Continuing to boost developer success on Google Play

Posted by Purnima Kochikar, VP of Play Partnerships

As we highlighted in March, our mission is to help all developers succeed and build sustainable businesses. Last month at Google I/O, we built on this by announcing updates aimed at ‍helping more users discover your apps and games, opening enrollment for the new 15% service fee tier, and more.

But we’re always looking for ways to help developers of all types succeed on Google Play, and today we have even more to share.

Investing in better cross-device experiences

Users expect compelling content no matter what device they’re on. With our recent launch of Entertainment Space for tablets, the announcement that Samsung watches are coming to Wear OS, the upgraded Android Auto platform, and a new discovery experience on Google TV, there’s more opportunity for developers to engage their users than ever.

On Play, we are excited to help developers scale their services beyond mobile and across all the form factors that are important to users. We've long offered programs to help you build innovative experiences and today, we are opening our Play Media Experience Program globally to enable even more developers to invest in best-in-class media experiences across devices, including:

  • Video - high quality video content for the living room; requires integrations with Android TV, Google TV, and Google Cast
  • Audio - subscription music and audio services that work everywhere; requires integrations with Wear OS, Android Auto, Android TV, and Google Cast
  • Books - compelling reading experience on larger screens; optimized experience on tablets, foldables, and integration with the new Entertainment Space.

Through these integrations, we enable new discovery and re-engagement opportunities for developers to accelerate their overall growth on Play and offer a service fee of 15% during the program term, all to help developers deliver premium experiences.

Developers can review program guidelines and express interest now and we’ll follow up with more information if you are eligible. The Play Media Experience Program joins our many other resources for developers, including, Subscribe with Google for news publishers, our existing enterprise programs, and our many other initiatives like Play Points and Play Pass that help us continually improve our offerings to users and meet the needs of developers.

New updates ahead for game developers

Register now for the digital Google for Games Developer Summit on July 12 and 13 to hear the latest product updates from across Google. We’ll have over 20 sessions from Android, Play, Cloud, Firebase, and ads to help you build better games and reach your users.

As always we will continue to listen to your feedback and we look forward to looking for even more ways to support your business at every stage on Google Play.

Improve your app mileage with Android for Cars App library

Posted by Madan Ankapura, Product Manager

In April, we announced our first version of the Android for Cars App Library as part of Jetpack, reaching a milestone to let developers publish their navigation, parking, charging apps on the Google Play Store.

Build sophisticated search features with AppSearch

Posted by Dan Saadati, Software Engineer, and Hanaa ElAzizi, Technical Program Manager

Introducing AppSearch in Jetpack, now available in Alpha. AppSearch is an on-device search library which provides high performance and feature-rich full-text search functionality.

With AppSearch, your application can:

  • Offer offline search capabilities as AppSearch data lives completely on-device.
  • Have lower latency for indexing and querying over large data sets compared to SQLite, due to lower I/O use.
  • Provide relevant search results with built-in scoring strategies, such as BM25F.
  • Provide multi-language support for text search.
  • Issue a single query to retrieve data of multiple data types compared to issuing one query per data type in SQLite.

In AppSearch, you need to create a database to manage structured data, called “documents”. You then define what the structure looks like using “schema types”. For instance, you can model a message as a schema type with properties such as subject, body, and sender.

Documents that are added to your database can be queried over. Querying for “body:fruit” will retrieve all documents with the term “fruit” in the “body” of the Message.

To showcase how an application might integrate AppSearch, take this example of a grocery list application. Users can add grocery items to their list to refer to when they’re out shopping. Since AppSearch offers multi-language support by default, users can also include specialty ingredients for their global recipes. Users add an item by typing in the name and selecting the store and category it belongs to. The user can search by item name and select filters for store or category. AppSearch will return matching results for the application to display.

Ready to dive into using AppSearch to enrich your app’s search functionality? Check out the AppSearch guide and start using it in your app.

Help us make the library better: give us feedback on things you like, and issues or features you would like to see. If you find a bug or issue, feel free to file an issue.

Android 12 Beta 2 Update

Posted by Dave Burke, VP of Engineering

Android 12 logo

Just a few weeks ago at Google I/O we unwrapped the first beta of Android 12, focusing on a new UI that adapts to you, improved performance, and privacy and security at the core. For developers, Android 12 gives you better tools to build delightful experiences for people on phones, laptops, tablets, wearables, TVs, and cars.

Today we’re releasing the second Beta of Android 12 for you to try. Beta 2 adds new privacy features like the Privacy Dashboard and continues our work of refining the release.

End-to-end there’s a lot for developers in Android 12 - from the redesigned UI and app widgets, to rich haptics, improved video and image quality, privacy features like approximate location, and much more. For a quick look at related Google I/O sessions, see Android 12 at Google I/O later in the post.

You can get Beta 2 today on your Pixel device by enrolling here for over-the-air updates, and if you previously enrolled for Beta 1, you’ll automatically get today’s update. Android 12 Beta is also available on select devices from several of our partners - learn more at android.com/beta.

Visit the Android 12 developer site for details on how to get started.

What’s new in Beta 2?

Beta 2 includes several of the new privacy features we talked about at Google I/O, as well as various feature updates to improve functionality, stability, and performance. Here are a few highlights.

Privacy Dashboard - We’ve added a Privacy Dashboard to give users better visibility over the data that apps are accessing. The dashboard offers a simple and clear timeline view of all recent app accesses to microphone, camera, and location. Users can also request details from an app on why it has accessed sensitive data, and developers can provide this information in an activity by handling a new system intent, ACTION_VIEW_PERMISSION_USAGE_FOR_PERIOD. We recommend that apps take advantage of this intent to proactively help users understand accesses in the given time period. To help you track these accesses in your code and any third-party libraries, we recommend using the Data Auditing APIs. More here.

Mic and camera indicators - We’ve added indicators to the status bar to let users know when apps are using the device camera or microphone. Users can go to Quick Settings to see which apps are accessing their camera or microphone data and manage permissions if needed. For developers, we recommend reviewing your app’s uses of the microphone and camera and removing any that users would not expect. More here.

Microphone & camera toggles - We’ve added Quick Settings toggles on supported devices that make it easy for users to instantly disable app access to the microphone and camera. When the toggles are turned off, an app accessing these sensors will receive blank camera and audio feeds, and the system handles notifying the user to enable access to use the app’s features. Developers can use a new API, SensorPrivacyManager, to check whether toggles are supported on the device. The microphone and camera controls apply to all apps regardless of their platform targeting. More here.

Clipboard read notification - To give users more transparency on when apps are reading from the clipboard, Android 12 now displays a toast at the bottom of the screen each time an app calls getPrimaryClip(). Android won’t show the toast if the clipboard was copied from the same app. We recommend minimizing your app’s reads from the clipboard, and making sure that you only access the clipboard when it will be expected by users. More here.

More intuitive connectivity experience - To help users understand and manage their network connections better, we’re introducing a simpler and more intuitive connectivity experience across the Status Bar, Quick Settings, and Settings. The new Internet Panel helps users switch between their Internet providers and troubleshoot network connectivity issues more easily. Let us know what you think!

Android 12 at Google I/O

At Google I/O we talked about everything that’s new in Android for developers - from Android 12 to Modern Android Development tools, new form factors like Wear and foldables, and Google Play. Here are the top 3 things to know about Android 12 at Google I/O.

#1 A new UI for Android - Android 12 brings the biggest design change in Android's history. We rethought the entire experience, from the colors to the shapes, light and motion, making Android 12 more expressive, dynamic, and personal, under a single design language called Material You.

#2 Performance - With Android 12, we made significant and deep investments in performance, from foundational system performance and battery life to foreground service changes, media quality and performance, and new tools to optimize apps.

#3 Privacy and security - In Android 12 we’re continuing to give users more transparency and control while keeping their devices and data secure.

For an overview of Android 12 for developers, watch this year’s What's new in Android talk, and check out Top 12 tips to get ready for Android 12 for an overview of where to test your app for compatibility. The full list of Android content at Google I/O is here.

App compatibility

With more early-adopter users and developers getting Android 12 beta on Pixel and other devices, now is the time to make sure your apps are ready!

To test your app for compatibility, install the published version from Google Play or other source onto a device or emulator running Android 12 Beta. Work through all of the app’s flows and watch for functional or UI issues. Review the behavior changes to focus your testing. There’s no need to change your app’s targetSdkVersion at this time, so when you’ve resolved any issues, publish an update as soon as possible for your Android 12 Beta users.

timeline for Android 12

With Beta 2, Android 12 is closing in on Platform Stability in August 2021. Starting then, app-facing system behaviors, SDK/NDK APIs, and non-SDK lists will be finalized. At that time, you should finish up your final compatibility testing and release a fully compatible version of your app, SDK, or library. More on the timeline for developers is here.

Get started with Android 12!

Today’s Beta release has everything you need to try the latest Android 12 features, test your apps, and give us feedback. Just enroll any supported Pixel device to get the update over-the-air. To get started developing, set up the Android 12 SDK.

You can also get Android 12 Beta 2 on devices from some of our top device-maker partners like Sharp. Visit android.com/beta to see the full list of partners participating in Android 12 Beta. For even broader testing, you can try Android 12 Beta on Android GSI images, and if you don’t have a device you can test on the Android Emulator.

Beta 2 is also available for Android TV, so you can check out the latest TV features and test your apps on the all-new Google TV experience. Try it out with the ADT-3 developer kit. More here.

Android @ Google I/O: Recapping building across devices

Posted by The Android Team

At Google I/O this year, we talked about how your app can take advantage of Android's different screens, both large and small. But if you missed the show, here are the top things you should know:

Tablets, Foldables, and Large Screens

It's more important than ever to design your app to work well on large screens — including tablets, foldables, and Chrome OS laptops. There are already over 250 million large screen Android devices in use today. Meanwhile, new foldable devices are making it easier for users to multitask, and opening up new experiences like tabletop mode for hands-free activities. See this example of Disney+ using tabletop mode on the Samsung Galaxy Z Fold2.

foldables image

Fortunately, it's also easier than ever to design apps which seamlessly scale to adapt to any device size — including dynamically resizing on Chrome OS and foldable devices, taking advantage of Jetpack Compose or ConstraintLayout to build responsive layouts. We also studied how people interact with large screens, like where their fingers are placed, and we’re giving you APIs and Tools to make that experience easier:

We’ve also made updates to the Android platform, Chrome OS, and Jetpack WindowManager, so apps just work better by default. For example, many UI elements now have default Max Width values to make sure they look better on large screens, while changes to the Display API ensure that existing apps continue to render correctly on foldables even if they aren't using WindowManager to query window metrics.

Learn more about how we are helping you build for large screens with these I/O sessions:

For even more details, check out the what's new in foldables, tablets, and large screens article, or read the case study on how Google Duo sees increased engagement and improved ratings.

Wear OS

We announced our biggest update yet to the Wear platform, with new features, APIs and tools to help developers create beautiful, high quality wearable experiences.

There are new Jetpack APIs to help you streamline your development. The Tiles library gives users fast, predictable access to the information and actions they rely on most. Another notable addition is the Ongoing Activities API, which enables you to let your users return to your app after they’ve navigated away (to start some other task such as music playback). Both of these libraries are currently in alpha.

We also released a new set of APIs for health and fitness that act as an intermediary to the sensors and related algorithms on the device to provide apps with high-quality data related to activity, exercise, and health. The alpha of the Health Services platform is available to use today.

Download Android Studio Arctic Fox Beta to try out a developer preview of the new Wear system image and start preparing your apps for the new platform. Check out the I/O sessions below to learn more about these announcements:

You can also read more details on the latest changes to Wear, as well as learn about how Spotify is building on Wear.

Android TV

Android TV OS now has over 80 million monthly active devices, with 80% growth in the US and is at the heart of the Google TV experience launched last fall. Meanwhile, Google TV itself can be found on streaming devices like the Chromecast with Google TV, smart TVs from Sony, and as an app on Android devices — including tablets.

This year at I/O, we announced several new tools and features to make developing for Android TV OS easier:

  • Cast Connect with Stream Transfer allows moving existing audio and video streams between cast devices, while Stream Expansion allows playing audio on multiple devices simultaneously.
  • We are now making our first Google TV Emulator available alongside the Android TV emulator, both running on Android 11.
  • Firebase Test Lab is adding Android TV support, letting you test your app in the cloud across hundreds or thousands of virtual devices. Physical Devices will be coming soon.
  • We are making the Android 12 Beta 1 available for TV on ADT-3 today.

These releases make it easier to build and test applications across a range of device configurations, while bringing the latest Android 12, Googler Assistant, and Cast features to the TV. To learn more, watch the What's new in Android TV and Google TV session from I/O.

Android for Cars

Android Auto allows applications to connect with the infotainment displays built into many modern vehicles. To make this even easier we recently made the Android for Cars App Library available as part of Jetpack. This library allows navigation, EV charging, and parking apps to integrate directly with compatible cars.

We plan to expand to more app categories in the future, so if you’re expressing interest in bringing your app to Android Auto please fill out this interest form. You can also get started with the Android for Cars App Library today, by visiting g.co/androidforcars. Watch the What’s new with Android for Cars session from I/O for even more detail, or the accompanying What's new with Android for Cars blog post.

Tell me about your journey to becoming an Android Developer and how you got started.

My journey in becoming an Android Developer started in 2015, during my final year of engineering school in Paris. My friends and I created a startup that allows you to easily create social events. As an Android user, my mission was to create an Android app. The experience made me excited to build apps, brainstorm products, engage with users; understand metrics and the process of innovation.

Initially, learning to code in Android was a tool to help reach my goal: to create a product that would be used by the largest audience possible. My passion to develop on Android, however, gave me the patience and perseverance needed to self-improve and become an expert. I realized the key to success is consistency: that step-by-step progress allows big achievements.

Although I entered the Android field by chance, I feel very grateful to have specialized in a technology which allows me to reach the huge Android marketplace, with an incredibly diverse user base. I believe when you love working on products, specifically in B2C business, being a client software engineer is very appealing. You’re in a unique position where you can interact with customers, as well as product, design, backend, and data scientists.

After receiving my Master's, I took intensive Java training and worked at a chic software consultant engineering company, in the famous avenue Les Champs & Elysee. Whilst I learned a lot from this experience, I wanted to give entrepreneurship another shot so I left Paris for San Francisco and opened a startup called Tribe, with friends. Tribe consisted of 10 talented French entrepreneurs aiming to re-invent the video chat messaging app. This is where I started to specialize in live video streaming technology and - more precisely - WebRTC.

Tribe gathered thousands of upvotes on Product Hunt and was awarded several times by worldwide institutions including Google and Time, and also featured in various international publications such as TechCrunch, Business Insider, and more! Our hard work and determination led us to be backed by Sequoia and Kleiner Perkins Capital. This experience was utterly unique: we all were working and living in the same house with a common goal to create an everlasting impact! With this experience, I learned the power of collective intelligence; that people will go far in learning how to work with each other.

After three years of entrepreneurship, we made the hard decision to discontinue Tribe and I decided to return to Europe. During this time, Twitter contacted me for my skills in live video streaming technology. As my passion for social science, politics and economy was growing, Twitter interested me greatly as it’s the only social media platform that enables public conversation; its main focus is to highlight and discuss what’s happening in the world. Considering myself a “citizen of the word”, I found that its purpose resonated strongly with me: a global inclusive platform, where everyone has a voice. What I love the most about working at Twitter is that Twitter has a unique position by being relatively small as a company, but has a huge impact on society.

My Twitter journey began working on a live video streaming product on Periscope, called Hydra. After sunsetting Periscope, my team began to wonder what to do with the live streaming publishing pipeline technology that we built. We then partook in a brainstorm session, concluding that audio was an under-used and under-valued media that could enhance and drive Twitter’s public conversation.

We started small with one developer on each platform, reaping the benefits of being a small team that could iterate and move fast. Today, the team has vastly expanded and I am proudly operating as the Android Space Tech Lead. Twitter Space has now become one of the company's top priorities: we have only just started to witness the powerful impact of live audio, with a social media network set to drastically change social behavior.

What’s one shortcut, tip, or hack you can’t live without?

Learning how to use Android Studio property is a must! There are many hidden tools in Android Studio that can help developer velocity.

What's the one piece of advice you wish someone would have given you when you started on your journey?

1- Learn English fluently

2- Don’t be afraid to make mistakes

3- Work on something you love!

Tell me about your journey to becoming an Android Developer and how you got started.

That was a story from a long time ago. I was learning Java when I got into college in 2008. One day in 2010, I was just browsing the Internet as usual, and found a course talking about how to learn Android development. That was the first time I heard about Android. It was a brand-new mobile system for me, besides, Java just happened to be the designated programming language for it. I was very interested at that time, and made a decision to get onboard.

Now I am an Android GDE and work for Microsoft where I continue my Android development journey. I also published a book in 2014 which is the best-selling Android programming book in China. I feel so fortunate to have made that decision in 2010.

What’s one shortcut, tip, or hack you can’t live without?

I really do have one. Use Ctrl+W to expand selection in Android Studio.

gif of Ctrl+W in use

This is absolutely my favorite one. I often have some conditions where I need to copy some part of code to somewhere else. Dragging to select is the last thing I want to do. With Ctrl+W, I can always select the part of the code just as I wanted quickly and conveniently. Thanks to Google and JetBrains.

What's the one piece of advice you wish someone would have given you when you started on your journey?

I joined the Microsoft Edge mobile team recently. It is an Android project, but most of the code was written in C++. I was struggling with it at first, because I had never written C++ code before.

Now, I have started learning C++ programming from scratch. It is still a happy journey to learn something new. But I wish someone would have given me this advice when I started with Android: C++ is also an important part of Android development.

Tell me about your journey to becoming an Android Developer and how you got started.

I started my career after university in Silicon Valley as a Java backend engineer and was curious about mobile, and wanted to give it a try. At my first job, I was working at Intuit on Mint and asked the mobile PM if I could help out with either the iOS or Android app.

At the time I was an iOS user so I was leaning towards iOS, but upon research I saw that Android was dominating in the global market. Since I already knew Java, the barrier of entry was lower.

I then joined the Mint mobile team and learned Android development on the job, converted to being an Android user and never looked back :-). Since then I’ve led both Android and cross-functional teams, and enjoy collaborating across functions to deliver great mobile experiences to users.

What’s one shortcut, tip, or hack you can’t live without?

The “Design View” in Android Studio where I can quickly see what screens look like in night mode, landscape, and small devices while developing screens, helps save time.

In the Compose world, Interactive Mode and Deploy Preview are quite handy in quickly iterating over them as well. I am looking forward to performance improvements here.

A second tip would be to use the Accessibility Scanner to help identify accessibility improvements. This is another great tool that can give you quick wins!

What's the one piece of advice you wish someone would have given you when you started on your journey?

To lean into the Android community. I relied solely on Android documentation to learn when I started, and didn’t know about the supportive community and content that surrounds it until later!

Reading blog posts, watching/giving talks, and connecting with other developers accelerated my learning, and I can’t recommend it enough.

Tell me about your journey to becoming an Android Developer and how you got started.

My Android journey began with a G1, the very first commercialized Android smartphone. It had a built-in keyboard, a joystick and hard buttons, to me it was amazing. At the time I was still in engineering school and hadn't even developed in Java yet but I had the opportunity to help organize meetups with the Paris Android User Group.

That’s how I started to meet people and saw what they were trying to build. Everyone I met at the time was really open minded and I wanted to be a part of this community and contribute to this platform by building beautiful apps too.

I started my professional journey back in 2012 and had the opportunity to work for editors and in agencies too. Today I’m working at Dashlane and I’m still organizing events with the Paris Android User Group :)

What’s one shortcut, tip, or hack you can’t live without?

I used to mostly rely on Find Usage ⌥F7 to navigate code base, but then I started using Go to Implementation ⌥⌘B. It is really *really* helpful to jump to any interface's implementation right away. It is a "more advanced" shortcut, but it is one that will make navigating a codebase with composition, contract, multi-modules, etc. really smooth. Especially when an interface and implementation can be far apart in the file hierarchies.

What's the one piece of advice you wish someone would have given you when you started on your journey?

Find what works for you to keep learning. Huyen Tue Dao gave an amazing talk with a lot of advice on this, check it out here. She covered talks, to podcasts, articles, newsletters, Twitter, community, sketchnotes, and more. She shared a lot of ways to stay up to date and gave us the honest truth: you just can't keep up with everything ^^ So find what best fits you and your lifestyle to keep improving and learning.

There will always be highs and lows in your career; knowing people who will support you is why you may be able to overcome challenges in the long run. And that is why, I would recommend you to take a look at your local developer community. Those are perfect spots to learn, share what you learn, and meet people who understand what you're doing. It’s perfect to gain knowledge, take a step back, share advice and experiences, and support each other. We're human first and foremost, and most solutions are human too.

Tell me about your journey to becoming an Android Developer and how you got started.

My path to becoming an Android developer started my senior year of high school when I Googled “What do you need to do to be a computer programmer?” We had a class assignment about researching a career. I had always been interested in coding. As a kid, I played way too many video games and wanted to learn how they worked. Then, when I got into high school, I started teaching myself to code from reading blogs.

I grew up poor in East Los Angeles and went to a school that had little money with very little access to quality technology. I didn’t know anyone else who was coding, but the Internet said to be a developer, you needed to go to college and get a bachelor’s degree. So I went and studied computer science, learning C++, JavaScript, Java, and other languages.

In 2014, I went to a panel at my community college and met AnnMaria, a co-founder of 7 Generation Games, where we develop educational games aimed at closing the math gap, especially within Latino and Indigenous communities. I applied for an internship, because I wanted to be part of making software for good. Initially, we were just making games for computers or to run on the web. But as technology evolved and we expanded to mobile, it was really important that we were developing for Android because those are the primary devices people are using in many of the communities we’re in. Because of my background, developing for Android was especially important to me because I know how valuable quality and accessible technology is for students. In 2016, I offered to take the lead on our first Android project, a game - now a series - called Making Camp. I downloaded Android Studio, cracked open the documentation and got to work.

When I graduated with my bachelor’s in 2018, I joined 7 Generation Games full-time. I am now our lead Android developer and just put our 10th app into Google Play.

What’s one shortcut, tip, or hack you can’t live without?

On Android, I primarily work in WebView. When trying to execute JavaScript code on the WebView from outside the page, it is easily facilitated by passing a string in Java with the code you want to execute. But the reverse is less common. My hack for this is if you want the app to react to JavaScript code, you have to create an event to catch the error returned from the page, then parse the string for what you wanted to do and react outside the WebView with that information.

What's the one piece of advice you wish someone would have given you when you started on your journey?

Don't be afraid to ask questions. Don't think everyone knows more than you because they don't. That said, the most useful piece of advice I was given was to read documentation. It might seem simple, but I’ve been surprised by how often people don’t. That’s advice I would give to anyone starting out.

Introducing Security By Design

Posted by Jon Markoff, Staff Developer Advocate & Sean Smith, Technical Program Manager

As a developer, are you struggling to figure out when to build security threat protection into your roadmap? Integrating security into your app development lifecycle can save a lot of time, money, and risk. That’s why we’ve launched Security by Design on Google Play Academy to help developers identify, mitigate, and proactively protect against security threats.

The Android ecosystem, including Google Play, has many built-in security features that help protect developers and users. The course Introduction to app security best practices takes these protections one step further by helping you take advantage of additional security features to build into your app. For example, Jetpack Security helps developers properly encrypt their data at rest and provides only safe and well known algorithms for encrypting Files and SharedPreferences. Are you concerned about using Rooted or compromised devices that may allow a bad actor to use your app in a non-sanctioned way? The SafetyNet Attestation API is a solution to help identify potentially dangerous patterns in usage. There are several common design vulnerabilities that are important to look out for, including using shared or improper file storage, using insecure protocols, unprotected components such as Activities, and more. The course also provides methods to test your application, to keep apps safe in the wild after launch. Finally, you can set up a Vulnerability Disclosure Program (VDP) to engage security researchers to help.

In the next course, you can learn how to integrate security at every stage of the development process by adopting the Security Development Lifecycle. The SDL is an industry standard process and in this course you’ll learn the fundamentals of setting up a program, getting executive sponsorship and integration into your development lifecycle.

Threat modeling is part of the Security Development Lifecycle, in this course you will learn to think like an attacker to identify, categorize, and address threats. By doing so early in the design phase of development, you can identify potential threats and start planning for how to mitigate them at much lower cost and create a more secure product for your users.

Improving your app’s security is a never ending process. Sign up for the Security by Design module where in a few short courses, you will learn how to integrate security into your app development lifecycle, model potential threats, and app security best practices into your app, as well as avoid potential design pitfalls.

Android @ Google I/O: 3 things to know in Modern Android Development

Posted by The Modern Android Development Team

This year’s Google I/O brought lots of updates for Modern Android Development. Here are the top 3 things you should know:

#1: Lots of new Jetpack library releases!

In recent months, several Jetpack libraries reached stable, beta or were just launched in alpha. Here are some the highlights:

To find out more about what’s new, check out the What’s new in Jetpack, What’s new in Compose and for a deep dive into Macrobenchmark: Measuring Jank and Startup with Macrobenchmark.

#2: Inspectors in Android Studio

Debugging your application becomes easier with all the inspectors provided by Android Studio Arctic Fox: for background work, like understanding what’s the status of your WorkManager workers, use Background Task Inspector; for UI use Layout Inspector, for both Android Views and Compose; for database debugging use Database Inspector.

To see the inspectors in action, check out What’s new in Android development tools.

#3: New features in Kotlin

We keep improving Kotlin on Android at all levels, from tools to APIs, and giving you different ways to learn. Kotlin Symbol Processing (KSP), now in alpha, provides a simplified compiler plugin API that can run up to 2 times faster than KAPT. Together with JetBrains, we’re addressing performance issues in the IDE and we’re seeing up to 20x faster auto-import suggestions. We added StateFlow support to DataBinding and new APIs for observing Flows in the UI without DataBinding. To learn about all the improvements we’ve made for Kotlin, check out the State of Kotlin on Android talk:
