Android is now Compose First, we recommend you build all Android UI with Compose and `android.widget` is now in maintenance mode. #GoogleIO #AndroidDev android-developers.googleblog.com/2026/05/andr...

Android CLI is out! 🎉 Easy access to Android documentation and skills, in whatever agent you use. Plus we've made the initial environment set-up and project creation much more token efficient. What features would you like to see next? android-developers.googleblog.com/2026/04/buil...

In the next version of AGP - R8 makes coroutines 2x faster

Starting to look around for what's next. A bit of info on me and what I'm looking for chrishorner.codes/hire/

Unexpected benefit of vibe coding I've never been able to listen to music while coding, but now I can, because all I do is click allow over and over again

Here's the new page about the new stack traces in Compose, in case you were wondering how it all is supposed to work: developer.android.com/develop/ui/c...

This release also adds support for Compose stack traces that work with minified apps! (requires R8 and Kotlin 2.3.0+)

Jetpack Navigation 3 is stable! 🎉🎉🎉 Leaning into Jetpack Compose and the idea of combining smaller building blocks together really helped make Nav3 a much more flexible library that made it a joy to work on and hopefully for you to use as well! android-developers.googleblog.com/2025/11/jetp...

So you enabled R8. Now is a good time to catch up on Keep Rules. @ajeshr.bsky.social talks you through configuration and troubleshooting. www.youtube.com/watch?v=A0I6...

Try Gemini 3 in Android Studio! android-developers.googleblog.com/2025/11/gemi...

My talk on Navigation 3 from #dcldn25 is live (very impressive publishing from the droidcon team!). www.youtube.com/watch?v=j1Oi...

🆕Yesterday we published updates on #KMP on d.android.com/kmp! We finally have the Jetpack libraries that are compatible with KMP .. and CMP! Want to get into KMP? We have a course goo.gle/kmp-course. Pros can check their skills in the quiz at the end 😁.

If using Gemini in Android Studio is not your cup of tea, you can now use whatever model you want via API key! Now available in latest canaries developer.android.com/studio/gemin...

We launched the Androidify app on Google Play! Download it now, and create your very own custom Android bot ❤️ I've had loads of fun creating and testing the app - now you can too! play.google.com/store/apps/d... #Androidify

This Compose release is stacked! There is something for everyone in here 🎁 android-developers.googleblog.com/2025/08/what...

Documentation 📃 for Room KMP just got upgraded. It finally contains all the information on how to set it up, how to migrate from Android-only and even what features are (unfortunately) not available in KMP. Give it a go! 🟢 d.android.com/kotlin/multi...

Shreyas Patil wrote a nice article about Pausable Composition! We have been working on designs for this feature for quite a while until Leland asked "Why don't we just skip?". Ben Tengrove did a prototype to prove it would work and voila a feature is born. blog.shreyaspatil.dev/exploring-pa...

If you do, I would recommend using your own Gemini key to get a larger context (1m tokens) developer.android.com/studio/previ... And yes, there is a rather generous free tier for the Gemini APIs, too ai.google.dev/gemini-api/d...

I was barely online during KotlinConf 2025, so here's my follow-up now. Thank you so much everyone who joined us, in person or online. It was an incredible experience connecting with the community! ❤️ Here are some highlights of news below, as you've probably missed some! 🧵

If you're new to #KMP we have 2 new codelabs: 1️⃣ Get started - goo.gle/kmp-get-started-codelab 2️⃣ Migrate Room - goo.gle/kmp-migrate-room-codelab Try it out, let us know what you miss! 🤖🍏 Thanks to everyone that attended the code-along at #KotlinConf 😊

There are a lot of amazing KMP talks coming out right now but here is our talk from I/O! Dustin and I give an update on our latest KMP releases and then explain the build setup for an Android KMP app. youtu.be/gP5Y-ct6QXI?...

Tomorrow we will show how to measure and improve app performance at #GoogleIO. Make sure to join in.

Today, we've released a brand new Jetpack library - Navigation3! A pure Compose, state based navigation library: android-developers.googleblog.com/2025/05/anno...

#io25 is a go! Excited to be here for the first time as a Googler! Find me at the Androidify booth for most of today 👀

I am looking forward to KotlinConf 2025. I hope to see you there. Do drop by for the talk by @alanv and I on "APIs: How Hard Can They Be?" #kotlinconf

Don't use Gson on Android. Use Kotlin Serialization instead. It relies on code generation instead of reflection. This helps avoid optimization related crashes and faster app performance. github.com/google/gson?... github.com/Kotlin/kotli...

🚀 Big news for Android devs using Jetpack Compose! Media3 just dropped version 1.6.0, and it includes a brand new artifact: media3-ui-compose! Finally, seamless and customizable video playback directly in your Compose apps. 🎬 #AndroidDev #JetpackCompose #Media3

If you're running Macrobenchmark tests to compute interaction latencies, you should check whether the distribution of results is a normal distribution. If it's not normal, compare outlier traces with traces that are close to the median and you will find systemic perf issues! Thread 🧵 #AndroidDev

Been working on a new experimental Kotlin Multiplatform Tracing library capable of emitting Perfetto compatible traces. Currently supporting Android and JVM with the goal of eventually supporting other platforms. Here is the README if you want to try it out. github.com/androidx/and...

I keep seeing people talking about Cursor and how amazing it is. I tried it out on a SvelteKit app and most of the code it generates is completely wrong and not helpful. Is this a free trial issue and paid models are better? Any suggestions? It is using claude3.5-sonnet

A 🧵 announcement: With the Jetpack Compose 1.8. beta01 release, you may notice that a significant number of APIs that were previously experimental, have been graduated to stable.

The Android UI & Jetpack Compose team is building a new team in Bengaluru! Join us in building exciting new APIs for Jetpack Compose as well as the other UI libraries and help us expand to Bengaluru. EM: goo.gle/4gt9dMl SWE: goo.gle/4dQb9w7 PM: goo.gle/compose-pm-in DevRel: goo.gle/3DE8B7T

Android 16 will have some big changes around restricting orientation and aspect ratio by respecting the user's preferred orientation in more cases. Apps can no longer rely on assuming they have a specific aspect ratio to render in. For more details: android-developers.googleblog.com/2025/01/orie...

Nice new addition in AndroidX Activity 1.10.0 🥳 developer.android.com/jetpack/andr... #AndroidDev

Ok this one was truly 🤯

Benchmarking can be tricky! In this blog post, I show an example of how easy it is to get the wrong results and how to fix it: www.romainguy.dev/posts/2024/y...

All stars point to improving app performance this season. 🌟 Let Reddit's big Ws show you the way. android-developers.googleblog.com/2024/12/redd...

I wrote all these fancy interpolation, gradient and distance functions for Pair<Int, Int> and then realised they were not needed. Maybe they will come in handy another day! #adventofcode

I am looking for opportunities in Europe. If you're hiring for senior Android/KMP roles, let's get in touch. In industry for 13+ years (mostly in Android), working with KMP for ~6 years, led KMP in my current org with 200+ m users. Will need Visa and relocation support.

Hello regex my old friend(?) #adventofcode

I've completed "Red-Nosed Reports" - Day 2 - Advent of Code 2024 #AdventOfCode Pretty easy to brute force out, but I feel like there is probably a more optimal way to do part 2 github.com/bentrengrove... adventofcode.com/2024/day/2
