Hunting down Jetpack Compose recomposition issues manually is a huge time sink I’ve spent the past few weeks using @mmckenna.me’s Dejavu to simplify this: - Write Dejavu tests to establish a baseline - Tell the agent to hunt for issues and A/B fixes - Profit

🤖 I've just open-sourced a new set of skills, covering Kotlin, Compose and Android development. Very early days, but it covers a lot of things which crop up in code review regularly. github.com/chrisbanes/s...

💠 Haze 2.0-alpha01 is out! This is a big release, splitting Haze up into layers, with the goal of enabling pluggable visual effects. Let me know what you think! chrisbanes.me/posts/haze-2...

Starting hacking on an AI Agent orchestration tool (for myself). Decided to build it in Rust (because why not), and holy cow: the entire CI run takes ~40 seconds, and most of that is setting up the toolchain. github.com/chrisbanes/e...

✨ ChromaDial is a new #ComposeMultiplatform library that enables you to create beautiful Dials for your #JetpackCompose app Its API is similar to the Slider, but instead works in degrees Just pass in and set the degree state #buildinpublic

After becoming infuriated by Codex (the tool) lately, I've switched to @mariozechner.at's `Pi` and it's like a breathe of fresh air 🧘 All of the stuff I actually use, it's super fast, and most importantly it doesn't constantly ask permission to run `git` shittycodingagent.ai

If your engineering team is 'senior-only' + AI-assisted… where do tomorrow's seniors come from? New blog post on the 'disappearing middle': chrisbanes.me/posts/disapp...

Tried out @github Copilot to write a small feature for Haze, all from my phone. It’s the ultimate in lazy programming, but I’m pretty mind blown. 🧵…

I've been looking into Liquid Glass details (experiment for Haze), and stumbled across this article by @kubekhrm.bsky.social. Simply wow. kube.io/blog/liquid-...

As a little experiment I asked Gemini 2.5 (Pro) to compare itself to ChatGPT-5. It ended up telling me about Gemini 1.5 and that “Google has not announced a Gemini 2.5 model.” I think I’ll be sticking with ChatGPT… g.co/gemini/share...

My team is looking for a new Android + KMP engineer! 🇺🇸/🇨🇦 Looking for someone in Boston, New York, Toronto, Washington DC 📺 Working on Ventura TV OS (www.thetradedesk.com/ventura-stre...) If you have any questions, feel free to ask! 🔗: careers.thetradedesk.com/jobs/4870331...

Looking forward to being back at @droidcon.bsky.social London this year. I spent quite a while on this talk title…

I migrated our entire codebase over to it last week, and we’re now fully on the Metro train. 💺 It has pretty much everything y’all will need, right now.

I don’t know how they expect anyone to know the location of this bar…

What is it with Facebook adding pull-up gestures for the most random actions: Instagram DMs: Pull up to toggle disappearing messages. WhatsApp: Pull up to call. The amount of times I’ve triggered these actions: too many. The amount of times that I’ve meant to perform them: absolutely zero.

I've been trying out @jetbrains.com Junie over the past few few days, and have pretty blown away with it. I've managed to do everything from a complex refactoring of Haze (with follow up tasks), to fairly complex string manipulation (pretty printing data class toString).

Seems to be a lot of talk about Haze and Liquid Glass… At its core, Haze is a background content transform library, and the ‘visual effect’ (blurring, etc) is just an implementation detail. Liquid Glass will be a runtime shader like others which Haze already uses.

💠 Haze 1.6.0 has been released! This is a big release: 🤖 Blurring for all versions of Android 🎨 Foreground (content) blurring 📐 Blurred edge treatment 🔗: github.com/chrisbanes/h...

💠 Haze 1.6.0-beta01 has been released! 🐛: Android 12 is now enabled by default 🤖: Experimental blurring support for all Android versions The video below is recorded on a Pixel 3 running Android 11, but it works back to Android 5. Please give it a try and report back! 🔗: github.com/chrisbanes/h...

Dug out an old Pixel 3 today, to do some testing on earlier Android versions. I forgot how small and light devices used to be. Feels like a feather compared to my iPhone Pro Max 16

Had a little hack getting Haze working on older Android devices. It uses RenderScript, so is never going to be real-time, but the lag isn't too bad. Everything is performed asynchronously, so this isn't jank. I'm undecided whether to keep going with it. Let me know if this would be useful to you.

Focus bugs in Compose are the absolute worst. The system is so opaque and hidden, that trying to deal with them is borderline impossible.

Haze 1.5.0 has been released: 💨 Optimised blur shader implementation (thanks to Kyant) 🖌️ New: HazeProgressive.Brush for custom progressive effects 🐛 Usual load of bugfixes github.com/chrisbanes/h...

🪢 Multiplatform Strings This blog post talks through a solution which we've landed on, using a single file as the source of truth for all strings, across all of our apps. chrisbanes.me/posts/multip...

🚀 Should you use Kotlin Sequences for Performance? I have always thought that using asSequence() was the way to optimize chained operations in Kotlin. But after benchmarking, the results shocked me: Sequences are often slower! 😱 #Kotlin #AndroidDev chrisbanes.me/posts/use-se...

Spent 10 mins integrating Bluesky comments into my Hugo blog Shamelessly reusing @kau.sh’s code from bsky.app/profile/kau....

Just tried asking ChatGPT and Gemini to convert a `composed` modifier to use `Modifier.Node`, and both failed miserably. Gemini probably got closest of the two, but it hallucinated all sorts of random callbacks which don't exist.

Haze 1.3.0 has been released! 🔵 Radial Progressive (gradient) effects 🖌️ Brush support in tints 🧑‍💻 New samples 📑 New docs courtesy of @markallison.social github.com/chrisbanes/h...

Big +💯 to this However, the same can be said about AndroidX bumping up the compileSdkVersion

💠 Haze 1.2.0 has been released The big change in this release is that it now supports overlapping blurred areas. 🔗: github.com/chrisbanes/h...

I'm thinking about renaming the modifiers in Haze but not quite sure what to use. If you want to help, you can comment here: github.com/chrisbanes/h...

💠 Here's a sneak preview of something that I've been working on in Haze: overlapping areas With this you'll be able to implement those classic glassmorphic card effects. I still need to run the performance benchmarks, but it seems to be working nicely... 🔗: github.com/chrisbanes/h...

Here's the slides from a talk I gave at work about Haze. There's no recording or anything, but the slides should hopefully be self-explanatory chrisbanes.me/talks/haze-t...

Haze 1.1 💠 has been released! The main change is the new 'Input Scale' parameter, which allows you to set an optional (down)scaling mode. This should have a positive effect on performance when enabled. github.com/chrisbanes/h...

12x difference between the top and bottom quartiles (for WFH) is eye opening. Even for in-office, that difference is 5x.

Opened up Keynote for the first time, in what feels like forever. Hello my old friend. Where's that Magic Move button again?

After what feels like a lifetime of development, I've decided to deprecate and archive Tivi 🫡 github.com/chrisbanes/t...

Haze 1.0 💠 has been released! This is a big release, not only because of the version number, but also because of the amount of changes since the latest stable release. You can read more below: chrisbanes.me/posts/haze-1...
