If you release frequent updates to your Android app (more than every 2 weeks), please set up robust baseline profile pipeline otherwise most of your users will have poor app performance (see developer.android.com/topic/perfor...)

👋 Hey Friends! There's so much happening in the XR industry right now! #AndroidDevSummit is SOOO back! And we're gonna have a TON of XR content! 😎OH! Did I mention it's 2 events? 🇺🇸 -> rsvp.withgoogle.com/events/android-dev-summit-bayview 🇬🇧 -> rsvp.withgoogle.com/events/android-dev-summit-london

Keynote’s Magic Move is great - until you try animating code. I wrote about building smooth "Magic Move" code animations from first principles using TextMate grammars & Heckel's diff algorithm: rahulrav.com/blog/magic_m...

``` Upon reflection, I've come to believe that quality software is not about how many features something has or how quickly it is built but rather how cared for it is by the designers, developers, and product people who work on it. ``` This rings very true https://brettcodes.com/im-done-using-ai/

What a great podcast episode !

I published vibrance-0.1.0 on Maven, now with support for Compose for Desktop (JVM). The APIs let you mix colors yourself, or draw gradients as modifiers or Compose brushes. Next steps: refine the model training to improve some color transitions, better alpha support. github.com/romainguy/vi...

androidx.tracing 2.0.0 is now beta01. Updated documentation is at: developer.android.com/topic/perfor... Release notes is: developer.android.com/jetpack/andr... Happy tracing !

From 18 WPM to 100 WPM 💥 It took 51+ hours of practice, transitioning to a split layout, and a lot of patience, but I finally found my mechanical keyboard "end game" with the @keyboard.io Model 100. Read about the journey, and the stats at rahulrav.com/blog/keyboar...

Signed up for Deep Learning coursework; and as I am reading some recommended papers - I swear adjacent to a mathematical construct I think i know, is a rabbit hole that until now never existed. Oh, you want an integral on this marginal distribution; surely you must have heard of error functions. 😭

Sometimes what you need is a hybrid of an ArrayList and a LinkedList. (When your API allows adding things into a list like structure - think contextual data). BlockLinkedList that does exactly. Uses ART instrinsics for a fast reset and object pooling to minimize GC overhead.

Wrote up a blog post going over the "why" in each of the features in Perfetto v57. This is something I plan on doing for each release going forward (including dedicated posts when a feature is big enough to deserve it!) Find it at lalitm.com/post/perfett...

Installed Cauchy OS a few months ago on my Framework 16 and I must say, arch has been extremely delightful to use. Extremely grateful that I don't have to use Windows or macOS. It's really the year of Linux on the desktop!

Coming in Metro 1.3.0! Was awesome working with Rahul on this

My talk from Android Makers on the new Jetpack Multiplatform Tracing 2.0 library is now on YouTube! 🚀 🇩🇪 PS: I’m at KotlinConf this week! If you’re using the library (or curious about tracing / app performance), please say hi. I’d love to meet you and hear your feedback. youtu.be/d9Ya_YgDLOg

This is excellent, one of my favorite long-form pieces on agentic engineering - includes several non-obvious ways in which leaning on coding agents can catch you out

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

androidx.tracing 2.0.0-alpha04 is now available. Here is the release notes. Happy tracing ! developer.android.com/jetpack/andr...

If you are a parent always worried about waking someone up while watching TV, this headphone is just incredible 🙂 electronics.sony.com/audio/speake...

I will be speaking at Android Makers about the internals of the androidx.tracing library and how benchmark driven development ensures low overhead tracing. If you like tracing, profilers and benchmarks - this talk is for you! androidmakers.droidcon.com/2026/rahul-r...

Want to actually understand what your app is doing at runtime? In the next episode we explore: ⚡ Android Profiler 🔎 Perfetto 🧵 Tracing 2.0 📱 Performance in Compose With Rahul Ravikumar. Join us live → cwti.link/twitch #AndroidDev #Performance #JetpackCompose

I broke down how R8 strips away Intrinsics overhead and leverages ART intrinsics to make your apps faster—without you changing a single line of code (starting with AGP 9.0). rahulrav.com/blog/kotlin_...

PSA: Starting Android Gradle Plugin 9.0 (or the latest stable version of R8): R8 will automatically optimize all Intrinsics.check* APIs in Kotlin automatically ! This should greatly help improve app performance (especially Compose given the large Kotlin library API surface).

Given the state of Windows 11 + Copilot 🤮; 2026 might actually be the year of Linux on the Desktop. Framework 16+ Ubuntu has been a breath of fresh air.

Happy UniFi Travel Router day to those who celebrate it 🎉 store.ui.com/us/en/catego...

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