It traces the issue to a design-system slider forked from the AOSP Material implementation and discusses debugging and code simplification. ### Source excerpt A bug report sat in the backlog for seven months. The fix took a day, deleted a third of the slider's logic, and was almost shipped with a second bug inside -- until a machine read my diff better than I did. This is the whole story: the ported behavior that never made sense, the race nobody reported, and why the best fixes remove code. The report The bug report was seven months old when it reached me. A QA engineer had filed it in December, with a screen recording and three steps: Open the people search filters. Grab the right-hand thumb of the age range slider. Drag it slowly to the left. The recording showed the problem in two seconds. The thumb does not follow the finger. It sprints ahead -- you are still crossing the gap between two ticks, and the thumb is already standing on the next one, waiting for you, like a dog that runs to the park while you are still tying your shoes. Expected: the thumb moves with the finger. Actual: it escapes. On a budget phone, on two Android versions, every time. Not a race condition, not a flake -- a perfectly deterministic lie, filmed in December, assigned to a fix-day in July. Seven months is not negligence. It is the natural half-life of a visual glitch filed as minor against a screen nobody dies on. The age filter works. You tap a tick, the value applies. Only the drag -- the one gesture the slider exists for -- feels wrong in a way that is hard to screenshot and easy to deprioritize. When the ticket finally landed on my desk, a colleague glanced at it and asked whether it had already been fixed once. It had not. But I understood his confusion later, when I opened the slider's source and found a comment that explained everything -- including why this bug felt so old. The comment that confessed The slider is not the framework's slider. Our design system ships its own Compose slider, forked from the AOSP Material one, because design needed three knobs the framework does not expose: a custom thumb radius, a custom track height, a differ ## Android Weekly Issue #744 DevFeed: [Android Weekly Issue #744]() Original publisher: [Read original article]() Published: 2026-09-13T16:28:25Z Content type: article Language: en Sources: [Android Weekly]() Topics: [Android](), [Development](), [Compose](), [Artificial Intelligence](), [Rive animation]() Tags: [android](), [android-development](), [compose](), [developers](), [lottie](), [net-11-preview-7](), [offline-speech-recognition](), [rive](), [speech](), [tutorials]() ### AI overview Android Weekly Issue #744 is a developer digest covering Android architecture and AI, annotation-based DSL APIs, animated paywalls, offline speech recognition in keyboards, Compose dialog blurring, and structural hot reload across Android, iOS, and desktop. ### Source excerpt Articles & Tutorials Sponsored Pushwoosh launches a new Push-only plan Stop overpaying for push notifications.

It uses Molecule on the JVM to observe state, kotlinx.html to render HTML fragments, Ktor to stream updates over WebSockets, and client-side JavaScript with Idiomorph to patch the DOM. It also discusses using server-sent events for unidirectional updates and the scalability tradeoffs of long-lived connections. ### Source excerpt Let's render a simple page with Ktor server and kotlinx.html: get("/users.html") { call.respondHtml { myLayout(title = "Users") { userList( users = db.users.value, ) } } } A reusable myLayout provides scaffolding, userList encapsulates the specific page content, and db.users is a StateFlow> from the persistence layer. I've been doing this over and over to create admin dashboard pages for a project. It works great right up until you leave it open for a minute or two, and its content becomes stale. Client-side frameworks exist within the ecosystem to "solve" this, such as Compose for HTML or Compose UI for Web. If your house has a leaky pipe you can also "solve" that by moving to a new house. I simply will not bring myself to abandoning HTML let alone delivery of static HTML in the response. Efforts are underway to adapt Compose for HTML for so-called isomorphic rendering. This would involve performing the initial composition on the server to produce the static HTML for the HTTP response. Then, client side as JS, mounting the same rendering code to reproduce the DOM tree and incrementally update it for future state changes. Tomorrow's Compose today Instead of waiting, I brought my own Compose on the JVM from home in the form of Molecule. Instead of managing a UI tree over time, Molecule manages a single piece of state over time. We can use that to render an HTML fragment on the server as a string, and then stream that to the client. webSocket("/users.ws") { launchMolecule(Immediate) { val users by db.users.collectAsState() createHTML().userList( users = users, ) }.collect(::send) } That's it. Ktor gives us the webSocket, Molecule runs the StateFlow which is piped into it, and kotlinx.html renders the HTML fragment of our existing content function. In the initial HTML payload you need to wire this up somehow. Something like: script { unsafe { +""" |const content = document.getElementById("content"); |const socket = new WebSocket("ws://" + location.ho ## Android Studio Rabbit 1 Canary 2 now available DevFeed: [Android Studio Rabbit 1 Canary 2 now available]() Original publisher: [Read original article]() Author: Android Studio Releaser (noreply@blogger.com) Published: 2026-08-20T13:34:55Z Content type: release Language: en Sources: [Android Studio Release Updates]() Topics: [Android Studio](), [Android Gradle Plugin](), [bug](), [Compose](), [Kotlin](), [JSON]() Tags: [android](), [android-gradle-plugin](), [android-studio](), [bug](), [compose](), [json](), [kotlin](), [preview](), [release-notes]() ### AI overview Android Studio Rabbit 1 Canary 2 is available in the Canary channel.

The release stabilizes APIs for Android XR development, while Jetpack Compose for XR is expected to reach beta soon. ### Source excerpt Posted by Amy Zeppenfeld, Developer Relations Engineer, Greg Underwood, Software Engineering Manager, Yasmine Evjen, Senior Product Manager, Android XR Since introducing the Android XR SDK, developers have transformed their ideas into innovative, immersive experiences for XR headsets and wired XR glasses. As the ecosystem expands, you can more easily take those experiences from preview to production and reach users wherever they are. Today, we're excited to announce that Jetpack SceneCore, ARCore for Jetpack XR, and XR Runtime have reached beta with Jetpack Compose for XR to follow soon! This means the APIs are stabilizing, making it a great time to start integrating them into your production workflows and creating for Android XR. Why the Jetpack XR SDK? The Jetpack XR SDK includes all the tools and libraries you need to build immersive and augmented experiences for Android XR. Whether you're porting an existing 2D app or creating a new 3D XR app from scratch, you can do so using the familiar Android development tools you already know and love. To support your development, this release focuses on providing the fundamental building blocks across the SDK: Jetpack SceneCore: Build and manipulate the Android XR scene graph with 3D content. You can arrange 3D models, play spatial audio, and use the robust entity-component system to create, control, and manage entities. ARCore for Jetpack XR: Bring digital content into the real world with perception capabilities. This library powers depth estimation, persistent anchors, hit testing, and plane identification. XR Runtime: Provides the essential runtime foundation of the SDK, handling device lifecycles, session creation, and system configurations that enable the API surface. Jetpack Compose for XR: Create spatial UI layouts that take advantage of Android XR's spatial capabilities. This library lets you use familiar Compose concepts to create spatial UIs and will be reaching Beta soon. What's new in Beta?

It distinguishes object retrieval from creation, discusses process, navigation-destination, request, and feature-session lifetimes, and recommends testing both retention and exit behavior. ### Source excerpt Compose makes it easy to request an object close to the UI that uses it. Proximity is useful, but it does not define ownership. Recomposition can call a function many times. Navigation can keep or discard a back-stack entry. The operating system can recreate the process. A sound scope names the event that owns the object. Separate retrieval from creation Ask two questions for each injected object: Where is the object retrieved? Which lifecycle creates and releases it? A repository retrieved by a composable can still be process-scoped. A screen model can be owned by a navigation destination. A transient formatter can be created for each request. Write the lifetime next to the definition and test that the object survives, or does not survive, the intended event. ## Exploring Compose HTML for Server Side Rendering DevFeed: [Exploring Compose HTML for Server Side Rendering]() Original publisher: [Read original article]() Author: Frederik Pietzko Published: 2026-08-14T12:15:09Z Content type: article Language: en Sources: [Kotlin : A concise multiplatform language developed by JetBrains | The JetBrains Blog]() Topics: [Compose](), [Server-side rendering](), [Web Development](), [Kotlin](), [multiplatform](), [HTML](), [React](), [Next.js](), [Nuxt.js](), [Svelte]() Tags: [backend](), [compose](), [compose-multiplatform](), [development](), [framework](), [html](), [kotlin](), [multiplatform](), [news](), [react](), [server](), [svelte](), [ui](), [vue](), [web](), [web-development]() ### AI overview An exploratory proposal for extending Compose HTML with a JVM target to support server-side rendering. It argues that Kotlin and Compose components could provide type-safe, reusable server-rendered UI without a separate templating language, while discussing the trade-offs of canvas-based web rendering for SEO, loading times, and accessibility. ### Source excerpt Something is happening in server-rendered web development. React shipped Server Components. HTMX made "hypermedia" cool again. Phoenix LiveView proved a server can push interactive UI updates without a client framework in sight. Every ecosystem seems to be rediscovering the server as a place to render UI, except one: the JVM.

It covers primary and dismiss actions, gesture indicators, API integration, and the new Modifier.oneHandedGesture. ### Source excerpt Posted by Chiara Chiappini, Developer Relation Engineer, Android Developer Relations One-handed gestures offer a convenient and touch-free way for users to interact with their watches, enabling them to perform key actions using only the hand on which the device is worn. First introduced on Pixel Watch with Wear OS 6.1, one-handed gestures made quick interactions effortless, such as starting and stopping a timer, accepting calls, and controlling media. Now, with Wear OS 7, we're expanding this functionality with a new Gestures framework that allows OEMs to map gestures to primary actions and dismissals, and an API to bring gesture control to the developer community. Starting with the 1.7 beta release of Compose for Wear OS, you can seamlessly integrate gesture control into your Wear Compose apps. To use this release, upgrade your Wear Compose dependency to: androidx.wear.compose:compose-material3:1.7.0-beta01 Designing for one-handed interaction The one-handed gestures framework is designed around two primary interaction patterns that allow users to take action without touching the screen: Primary action, which on Pixel Watch is mapped to a double-pinch gesture: this action should be mapped to the most important task in a given context. For example, users can perform this gesture to take a photo in a camera app, start/stop a timer, or accept an incoming call. Dismiss action, which on Pixel Watch is mapped to a wrist turn gesture: this action is mapped to system back by default and provides an intuitive way to close interruptive screens or get back to the watch face. It may be overridden for specific use cases, such as silencing an incoming phone call. These gestures are currently available on Pixel Watch 3 and newer, and the Wear OS gesture framework is available to all Wear OS device manufactures to adopt.
