    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

    https://www.youtube.com/watch?v=IaNpcrCSDiI

    Get ready to take your app’s performance to the next level! Google I/O 2025, brought an inside look at cutting-edge tools and techniques to boost user satisfaction, enhance technical performance metrics, and drive those all-important key performance indicators. Imagine an end-to-end workflow that streamlines performance optimization.

    Redesigned UiAutomator API

      • To make benchmarking reliable and reproducible, there’s the brand new UiAutomator API. Write robust test code and run it on your local devices or in Firebase Test Lab, ensuring consistent results every time.

    Macrobenchmarks

      • Once your tests are in place, it’s time to measure and understand. Macrobenchmarks give you the hard data, while App Startup Insights provide actionable recommendations for improvement. Plus, you can get a quick snapshot of your app’s health with the App Performance Score via DAC. These tools combined give you a comprehensive view of your app’s performance and where to focus your efforts.

    R8, More than code shrinking and obfuscation

      • You might know R8 as a code shrinking tool, but it’s capable of so much more! The talk dives into R8’s capabilities using the “Androidify” sample app. You’ll see how to apply R8, troubleshoot any issues (like crashes!), and configure it for optimal performance. It’ll also be shown how library developers can include “consumer Keep rules” so that their important code is not touched when used in an application.

    #3: Build Richer Image and Video Experiences

  • Building excellent games with better graphics and performance



    Posted by Matthew McCullough – VP of Product Management, Android

    We’re stepping up our multiplatform gaming offering with exciting news dropping at this year’s Game Developers Conference (GDC). We’re bringing users more games, more ways to play your games across devices, and improved gameplay. You can read all about the updates for users from The Keyword. At GDC, we’ll be diving into all of the latest games coming to Play, plus new developer tools that’ll help improve gameplay across the Android ecosystem.

    Today, we’re sharing a closer look at what’s new from Android. We’re making Vulkan the official graphics API on Android, enabling you to build immersive visuals, and we’re enhancing the Android Dynamic Performance Framework (ADPF) to help you deliver longer, more stable gameplays. Check out the video or keep reading below.

    More immersive visuals built on Vulkan, now the official graphics API

    These days, games require more processing power for realistic graphics and cutting-edge visuals. Vulkan is an API used for low level graphics that helps developers maximize the performance of modern GPUs, and today we’re making it the official graphics API for Android. This unlocks advanced features like ray tracing and multithreading for realistic and immersive gaming visuals. For example, Diablo Immortal used Vulkan to implement ray tracing, bringing the world of Sanctuary to life with spectacular special effects, from fiery explosions to icy blasts.

    We’re excited to announce that Android is transitioning to a modern, unified rendering stack with Vulkan at its core. Starting with our next Android release, more devices will use Vulkan to process all graphics commands. If your game is running on OpenGL, it will use ANGLE as a system driver that translates OpenGL to Vulkan. We recommend testing your game on ANGLE today to ensure it’s ready for the Vulkan transition.

    We’re also partnering with major game engines to make Vulkan integration easier. With Unity 6, you can configure Vulkan per device while older versions can access this setting through plugins. Over 45% of sessions from new games on Unity* use Vulkan, and we expect this number to grow rapidly.

    To simplify workflows further, we’re teaming up with the Samsung Austin Research Center to create an integrated GPU profiler toolchain for Vulkan and AI/ML optimization. Coming later this year, this tool will enable developers to make graphics, memory and compute workloads more efficient.

    Longer and smoother gameplay sessions with ADPF

    Android Dynamic Performance Framework (ADPF) enables developers to adjust between the device and game’s performance in real-time based on the thermal state of the device, and it’s getting a big update today to provide longer and smoother gameplay sessions. ADPF is designed to work across a wide range of devices including models like the Pixel 9 family and the Samsung S25 Series. We’re excited to see MMORPGs like Lineage W integrating ADPF to optimize performance on their core target devices.
