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

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...

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.

To demonstrate how the various new FlexBox properties affect layout behavior, I created a little visualizer experiment: sanbeiji.com/experiments/... Try adding items, messing around with the property values, etc., to see how things change! Example code changes appear at the bottom.

And we're off to the races! The Year of the Horse Android figures I designed are now up in my shop! shop.deadzebra.com Happy 🌝 New Year everyone! #ArtToys #Android #AndroidDev #LunarNewYear

It is the year 2026, people are still confused about compileSdk and targetSdk. (e.g. you can have targetSdk that is higher than compileSdk) www.liutikas.net/2026/02/13/R... Maybe this will explain it a bit more. #android

The new major version of androidx.tracing is now available on Google Maven. We’ve spent the last year optimizing it, so it's extremely low overhead. The documentation is available at: developer.android.com/topic/perfor... Happy Tracing!

It was such a cool event! It was an honor to help with judging, and it was great to see folks bringing their creativity and talent to build experiences on #AndroidXR with #Gemini

Protesters chanting "We're not cold, we're not afraid, Minne[apolis/sota] taught us to be brave" in Boston tonight outside Government Center station.

I'm seeing more and more instances of "we don't look at compiler output, so when LLMs generate code, we don't need to look at the output" LLMs are not compilers. With a compiler, you provide a highly detailed spec and know exactly what you are getting.

👀 Want to see a preview of what's coming up in #JetpackCompose? We heard you that debugging shared elements is tricky. In 1.11.0-alpha03, a new composable LookaheadAnimationVisualDebugging was added. Wrap your SharedTransitionLayout to add visual cues to track down those hard to debug issues. 🐛⤵️

I will be presenting at Droidcon London this year to talk about Tracing, and Perfetto ! If you are interested in Perfetto, or App performance in general - this talk is for you. If you would like me to cover something specific, please let me know and I promise to try.

Since we're doing this... I'll be giving a quick introduction to shaders and how they work. It's a topic that really excites (and scares, a bit) me, lately. I hope it'll get y'all excited too :) But not scared. Even though it's halloween.

I'm excited that Jay and I will be speaking at @droidcon.bsky.social London 2025 about Android XR. It would be great to see you there if you can attend!
