The new Jetpacker sample app integrates with Android's intelligence system using AppFunctions. Read this blog post for the down low. android-developers.googleblog.com/2026/07/buil...

Join @lojanda.bsky.social and me on this deep dive into the intelligence system and Android MCP using the AppFunctions API: www.youtube.com/watch?v=qtQM... #AndroidDev

Google I/O Connect Berlin was a wild ride, but the biggest highlight? Sitting down with @keyboardsurfer.dev to break down the brand-new Android AppFunction API. 🤖🚀 youtu.be/z1Ftq-Ju-ZU #AndroidDev #GoogleIO #GoogleIOConnect #Android16 #AI #MCP #Gemini #AppFunction

We just open sourced the AppFunctions Testing Agent! 🧪 Manual deterministic testing & LLM-based agent evaluation 📱 Clean multi-module refactor of ChatApp with Wear OS support! Grab your API keys and check it out. #AndroidDev #AI #FridayDeploy github.com/android/appf...

Want to know how fast it can be to integrate AppFunctions in your app? Watch the What's new in Android segment to see what you can do today. youtu.be/sig3n7XyaaA?...

AppFunctions unlock new ways to interact with your app's users through system agents. We're currently experimenting with the API surface. Watch the feature introduction, register your interest at goo.gle/eap-af and keep your eyes peeled for more to come very soon. www.youtube.com/watch?v=KvTR...

Numbers like these show time and again, that a little work on the right thing goes a very long way. @marianeum.bsky.social was very quick to update Monzo's R8 configuration and made the app much more performant along the way. ⚡️

Come and chat with us on Feb 5th 😊 we'll (try to) answer your questions about Gemini in Android Studio, and share some tips & tricks 👩‍🔬 With @josealcerreca.bsky.social, @astamato.bsky.social, @nosuid.bsky.social, Joe Birch and a few more! Join in → goo.gle/3O7dfk0

If you want to reduce your ANR rate... enable R8! 🥁 Honestly the numbers from Reddit here are wildly impressive, with 30% less ANRs, 40% faster app startup and frame rate improvement of 25% 😱 Checkout the video from @keyboardsurfer.dev to learn more! www.youtube.com/watch?v=QqO2...

Are you ready for a session on Android performance including some live coding? I mean, what could go wrong? Watch the recorded Google I/O 2025 session now! www.youtube.com/watch?v=xMyl...

At droidcon London @ajeshr.bsky.social and I presented on "low effort, high impact app performance". We explored how you can improve app performance and then measure these improvements. youtu.be/t7djyOWymJQ?...

Performance Spotlight Week is done and dusted. Check out everything we talked about in the closing blog post. android-developers.googleblog.com/2025/11/full...

We're hosting a live Ask Android session to cap off Performance Spotlight Week at 6PM CET / 9AM PT today. Tune in and bring your questions. www.youtube.com/watch?v=RMnZ...

During Google I/O 2025 we also talked about low effort and high impact app performance improvements. And now you can watch the recording.

Tomorrow 9AM PT we're going to answer your #AskAndroid questions on app performance. Quick think of something and ask right now! I won't answer before the session though. www.youtube.com/watch?v=RMnZ...

Run this and let me know the output: `grep "dontoptimize" app/build/outputs/mapping/release/configuration.txt` In case it's not empty, you definitely should watch this youtu.be/QqO2jZ-NZko?...

Customizing the cache window lets you prefetch content on Jetpack Compose LazyLayouts. Combining it with pausable composition and text prefetching is a winning combination.

Let's talk you through R8 Keep Rules, take the edge off and give your app the performance boost it deserves. android-developers.googleblog.com/2025/11/conf...

There's more to g-R8 performance. Profile Guided Optimizations, Jetpack Compose 1.10 and background work considerations are on the menu of today's read. android-developers.googleblog.com/2025/11/deep...

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...

Share this post with your stakeholders. I'm convinced they want to invest in performance after reading it. android-developers.googleblog.com/2025/11/how-...

This Friday we'll host a live session on App Performance. Bring your questions using #AskAndroid or #performanceEnabled. See you there www.youtube.com/watch?v=RMnZ...

The single biggest performance impact for the Reddit app came from enabling the R8 optimizer's full potential. android-developers.googleblog.com/2025/11/how-...

We're just starting a Spotlight Week on Performance. So get yourselves ready for some g-R8 content.

It's almost time for @droidcon.bsky.social London once again. www.youtube.com/shorts/rgC8z...

droidcon London is around the corner. This time Ajesh Pai and I will share how you can make low effort and high impact app performance improvements to your app and how that helps drive user satisfaction and business results. Looking forward to seeing you there.

Ever wondered how much app performance really matters? 🤔 Duolingo's latest case study shows it's a game-changer! They boosted their Daily Active Users by hundreds of thousands just by speeding up their Android app. 🚀 blog.duolingo.com/android-app-...

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?...

Our #IO25 talk on how to build more accessible apps with Compose is out! 🥳 Lots of tips on choosing appropriate semantics, merging, clearing & hiding, inspection & debug, accessibility checks in tests 🫶 Check it out ☺️ www.youtube.com/watch?v=80qk...

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

Come talk with us at the Dev Productivity booth after the Developer Keynote at #GoogleIO

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...

Awesome conversation about Android App Performance in the new Android Build Time podcast: www.youtube.com/watch?v=8zgN...

I used to struggle with too many tabs syndrome. Thanks to named browser windows this is a problem that has scaled up dramatically. To combat that, I'm currently going through tabs and browser windows like I'm Marie Kondo.
