    In today’s diverse device ecosystem, users expect their favorite applications to function seamlessly across various form factors, including phones, tablets, Chromebooks, automobiles, and emerging XR glasses and headsets. Our recommended approach for developing applications that excel on each of these surfaces is to create a single, adaptive application. This strategy avoids the need to rebuild the application for every screen size, shape, or input method, ensuring a consistent and high-quality user experience across all devices.

    The talk emphasizes that you don’t need to rebuild apps for each form factor. Instead, small, iterative changes can unlock an app’s potential.

    Here are some resources we encourage you to use in your apps:

    New feature support in Jetpack Compose Adaptive Libraries

      • We’re continuing to make it as easy as possible to build adaptively with Jetpack Compose Adaptive Libraries. with new features in 1.1 like pane expansion and predictive back. By utilizing canonical layout patterns such as List Detail or Supporting Pane layouts and integrating your app code, your application will automatically adjust and reflow when resized.

    Navigation 3

      • The alpha release of the Navigation 3 library now supports displaying multiple panes. This eliminates the need to alter your navigation destination setup for separate list and detail views. Instead, you can adjust the setup to concurrently render multiple destinations when sufficient screen space is available.

    Updates to Window Manager Library

      • AndroidX.window 1.5 introduces two new window size classes for expanded widths, facilitating better layout adaptation for large tablets and desktops. A width of 1600dp or more is now categorized as “extra large,” while widths between 1200dp and 1600dp are classified as “large.” These subdivisions offer more granularity for developers to optimize their applications for a wider range of window sizes.

    Support all orientations and be resizable

    Extend to Android XR

    Upgrade your Wear OS apps to Material 3 Design

    You should build a single, adaptive mobile app that brings the best experiences to all Android surfaces. By building adaptive apps, you meet users where they are today and in the future, enhancing user engagement and app discoverability. This approach represents a strategic business decision that optimizes an app’s long-term success.

    #2: Enhance your app’s performance optimization

  • Build adaptive Android apps that shine across form factors



    Posted by Fahd Imtiaz – Product Manager, Android Developer

    https://www.youtube.com/watch?v=15oPNK1W0Tw

    If your app isn’t built to adapt, you’re missing out on the opportunity to reach a giant swath of users across 500 million devices! At Google I/O this year, we are exploring how adaptive development isn’t just a good idea, but essential to building apps that shine across the expanding Android device ecosystem. This is your guide to meeting users wherever they are, with experiences that are perfectly tailored to their needs.

    The advantage of building adaptive

    In today’s multi-device world, users expect their favorite applications to work flawlessly and intuitively, whether they’re on a smartphone, tablet, or Chromebook. This expectation for seamless experiences isn’t just about convenience; it’s an important factor for user engagement and retention.

    For example, entertainment apps (including Prime Video, Netflix, and Hulu) users on both phone and tablet spend almost 200% more time in-app (nearly 3x engagement) than phone-only users in the US*.

    Peacock, NBCUniversal’s streaming service has seen a trend of users moving between mobile and large screens and building adaptively enables a single build to work across the different form factors.

    “This allows Peacock to have more time to innovate faster and deliver more value to its customers.”

    – Diego Valente, Head of Mobile, Peacock and Global Streaming

    Adaptive Android development offers the strategic solution, enabling apps to perform effectively across an expanding array of devices and contexts through intelligent design choices that emphasize code reuse and scalability. With Android’s continuous growth into new form factors and upcoming enhancements such as desktop windowing and connected displays in Android 16, an app’s ability to seamlessly adapt to different screen sizes is becoming increasingly crucial for retaining users and staying competitive.

    Beyond direct user benefits, designing adaptively also translates to increased visibility. The Google Play Store actively helps promote developers whose apps excel on different form factors. If your application delivers a great experience on tablets or is excellent on ChromeOS, users on those devices will have an easier time discovering your app. This creates a win-win situation: better quality apps for users and a broader audience for you.

    Latest in adaptive Android development from Google I/O

    To help you more effectively build compelling adaptive experiences, we shared several key updates at I/O this year.

    Build for the expanding Android device ecosystem

    Your mobile apps can now reach users beyond phones on over 500 million active devices, including foldables, tablets, Chromebooks, and even compatible cars, with minimal changes. Android 16 introduces significant advancements in desktop windowing for a true desktop-like experience on large screens and when devices are connected to external displays. And, Android XR is opening a new dimension, allowing your existing mobile apps to be available in immersive virtual environments.

    The mindset shift to Adaptive

    With the expanding Android device ecosystem, adaptive app development is a fundamental strategy. It’s about how the same mobile app runs well across phones, foldables, tablets, Chromebooks, connected displays, XR, and cars, laying a strong foundation for future devices and differentiating for specific form factors. You don’t need to rebuild your app for each form factor; but rather make small, iterative changes, as needed, when needed. Embracing this adaptive mindset today isn’t just about keeping pace; it’s about leading the charge in delivering exceptional user experiences across the entire Android ecosystem.

    examples of form factors including vr headset

    Leverage powerful tools and libraries to build adaptive apps:

      • Compose Adaptive Layouts library: This library makes adaptive development easier by allowing your app code to fit into canonical layout patterns like list-detail and supporting pane, that automatically reflow as your app is resized, flipped or folded. In the 1.1 release, we introduced pane expansion, allowing users to resize panes. The Socialite demo app showcased how one codebase using this library can adapt across six form factors. New adaptation strategies like “Levitate” (elevating a pane, e.g., into a dialog or bottom sheet) and “Reflow” (reorganizing panes on the same level) were also announced in 1.2 (alpha). For XR, component overrides can automatically spatialize UI elements.

      • Jetpack Navigation 3 (Alpha): This new navigation library simplifies defining user journeys across screens with less boilerplate code, especially for multi-pane layouts in Compose. It helps handle scenarios where list and detail panes might be separate destinations on smaller screens but shown together on larger ones. Check out the new Jetpack Navigation library in alpha.

      • Jetpack Compose input enhancements: Compose’s layered architecture, strong input support, and single location for layout logic simplify creating adaptive UIs. Upcoming in Compose 1.9 are right-click context menus and enhanced trackpad/mouse functionality.

      • Window Size Classes: Use window size classes for top-level layout decisions. AndroidX.window 1.5 introduces two new width size classes – “large” (1200dp to 1600dp) and “extra-large” (1600dp and larger) – providing more granular breakpoints for large screens. This helps in deciding when to expand navigation rails or show three panes of content. Support for these new breakpoints was also announced in the Compose adaptive layouts library 1.2 alpha, along with design guidance.

      • Compose previews: Get quick feedback by visualizing your layouts across a wide variety of screen sizes and aspect ratios. You can also specify different devices by name to preview your UI on their respective sizes and with their inset values.

      • Testing adaptive layouts: Validating your adaptive layouts is crucial and Android Studio offers various tools for testing – including previews for different sizes and aspect ratios, a resizable emulator to test across different screen sizes with a single AVD, screenshot tests, and instrumental behavior tests. And with Journeys with Gemini in Android Studio, you can define tests using natural language for even more robust testing across different window sizes.

    Ensuring app availability across devices

    Avoid unnecessarily declaring required features (like specific cameras or GPS) in your manifest, as this can prevent your app from appearing in the Play Store on devices that lack those specific hardware components but could otherwise run your app perfectly.

    Handling different input methods

    Remember to handle various input methods like touch, keyboard, and mouse, especially with Chromebook detachables and connected displays.

    Prepare for orientation and resizability API changes in Android 16

    Beginning in Android 16, for apps targeting SDK 36, manifest and runtime restrictions on orientation, resizability, and aspect ratio will be ignored on displays that are at least 600dp in both dimensions. To meet user expectations, your apps will need layouts that work for both portrait and landscape windows, and support resizing at runtime. There’s a temporary opt-out manifest flag at both the application and activity level to delay these changes until targetSdk 37, and these changes currently do not apply to apps categorized as “Games”. Learn more about these API changes.

    Adaptive considerations for games

    Games need to be adaptive too and Unity 6 will add enhanced support for configuration handling, including APIs for screenshots, aspect ratio, and density. Success stories like Asphalt Legends Unite show significant user retention increases on foldables after implementing adaptive features.
