Our session for Adapting Android apps for #AndroidXR is now live! Learn how to build with the new Jetpack XR SDK and see your app come to life in the XR emulator within Android Studio. https://youtu.be/RQsE0n1xBxo?si=mQXjUYCFYPyYSkx-

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...

✨ New #JetpackCompose feature ✨ Introducing `keyframesWithSpline`, unlike the standard `keyframes` animation spec, it produces a natural smooth curve, perfect for working with predefined X,Y coords. ✂️ gist.github.com/riggaroo/98d... 📃 developer.android.com/reference/ko...

Do your teams work in public channels (which, as I understand it, is how folks at Slack itself work) or are your teams hiding their decision & investigation process in private channels, Apple style culture? I shared this with our mobile org recently (400+ people). #AndroidDev

🤔 Did you know... there is a new Modifier in town 🤠 The latest alpha version of Jetpack Compose contains a new `Modifier#animateBounds()` which can automatically animate the size & position of your Composable. Simple example usage: gist.github.com/riggaroo/202... #JetpackCompose

Cool to see Confetti (github.com/joreilly/Con...) Kotlin/Wasm based Compose for Web client running now in new stable Safari 18.2 release.

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...

If you do any Compose UI work you owe it to yourself to read this excellent post by @zachklipp.com blog.zachklipp.com/centering-in... Just like any of Zach's articles, there is so much good information in there, you will thank yourself spending the time understanding what is being explained in it!

Benchmarking is hard! This is a great example, let's dive into the diff to highlight what I'd typically surface if someone shared this benchmark at Square. The diff: github.com/android/nowi... (it's great that Arnaud shared the diff btw, too often benchmark authors don't) #AndroidDev

Yet another "My Droidcon London talk is out..." post :P Check it out if you're interested in how to think about and design a solid composable 💎 www.droidcon.com/2024/11/22/d...

OK, I sent out jetc.dev Newsletter Issue #242! Math! Shared element transitions! Custom modifiers! Macrobenchmark! Adapting to platform-specific design systems! And... why does wrapContentSize() not wrap my content size?!? jetc.dev/issues/242 #JetpackCompose #AndroidDev

I would like to share that I have released the Gradle Plugin of my svg-to-compose project! It is a #KMP project with its own parsing algorithm that parsers both SVG/XML to ImageVector (and, in the future, Canvas and VectorPainter) and it is available on Maven for usage! ⚠️ Long thread ahead.

So what should you do? Create your own RequestBody implementation instead of calling RequestBody.create() with the serialized bytes, and then perform the serialization lazily, only when RequestBody.writeTo(sink) is called (it's called from the http thread).

New release of Gr8 is the Gr8test so far! Includes a configurable R8 version and artifact transforms to deal with multi-release jar files.

I've published version 0.3.0 of my Kotlin Multiplatform bindings for Bluesky. The main highlight of this release is support for Jetstream to consume the Bluesky firehose. It supports all the features of Jetstream, including Zstd compression to reduce message sizes in transit.

And it's all open source! Feel free to try it out and let me know what you think!

I wrote about Kotlin scripting

This is a must read for Kotlin enthusiasts! Martin is on a journey to spread the word about how powerful Kotlin scripting is, especially due to some doubt generated from some recent news.

Good news! The Android 16 DP1 API differences report is fixed! So, I wrote up a bit more on "app functions": commonsware.com/blog/2024/11... #AndroidDev #AppFunctionsAreFunctionsForApps

Compose hot reload. KotlinConf app. Happening now. www.twitch.tv/zsmb13

Android 16 Developer Preview 1 is out! I attempted to do my standard "random musings" post, and, well... that did not work out quite as I had hoped: commonsware.com/blog/2024/11... #AndroidDev

Some news about Kotlin scripting blog.jetbrains.com/kotlin/2024/... I wonder if this breaks anyone's existing usage of it. I always found kotlin scripting interesting, but I rarely see anyone mention using it too much

Hey, I just released jetc.dev Newsletter Issue #241! Compose alphas! Compose Multiplatform patch! PaddingValues! Graphics layers! Swiping! Heatmaps! Navigation! And... why did we get a new production Compose BOM?!? jetc.dev/issues/241 #JetpackCompose #AndroidDev

To repeat the same yourself: - Install the app - Open Android Studio -> View -> Tool Windows -> Profiler - Run system trace and open in ui.perfetto.dev - Run method recording and open in profiler.firefox.com You might need <profileable> tag in AndroidManifest.xml to connect!

Let's look at Bluesky performance on Android! I managed to build a release build of the app and ran some traces, let's see what we can find... I have ~hour, will add to this thread as I investigate

Colors can also be difficult to work with because of psychophysical effects. For instance, saturation can affect brightness. In the image attached, all colored patches have the same luminance, but not the same brightness.

Hey #AndroidDev folks! Is there anything related to Broadcast Receivers + Jetpack Compose + app architecture that confused you or that you thought was unclear from the docs when implementing them in your app?

Here's a fun #AndroidDev architecture design problem: Implement a slider that edits state that is stored on disk. I think working through this task can reveal a lot of insight for why building great UI around asynchronous tasks can inherently be tricky and how tradeoffs are necessary.

For a lil more variety, I built the now in Android implementation, and packaged it into a library with other utility functions here: github.com/tunjid/compo...

Kinda hard to accept the terms when the terminal is "read-only" 😅

Folks doing #kmp, what's your approach for platform permissions on android/ios targets? Custom implementation, or libs? Which libs? going to tag #androiddev for reach (not sure how well that works here)

Compose now with... hot reload? This looks super interesting, check out this video www.youtube.com/watch?v=8Z-V... The code seems to be here github.com/sellmair/com... #AndroidDev #Compose

The latest #ComposeTip for Delightful UI has been released 🥳 In this episode, we play with a few of my favorite things: Graphics layers, BlendModes and ColorFilters 🥰 Check it out 👇 youtu.be/KawI7srRvOM?...

Colors can be a confusing for developers who haven't spent time understanding the (deep) topic of color management. The main misunderstanding is see is that the values of an RGB triplets are absolute. They are in fact *relative*.

Oh no, what did I do? 😅
