Contributed R8 support to shadow, main benefit is you could produce pretty optimized uber jars now (on top of just tree-shaking). Should be pretty handy for CLIs. github.com/GradleUp/shadow/re...

Metro 1.3.0 has rich diagnostics and experimental runtime tracing! github.com/ZacSweers/metro/re...

Need a license information screen for your Kotlin Multiplatform app? AboutLibraries collects dependency and license information at compile time, then provides simple APIs and Compose components to display it – with no runtime overhead. Explore it on Klibs.io 👇 https://kotl.in/bhj2xq

One of the usual problems when dealing with bugs is not recording screen at the right moment. Emu records everything you do including semantically, so capturing bugs is just one button away. Examine screen or actions later, send it to colleagues. And LLM can capture these too. And reproduce issues

I'm honestly shocked they took on this burden for so long. What I'd like to see is companies that rely on Maven and OSS projects to pay for this kind of infrastructure. It would make more sense than taking a cut from GitHub sponsors.

Super sympathetic to Sonatype's situation, hosting isn't free. But announcing this with paltry limits and no public pricing options (a sales contact ain't it) is bad for everyone and going to be a major disruption to the JVM and Kotlin ecosystems. central.sonatype.org/publish/mave...

I've been working on a Kotlin/Compose Multiplatform to interpolate sRGB colors as mixtures of paints/pigments. It can produce results that are more appealing than the traditional sRGB interpolation that Composes uses (see screenshot). Not quite ready for release yet. github.com/romainguy/vi...

I just published a new open-source project, Compose Navigation Graph! ⛵️ Compose Navigation Graph plugin for Android Studio that visualizes your entire app flow as an interactive map of rendered previews, typed arguments, and transitions. github.com/skydoves/com...

Official mesh gradient support #JetpackCompose is coming soon👀 available in Compose 1.12 alphas at the moment! what other graphical effects do you want?

Introducing Touch Robot, something that has materially changed how I write screenshot tests. We've been using it at Block for ~2 years to catch animation and gesture bugs that static screenshots miss. saket.me/touch-robot/

github.com/yschimke/com... Awesome work @schimke.ee . Started a similar project, but will probably archive it in favor of yours. Do you plan to export semantic information as json, so the content can be analyzed via tools without the visual image? (also that information could be used to visualize)

One underrated improvement Metro brings is its easy setup. No more configuring KAPT, runtime modules, keeping versions in sync, etc. You apply the Gradle plugin, setup a tiny graph and the rest is driven through constructor injection, @ContributesBinding and its other features. This was all I needed

💠 Haze 2.0-alpha01 is out! This is a big release, splitting Haze up into layers, with the goal of enabling pluggable visual effects. Let me know what you think! chrisbanes.me/posts/haze-2...

Say hello to Compose Hot Reload 1.1 🔥 Please give it a try and provide feedback: github.com/JetBrains/co... ☕️ JBR 25 support ⚡️ Recompilation Speed optimizations 😎 New visuals, New DevTools UX 📦 Faster, more lightweight protocol under the hood

Metro reaches 1.0! It's the proudest work of my career and I strongly feel this is how dependency injection in Kotlin should be. Thank you to everyone that's contributed and helped this project get to where it's at. Metro wouldn't be where it is without you. www.zacsweers.dev/metro-is-sta...

#JetpackCompose version 1.11 has landed! So many new APIs to try out along with some important changes. We've also detailed 4 (!) new large Experimental APls that we are actively looking for feedback on: 💅🏻 Styles! 🚥 Grid 💪🏻 FlexBox 🎞️ MediaQuery android-developers.googleblog.com/2026/04/jetp...

Metro 0.13.0 adds top-level contribution providers, Circuit code gen, and a new @DefaultBinding annotation. This also removes most deprecated APIs as Metro prepares to go stable (!!). If you have runtime API feedback, now is the time! github.com/ZacSweers/me...

Snapshot of Compose "Snapshot" 🦢 Working on another snapshot feature for HotSwan, which captures a device screenshot after every successful hot reload and pairs it with code diff that triggered the reload. You can do Code Time Traveling (revert) to a specific snapshot moment.

Trying to navigate how serialization works with Nav3 routes in multiplatform? Check out these great new docs we just published: kotlinlang.org/docs/...

The answer was no, so I'm building this myself as v2 of github.com/saket/swipe. Here's a first draft:

Custom View Preview deprecation. The Android Studio team is deprecating the Custom View Preview feature in the coming releases. If you're still using Views, it's really time to shift to Jetpack Compose. developer.android.com/studio/relea...

My fav new feature in the latest Android release is "Connected Displays".🖥️ You are able to plug in your phone to a big screen, and benefit from all the extra space that the screen provides 🤯 This means you should *really* ensure your app works on diff screen sizes.

Given this, calls for boycotting Square OSS are stupid. It's disrespectful to the hard work all these ex-Square engs have done. It won't hurt Square the company in any meaningful way, it just makes a bunch of your Android peers sad.

What happens to Square / Block Android OSS projects post layoffs? Let's start with some context OSS at Square is mostly a happy accident. Jack hired Bob, who's job was attracking world class engineers, and he did that through talks & OSS.

Gradle now enables strict Gradle plugin validation for published plugins and automatically infers plugin id Both are requests that I've pushed for! docs.gradle.org/9.4.0-rc-1/r... Excited to see it land!

Okay, here's the plan: @liutikas.net will teach me how to profile Gradle configuration times, and maybe we'll fix something in kotlinconf-app! 24 hours from now: Thursday, 8am PT / 5pm CET twitch.tv/zsmb13 Mark your calendar for a reminder: addcal.io/e/5t99s5irjfqs

Hot take (?): for a significantly easier time, schedule your AGP 9 upgrades for about two months from now. There'll be a lot more materials and samples available to help you, and various issues will have been fixed by then.

Join us with @ParisAndroidUG at @amoamoamo HQ on Jan 13, 2026! 🚀 On the agenda: generating videos off-screen and off-main thread from Composables, why & how we switched from Hilt to Metro DI, and how to build your own Kotlin compiler plugin.

. @rickclephas.dev has done an amazing job maintaining KMP-NativeCoroutines (and related libraries) for so long. The Kotlin Multiplatform community owes him a huge debt of gratitude.

You shared that androidx libraries are constantly in alphas and we listened. In the past two years while adding a ton of new libraries we actually increased the percentage of libraries that are complete or actively developed. The combo of these two groups went from 64% to 76%. #androidx #androiddev

Compose 1.10 was released yesterday! 🔟 It includes some nice new features: 🧞‍♀️ Support for dynamic shared elements 👰🏻‍♀️ New Enter/Exit Transitions: unveilIn / veilOut ⏭️ Modifier.skipToLookaheadPosition() 📦 New retain APIs influenced by Circuit android-developers.googleblog.com/2025/12/what...

Made some updates to the Koog based AI agent functionality in the ClimateTrace Kotlin/Compose Multiplatform sample (github.com/joreilly/Cli...). It's now fully conversational (it had just supported single queries before)...credit to Koog CMP sample for inspiration. #KMP #CMP #AI

New blog post on how to render beautiful soft shadows projected by the user's finger with Jetpack Compose. www.romainguy.dev/posts/2025/f...

Yay, my first Koog PR merged....albeit small change to one of the samples 😀 github.com/JetBrains/ko...
