEDIA, GAME and UNKNOWN
29	Yes for audio with usage type MEDIA, GAME and UNKNOWN	Yes for audio with usage type MEDIA, GAME and UNKNOWN

Disallowing capture by third party apps There may be situations where an app wishes to disallow its audio from being captured by other apps. This could be because the audio contains:

sensitive information - such as private voice recordings.

copyrighted material - such as copyrighted music or audio from movies and TV shows.

An app's audio capturing policy can be set either for all audio or for each individual audio player. Disallowing capture of all audio by third party apps To disallow capture of all audio by third party apps you can do either of the following:

Add the following to your AndroidManifest.xml

<application

...

android:allowAudioPlaybackCapture="false"/>

Programmatically disable capture by running the following code prior to playing audio AudioManager.setAllowedCapturePolicy(ALLOW_CAPTURE_BY_SYSTEM)

Disallowing capture on a per player basis by third party apps To disallow capture for an individual player you can set the capture policy for the audio player when it is built by calling: AudioAttributes.Builder.setAllowedCapturePolicy(ALLOW_CAPTURE_BY_SYSTEM) This approach may be useful if your app plays content with differing licenses. For example, both copyrighted and royalty-free content. Disallowing capture by system apps and components By default system apps and components are allowed to capture an app's audio if its usage is MEDIA, GAME and UNKNOWN, as this enables important accessibility use cases, such as live captioning. In rare cases where a developer wishes to disallow audio capture for system apps as well they can do so in a similar way to the approach for third party apps. Note that this will also disallow capture by third party apps. Disallowing capture of all audio This can only be done programmatically by running the following code before any audio is played: AudioManager.setAllowedCapturePolicy(ALLOW_CAPTURE_BY_NONE) Disallowing capture on a per player basis To disallow capture for an individual player you can set the capture policy for the audio player when it is built: AudioAttributes.Builder.setAllowedCapturePolicy(ALLOW_CAPTURE_BY_NONE) What next? If your app is targeting API 28 or below and you would like to enable audio capture add android:allowAudioPlaybackCapture="true" to your app's manifest.xml. If you would like to disallow some or all of your audio from being captured then update your app according to the instructions above. For more information check out the Audio Playback Capture API documentation.

Indie Games Showcase from Google Play - meet the winners!

02 July 2019

Posted by Patricia Correa, Director, Developer MarketingWe just wrapped up the Indie Games Showcase in Europe, Japan & South Korea! Back in March we started our search for some of the newest and most creative indie titles from these regions.
