Android 15 is released to AOSP

Posted by Matthew McCullough – VP of Product Management, Android Developer

Today we're releasing Android 15 and making the source code available at the Android Open Source Project (AOSP). Android 15 will be available on supported Pixel devices in the coming weeks, as well as on select devices from Samsung, Honor, iQOO, Lenovo, Motorola, Nothing, OnePlus, Oppo, realme, Sharp, Sony, Tecno, vivo, and Xiaomi in the coming months.

We're proud to continue our work in open source through the AOSP. Open source allows anyone to build upon and contribute to Android, resulting in devices that are more diverse and innovative. You can leverage your app development skills in Android Studio with Jetpack Compose to create applications that thrive across the entire ecosystem. You can even examine the source code for a deeper understanding of how Android works.

Android 15 continues our mission of building a private and secure platform that helps improve your productivity while giving you new capabilities to produce beautiful apps, superior media and camera experiences, and an intuitive user experience, particularly on tablets and foldables.

Starting today, we're kicking off a new educational series called Spotlight Weeks, where we dive into technical topics across Android, beginning with a week of content on Android 15. Check out what we'll be covering throughout the week, as well as today's deep dive into edge-to-edge.

Improving your developer experience

While most of our work to improve your productivity centers around tools like Android Studio, Jetpack Compose, and the Android Jetpack libraries, each new Android platform release includes quality-of-life updates to improve the development experience. For example, Android 15 gives you new insights and telemetry to allow you to further tune your app experience, so you can make changes that improve the way your app runs on any platform release.

Improving typography and internationalization

Android helps you make beautiful apps that work well across the global diversity of the Android ecosystem.

    • You can now create a FontFamily instance from variable fonts in Android 15 without having to specify wght and ital axes using the buildVariableFamily API; the text renderer will automatically adjust the values of the wght and ital axes to match the displaying text with compatible fonts.
    • The font file in Android 15 for Chinese, Japanese, and Korean (CJK) languages, NotoSansCJK, is now a variable font, opening up new possibilities for creative typography.

Camera and media improvements

Each Android release helps you bring superior media and camera experiences to your users.

    • For screens that contain both HDR and SDR content, Android 15 allows you to control the HDR headroom with setDesiredHdrHeadroom to prevent SDR content from appearing too washed-out.
    • Android 15 supports intelligently adjusting audio loudness and dynamic range compression levels for apps with AAC audio content that contains loudness metadata so that audio levels can adapt to user devices and surroundings. To enable, instantiate a LoudnessCodecController with the audio session ID from the associated AudioTrack.
    • Low Light Boost in Android 15 adjusts the exposure of the Preview stream in low-light conditions, enabling enhanced image previews, scanning QR codes in low light, and more.
    • Advanced flash strength adjustments in Android 15 enable precise control of flash intensity in both SINGLE and TORCH modes while capturing images.
    • Android 15 extends Universal MIDI Packets support to virtual MIDI apps, enabling composition apps to control synthesizer apps as a virtual MIDI 2.0 device just like they would with an USB MIDI 2.0 device.

Improving the user experience

We continue to refine the Android user experience with every release, while working to improve performance and battery life. Here is just some of what Android 15 brings to make the experience more intuitive, performant, and accessible.

Privacy and security enhancements

Privacy and security are at the core of everything we do, and we work to make meaningful improvements to protect your apps and our users with each platform release.

Get your apps, libraries, tools, and game engines ready!

If you develop an SDK, library, tool, or game engine, it's particularly important to prepare any necessary updates immediately to prevent your downstream app and game developers from being blocked by compatibility issues and allow them to target the latest SDK features. Please let your developers know if updates are needed to fully support Android 15.

Testing your app involves installing your production app using Google Play or other means onto a device or emulator running Android 15. Work through all your app's flows and look for functional or UI issues. Review the behavior changes to focus your testing. Here are several changes to consider that apply even if you don't yet target Android 15:

    • Package stopped state changes - Android 15 updates the behavior of the package FLAG_STOPPED state to keep apps stopped until the user launches or indirectly interacts with the app.
    • Support for 16KB page sizes - Beginning with Android 15, 16 KB page size support will be available on select devices as a developer option. Additionally, Android Studio also offers an emulator system image with 16 KB support through the SDK manager. If your app or library uses the NDK, either directly or indirectly through a library, you can use the developer option in the QPR beta or the Android 15 emulator system image to test and fix applications to prepare for Android devices with 16 KB page sizes in the near future.
    • Removed legacy emoji font file - Some Android 15 devices such as Pixel will no longer have the bitmap NotoColorEmojiLegacy.ttf file included for compatibility since Android 13 and will only have the default vector file.

Please thoroughly exercise libraries and SDKs that your app is using during your compatibility testing. You may need to update to current SDK versions or reach out to the developer for help if you encounter any issues.

Once you’ve published the Android 15-compatible version of your app, you can start the process to update your app's targetSdkVersion.

App compatibility

We’re working to make updates faster and smoother with each platform release by prioritizing app compatibility. In Android 15 we’ve made most app-facing changes opt-in until your app targets SDK version 35. This gives you more time to make any necessary app changes.

To make it easier for you to test the opt-in changes that can affect your app, based on your feedback we’ve made many of them toggleable again this year. With the toggles, you can force-enable or disable the changes individually from Developer options or adb. Check out how to do this, here.

Get started with Android 15

If you have a supported Pixel device, you will receive the public Android 15 over the air update when it becomes available. If you don't want to wait, you can get the most recent quarterly platform release (QPR) beta by joining the Android 15 QPR beta program at any time.

If you're already in the QPR beta program on a Pixel device that supports the next Android release, you'll likely have been offered the opportunity to install the first Android 15 QPR beta update. If you want to opt-out of the beta program without wiping your device, don't install the beta and instead wait for an update to the release version when it is made available on your Pixel device. Once you've applied the stable release update, you can opt out without a data wipe as long as you don't apply the next beta update.

Stay tuned for the next five days of our Spotlight Week on Android 15, where we'll be covering topics like edge-to-edge, passkeys, updates to foreground services, picture-in-picture, and more. Follow along on our blog, X, LinkedIn or YouTube channels. Thank you again to everyone who participated in our Android developer preview and beta program. We're looking forward to seeing how your apps take advantage of the updates in Android 15.

Impact of upcoming reporting changes on Bid Manager API

On October 1, 2024, the Anonymous Inventory Modeling (AIM) reporting dimension will sunset and DST/ROC (Regulatory Operating Costs) and Total Media Cost metrics will become incompatible with YouTube reports in Display & Video 360. This will impact the structure of the reports that can be created and run using the Bid Manager API.

The relevant AIM dimension is defined by Filter value FILTER_ANONYMOUS_INVENTORY_MODELING. Once sunset, queries.create and queries.run requests creating and running Query resources with this dimension will return a 400 error.

The relevant cost metrics are defined by any Metric value using the prefix METRIC_TOTAL_MEDIA_COST_ or METRIC_FEE32_. Starting October 1, queries.create and queries.run requests creating and running Query resources of ReportType YOUTUBE that use these metrics will return a 400 error. In the weeks following October 1, we will update existing YouTube queries that use these values to remove the metrics. In place of total cost metrics, we recommend the use of individual media cost metrics instead, which can be added together with other supported fees to calculate the now unavailable total media cost.

To avoid any interruption of service, review your reports to remove the AIM dimension from any existing reports and all relevant cost metrics from any existing YouTube reports.

Read more about these changes on our release notes.

If you run into issues or have questions about these changes, please contact us using our new Bid Manager API Technical support contact form.

#WeArePlay | Estante Mágica, the app helping kids publish their own books

Posted by Robbie McLachlan, Developer Marketing

In our latest film for #WeArePlay, which celebrates the people behind apps and games, we meet Robson from Rio de Janeiro, Brazil. As the co-founder of Estante Mágica, he created an app that turns kids into published authors, sparking their imagination and love for reading. Robson's journey from the favelas to creating a platform that inspires millions of young minds is helping to revolutionize education in Brazil. Discover how Estante Mágica is making a lasting impact on education, one story at a time.



What was the inspiration behind Estante Mágica?

It’s a combination of my personal journey and a deep belief in the transformative power of education. Growing up in the Rocinha favela, I saw first-hand how education could change lives — my illiterate grandparents always believed that education was the key to real change, and passed that belief down to me. I wanted to create a tool that nurtures literacy so I teamed up with my friend Pedro to create Estante Mágica.

Estante Mágica, which translates to "Magic Bookshelf," is our way of giving every child the chance to become an author, create something magical that they can be proud of, and to see their own imagination come to life. We designed the app to be a bridge, reaching not just urban schools but also rural and underserved communities, including indigenous villages and areas with fewer resources.

Can you tell us about a moment that showed you the power of Estante Mágica?

Recently, I visited a school in a small village in Rio de Janeiro. The principal apologized for being late to our meeting, explaining that she had just met with a father and mother who wanted to enroll in adult education classes. When she asked them why they wanted to learn to read and write in their 30s and 40s, they told her, "Our son wrote a book here last year, and we don't know how to read it. It's our dream to be able to read the book our son wrote." That moment hit me hard. It was proof that our app isn’t just about helping kids become authors; it's about inspiring entire families to embrace literacy and education.

Tell us about the Autograph Days

These events are held at schools and are all about celebrating the young authors who have created their own books. Each child receives a printed copy of their book, and the day is set up just like a traditional book signing event. The event is not only about the children’s hard work but also a moment of pride for parents and teachers, who see the joy and confidence this experience brings to the kids.

What’s next for Estante Mágica?

One major focus is integrating more AI into the app. We want to make it so that when kids create their characters or stories, they can interact with them more dynamically. Imagine a character in a game being able to respond to a child’s questions or comments – that’s the kind of interaction we’re aiming for. We’re keeping an eye on some new features like text-to-video and image-to-video which could add a whole new layer to how kids can bring their stories to life. Ultimately, we’re planning to bring the magic of storytelling to children around the world and expand our platform to more schools, especially in underserved areas.
