Google is turning Android into a 'sloperating' system. Your thoughts? Google released Android 17, transforming the platform from an operating system into an 'intelligence system' with deep AI integration. The update introduces mandatory large-screen resizability, AppFunctions for AI agent orchestration, and tools for developers to build adaptive apps. This shift aims to anticipate user needs and expand engagement opportunities across devices. 16 June 2026 Today we're releasing Android 17 and making it available on most supported Pixel devices. Look for new devices running Android 17 in the coming months. Android 17 marks the start of our transition to an intelligence system, putting your apps at the center. It's shifting to an adaptive-first development standard by introducing mandatory large-screen resizability, all while delivering next-generation privacy, security, media, camera, and performance. We'll cover all that in this post, as well as how we're bringing together next generation tools, libraries, and agent skills to help your apps embrace the opportunity. Throughout the past year, from our Canary channel to our Beta releases, we’ve collaborated with you in the developer community to build a platform you and your users can trust. To that end, this moment marks the availability of the source code at the Android Open Source Project https://source.android.com/ AOSP . This allows you to examine the source code https://cs.android.com/ for a deeper understanding of how Android works. Let's dive deeper into Android 17. With deep integration between hardware, software and AI, we’re transforming Android from an operating system to an intelligence system. It's about delivering new helpful experiences that anticipate user needs, and it brings more opportunities for engagement with your apps. To that end, Android 17 expands the capabilities of AppFunctions, a platform API with a corresponding Jetpack library. It allows you to contribute your app's unique capabilities as orchestratable "tools" for Android MCP, the on-device equivalent of the Model Context Protocol https://modelcontextprotocol.io/ . AI agents and assistants like Google Gemini can discover and execute AppFunctions to perform workflows on behalf of the user with direct access to the app's local state. The Jetpack library, currently in alpha, makes adding AppFunctions as easy as annotating a class and adding KDoc comments. / A note app's AppFunction s. / class NoteFunctions private val noteRepository: NoteRepository { / Adds a new note to the app. @param appFunctionContext The execution context. @param title The title of the note. @param content The note's content. / @AppFunction isDescribedByKDoc = true suspend fun createNote appFunctionContext: AppFunctionContext, title: String, content: String : Note { return noteRepository.createNote title, content } } We’ve also launched an AppFunctions agent skill http://github.com/android/skills/tree/main/on-device/appfunctions that analyzes your app’s key workflows, automatically generates the required Kotlin code, optimizes your KDocs for LLM tool-calling, and provides ADB commands for testing and debugging. The Gemini integration is currently in a private preview with trusted testers, but you can begin preparing your apps now. In addition to ADB commands to execute your AppFunctions, we've provided a test agent app http://github.com/android/appfunctions/releases/initial that includes an interface to discover and execute your app functions and simulate an AI agent integration. Join our integration early access program at goo.gle/eap-af http://goo.gle/eap-af for a chance to be among the first apps to deploy AppFunctions to production. Your users no longer rely on a single form factor; they transition between phones, foldables, tablets, laptops, automotive displays, and immersive XR environments. Now, with over 580 million large screen devices https://developer.android.com/blog/posts/adaptive-development-for-the-expanding-android-ecosystem in the hands of users and the forthcoming launch of Googlebooks https://blog.google/products-and-platforms/platforms/android/meet-googlebook/ , the next generation of ChromeOS built on the Android stack, adaptive is no longer just a technical goal. It’s a massive opportunity to reach highly engaged users, which is one of the reasons we're shifting to an adaptive-first development standard https://developer.android.com/adaptive-apps . To ensure apps deliver a premium experience across all form factors, including mobile devices running in desktop mode on connected displays, Android 17 API level 37 removes the developer opt-out for orientation and resizability restrictions on large screen devices https://developer.android.com/guide/topics/large-screens sw 600 dp for apps targeting API level 37. The system will ignore legacy manifest attributes and runtime APIs, including screenOrientation, setRequestedOrientation , resizeableActivity=false, and aspect ratio constraints minAspectRatio/maxAspectRatio . Games based on app category https://support.google.com/googleplay/android-developer/answer/9859673?hl=en in Google Play remain exempt. Your app must be ready to adapt to any window size, respect the user's preferred device posture, and support free-form windowing natively. Android 17 introduces powerful new windowing capabilities that redefine how users multitask, demanding even greater layout flexibility from your apps: App Bubbles and Bubble Bar in action To prevent disruptive state loss and stutter, Android 17 updates the default behavior for Activity recreation. The system will no longer restart activities by default for typical configuration changes that do not require a full UI redraw including CONFIG KEYBOARD https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo config keyboard , CONFIG KEYBOARD HIDDEN https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo config keyboard hidden , CONFIG NAVIGATION https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo config navigation , CONFIG TOUCHSCREEN https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo config touchscreen , and CONFIG COLOR MODE https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo config color mode . Instead, running activities will receive these updates via onConfigurationChanged , enabling smooth transitions. If your application explicitly relies on a full restart to reload resources for these changes, you must now explicitly opt-in using the new android:recreateOnConfigChanges https://developer.android.com/reference/kotlin/android/R.attr recreateonconfigchanges manifest attribute. Android 17 adds Continue On to help users seamlessly transition a task between Android devices. The user sees a suggestion for the most recently opened app from their mobile device in their tablet taskbar, providing a one-tap affordance to launch the app and deep-link where they left off. Continue on can support app-to-web transitions, including falling back to using the web if the app isn't installed. class MyHandoffActivity : Activity { ... override fun onCreate savedInstanceState: Bundle? { super.onCreate savedInstanceState // Do stuff ... // Enable handoff setHandoffEnabled true, null } // Override and implement onHandoffActivityDataRequested override fun onHandoffActivityDataRequested handoffRequestInfo: HandoffActivityDataRequestInfo : HandoffActivityData { // Create and return handoff data } } To help you adapt your apps to meet the new Android 17 requirements, we've launched the Jetpack Compose adaptive skill https://github.com/android/skills/tree/main/jetpack-compose/adaptive . This AI-powered developer workflow helps you implement the best adaptive practices: Compose offers the easiest way to build adaptive apps, and that's just one of the many reasons https://developer.android.com/develop/ui/compose/first why-compose-first we believe that all Android UI should be built with Compose. To that end, Android development is now Compose-first https://developer.android.com/develop/ui/compose/first . All new Android APIs, libraries, tools, and developer guidance will be built exclusively for Jetpack Compose. Legacy View components in the android.widget package and View-based Jetpack libraries like Fragments, RecyclerView, and ViewPager are now in maintenance mode. They will receive only critical bug fixes, and no new features. TIP Ready to migrate? Use our AI-driven XML to Compose Migration Skill to automatically analyze your legacy View layouts and convert them into highly-adaptive Compose code. App performance means a smooth user interface, fast app start times, and efficient multitasking; Android 17 has impactful improvements in all of these areas. Memory usage is one of the silent foundations of overall performance. When a foreground app or service grows unchecked, memory management spikes CPU and battery utilization and eventually leads to the termination of other well-behaved cached apps and background jobs, ultimately forcing slower cold starts and impaired multitasking. Starting in Android 17, the system will enforce strict app memory limits based on a device's total RAM, abruptly terminating offending processes. New things to help you navigate these tighter requirements: val profilingManager = applicationContext .getSystemService ProfilingManager::class.java val triggers = ArrayList
