Metro 0.13.0 adds top-level contribution providers, Circuit code gen, and a new @DefaultBinding annotation.
This also removes most deprecated APIs as Metro prepares to go stable (!!). If you have runtime API feedback, now is the time!

Snapshot of Compose "Snapshot" 🦢
Working on another snapshot feature for HotSwan, which captures a device screenshot after every successful hot reload and pairs it with code diff that triggered the reload. You can do Code Time Traveling (revert) to a specific snapshot moment.
Trying to navigate how serialization works with Nav3 routes in multiplatform? Check out these great new docs we just published: kotlinlang.org/docs/...
The answer was no, so I'm building this myself as v2 of github.com/saket/swipe. Here's a first draft:
Just released the initial version of Snappy Swipe, inspired by Material 3 Expressive notifications.

Custom View Preview deprecation.
The Android Studio team is deprecating the Custom View Preview feature in the coming releases. If you're still using Views, it's really time to shift to Jetpack Compose.

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.
Given this, calls for boycotting Square OSS are stupid.
It's disrespectful to the hard work all these ex-Square engs have done. It won't hurt Square the company in any meaningful way, it just makes a bunch of your Android peers sad.
What happens to Square / Block Android OSS projects post layoffs?
Let's start with some context
OSS at Square is mostly a happy accident. Jack hired Bob, who's job was attracking world class engineers, and he did that through talks & OSS.
Gradle now enables strict Gradle plugin validation for published plugins and automatically infers plugin id
Both are requests that I've pushed for!

Excited to see it land!
If you're using convention plugins and updating to AGP 9, check out this page that shows how to use the latest APIs:

AGP9 is sooo 2025!
New page for your 2026 Gradle project isolation tracking from @pablobaxter.com !

Okay, here's the plan: @liutikas.net will teach me how to profile Gradle configuration times, and maybe we'll fix something in kotlinconf-app!

Mark your calendar for a reminder: addcal.io/e/5t99s5irjfqs
Hot take (?): for a significantly easier time, schedule your AGP 9 upgrades for about two months from now.
There'll be a lot more materials and samples available to help you, and various issues will have been fixed by then.
Not sure who else needs to hear this but an OSS maintainer taking the time to privately give you a warning is doing you a massive favor
Join us with @ParisAndroidUG at @amoamoamo HQ on Jan 13, 2026! 🚀
On the agenda: generating videos off-screen and off-main thread from Composables, why & how we switched from Hilt to Metro DI, and how to build your own Kotlin compiler plugin.
. @rickclephas.dev has done an amazing job maintaining KMP-NativeCoroutines (and related libraries) for so long. The Kotlin Multiplatform community owes him a huge debt of gratitude.

You shared that androidx libraries are constantly in alphas and we listened. In the past two years while adding a ton of new libraries we actually increased the percentage of libraries that are complete or actively developed.
The combo of these two groups went from 64% to 76%.
