We have a new case studies page on kotlinlang with both KMP and server-side uses of Kotlin. When looking at KMP case studies, you can even filter by platform and by use of CMP! kotlinlang.org/case-... Next step: add all the other case studies we know of but didn't process yet.

Hey Android devs! Planning your next career move for 2026? Go beyond a single platform. We’ve launched #KMPLevelUp — a free 4-week journey to master KMP with curated courses, expert content, and a live webinar. Time to ship your Kotlin skills to iOS & web: jb.gg/vbl7v4

📢 Rare opportunity: my team is hiring! We're looking for a new Developer Advocate to cover server-side Kotlin, focusing on Spring. If you love Spring, Kotlin, and their communities, this might just be for you. Learn more and apply here:

Spoiler: you'll never wanna go back!

When you want to push your AR platform that virtually nobody cares about so much that you make an important app icon almost entirely unrecognizable

⏳ Just three weeks left to submit your talk for KotlinConf’26! 👉 https://sessionize.com/kotlinconf-2026/ “Don’t forget that we also accept lightning talks! If you feel like your content would have to be padded to fill a regular session, it might be more enjoyable as a lightning talk.” – @zsmb.co

I guess we're learning about bankruptcy in today's Kotlin lecture.

Compose Multiplatform 1.10 will bundle Compose Hot Reload, so you don't even need to set up the plugin separately! You can already try it in beta01:

Help us get a better picture of who uses KMP and CMP, and share your feedback about your experience with the team in the yearly survey:

Google doesn't want you to know about this one weird trick to have convenient, global access to Context in your apps!

The KMP IDE plugin is now available in every IDE and OS combination you might need! Now including Android Studio support on Windows and Linux. We'd also really appreciate some fresh reviews on it, as most reviews are complaints about availability 😅

If you're in Budapest on the 18th of November, join us for the next Android meetup!

One of the coolest things about Pixel phones is their Now Playing feature. Especially when it tells me confidently which song my toothbrush sounds like.

There's less than a month left to submit your talk ideas to KotlinConf 2026! Why not do it today?

pssst. a man of my word the first droidcon London talk is now live! we join @zsmb.co to learn about all things hot reload! youtu.be/gWlLGfbsHfk?... #dcldn25

The Android team has just released a brand new landing page for Kotlin Multiplatform, explaining the technology and showing how Google and JetBrains are support different parts of the ecosystem! developer.android.co...

Just finished my talk Blazing Fast UI Development with Compose Hot Reload 🔥 at #dcldn25! Slides and resources are shared here: zsmb.co/talks/blazin...

... Am I early?

We’re running our yearly Kotlin Multiplatform survey to understand how the ecosystem is growing, how our recent releases are performing, and where to focus our efforts next. Your experiences matter! Take a few minutes to share your feedback 👉 https://surveys.jetbrains.com/s3/KMP-Survey-2025-B

A macOS update isn't complete without it breaking custom screen savers, I guess... My blog post now includes a brief section on Tahoe, and I released a new patched version of the Kotlin Logo screen saver as well. Grab it here:

Kotlin 2.2.21 and 2.2.20 have a lot goodies in them. In my video, I'm looking at the highlights! www.youtube.com/watch?v=QWpp...

A new default project structure for KMP is in the works 🚧, replacing the all-in-one composeApp module with per-platform app modules and separate shared modules. The image below shows Android, iOS, Desktop, and Web apps that all use the same shared Compose UI. Feedback welcome!

If you're not on a Kotlin 2.x version yet: what's your blocker for upgrading?

Looks like Medium is down. ... In a way though, this page is actually a much better UX than what you usually get there.

Someone really needs to explain to me why "made for kids" content can't be added to a playlist on YouTube so I can find it again later. I swear I'm an adult.

Finally, we can set Project view as default in Android Studio. This is really nice if you develop Kotlin Multiplatform project in Android Studio 🛠️📱 #AndroidDev #Kotlin #KotlinMultiplatform #AndroidStudio #iOSDev

Curious ratio.

I'm super proud of this webinar for underrepresented communities to CFP for KotlinConf. It has been a goal of mine to have this type of encouraging event since I started at JetBrains, and now you can watch the video 🥰 www.youtube.com/watch?v=cTfH...

So... Is it still worth learning to code?

If you're interested in building your own AI agents, you should try the Koog framework that lets you do that in Kotlin! We now have a brand new landing page for it, too:

We released Compose Hot Reload 1.0.0-rc01 🎆 What started as a happy accident was promised to be pushed towards stability as quickly as possible, allowing you to rely on a stable user experience. github.com/JetBrains/co...

We just published the 1.0.0-rc01 release for Compose Hot Reload! With this, we are quickly approaching our first stable release. Have you tried Hot Reload yet? Let us know how it's working for you!

This continues to sound like an absolutely awful time. The changes give Google unreasonable control over all Android devices and brings everyone closer to the locked down Apple experience. The current Play verifications and warnings for untrusted sources should be enough.

Designers when an android engineer ask to just use the system back arrow: “our custom back arrow is an expression of our brand, we cannot yield to looking like a Google app” Designers when Liquid Glass looks like shit everywhere in their app: “LEROY JENKINSSSSSSS”

Have you tried incremental compilation for Kotlin/Native yet? If yes, did it work well in your projects? Did it cause any problems? To try it, add this to your gradle.properties: kotlin.incremental.native=true

macOS Tahoe doesn't exactly feel polished. (Besides the broken labels, it also just never finds a setting that Spotlight used to find correctly every time)

I still keep learning about cool new features in IntelliJ. The latest one: excluding imports when looking for the usages of something. So neat!

Say hello to hot reloading compose resources, supported from CMP 1.10.0-alpha01 🔥 Initially requested by @zsmb.co and @rakhman.info Thanks to Nikita Lipsky 😇

The next Android Budapest meetup is on Thursday! We'll be exploring Compose Hot Reload 🔥 and looking at JavaScript security issues with WebViews. RSVP now:

If for some reason you haven’t seen it yet, we released Koog — one of the most advanced frameworks for building AI agents! Targeting unmatched range of platforms: JVM backend, Android, iOS, JS, and WebAssembly #ai #java #kotlin #genai #llm #openai #android #ios #js github.com/JetBrains/koog

Koog, the Agentic AI framework for Kotlin that we're building at JetBrains, is, well, kind of cool. Especially since it's not designed for toy projects, but to ✨ scale ✨! Learn more: medium.com/@vadim.brili...

New language video! Value classes got significantly improved Java interop in Kotlin 2.2. Check out how it works:

aaaaaaaaaaah > Cannot invoke "Build_gradle.exec(org.gradle.api.Action)" because "this.this$0" is null

If you have feedback about *anything* around Kotlin, this is the time to have your voice heard in our annual Kotlin Developer Survey. The language, the tooling, the ecosystem, Kotlin Multiplatform, Compose... It's all in there! Takes just 10 minutes:

YouTube and Bluesky are in a heated competitionfor which one can be the worst app on my phone that I regularly use.

Being a developer advocate is forgetting what your IDE looks like with a normal zoom level and your preferred theme.

People who place takeaway orders at the airport food court... Where are you taking it?!
