Jetpack Navigation 3 is stable! 🎉🎉🎉 Leaning into Jetpack Compose and the idea of combining smaller building blocks together really helped make Nav3 a much more flexible library that made it a joy to work on and hopefully for you to use as well! android-developers.googleblog.com/2025/11/jetp...

In other Navigation news, Navigation3 hits its 1.0.0-rc01 this week, which means we're almost to the first stable release! This is the perfect time to test it out one more time and make sure everything is working for what you need! developer.android.com/jetpack/andr...

The first #JetpackReleaseNotes of November include SplashScreen 1.2.0, SavedState 1.4.0, Navigation 2.9.6, RC releases in Navigation3, NavigationEvent, Activity, and Lifecycle and Compose 1.10.0-beta02. developer.android.com/jetpack/andr...

I got a bunch of questions about it, so I wrote a post www.liutikas.net/2025/11/02/U...

If you are using Gradle configuration cache you know that one of the most frustrating parts of the experience is unexpected CC misses. I wrote a post on how to minimize that! www.liutikas.net/2025/09/30/I... #gradle

Been using this as my daily Bluesky client on Android, even in early access it's fantastic (and the animations are stunning). Props to @tunji.dev for the awesome work in @heron.tunji.dev!

Designers when an android engineer ask to just use the system back arrow: “our custom back arrow is an expression of our brand, we cannot yield to looking like a Google app” Designers when Liquid Glass looks like shit everywhere in their app: “LEROY JENKINSSSSSSS”

Navigation3 1.0.0-alpha10 improves rememberNavBackStack's KMP support, breaks Scene APIs into its own package, & we've broken two layers out of NavDisplay in rememberDecoratedNavEntries (for multiple back stacks) and rememberSceneState (for owning system back). developer.android.com/jetpack/andr...

Just published "IDEA Vim". marcellogalhardo.dev/posts/idea-vim #AndroidDev #VIM #IDEA

📢 The Kotlin 2.2.20 release is out, bringing important changes for web development! Kotlin/Wasm is now Beta, with improved exception handling in JavaScript interop, npm dependency management, built-in browser debugging support, and a new shared source set for js and wasmJs targets. 🔗 kotl.in/2.2.20

Today's #JetpackReleaseNotes includes Camera and Camera ViewFinder 1.5.0, Room 2.8.0, Hilt 1.3.0, plus bug fixes in Compose 1.9.1, Navigation 2.9.4, and Navigation3 1.0.0-alpha09. developer.android.com/jetpack/andr...

I've seen a number of folks working on Gradle plugins struggle with writing a plugin that builds on top of another Gradle plugin, so I wrote a short post that talks about some of the gotchas in that work. www.liutikas.net/2025/09/04/G... #gradle

Love seeing this! Great example of what's possible with the NavigationEvent APIs. If you get a chance to try them out, we'd love to hear your thoughts on the APls. #AndroidDev #Kotlin

With Compose Runtime 1.9.0, the gates were open for many of the -compose integrations across Architecture Components to support more platforms including JVM, Native, and Web support now available in Lifecycle 2.9.3, SavedState 1.3.2, Paging 3.4.0-alpha03, and Navigation3 Runtime 1.0.0-alpha08!

Today's #JetpackReleaseNotes include Wear Compose 1.5.0 (the first stable release with Material 3 Expressive), more KMP targets in Lifecycle 2.9.3, SavedState 1.3.2, Paging 3.4.0-alpha03, and Navigation3 1.0.0-alpha08 plus the first Material3+Navigation3 alpha! developer.android.com/jetpack/andr...

I have capacity for maybe 1 casual mentee. If you are a junior dev in Android/Build/Tooling space and you are serious about wanting some advice/tips, reach out!

My old Android take-home tests on GitHub are awful. I wouldn’t have hired me back then (glad someone did!). I was lucky to meet @walmyrcarvalho.com.br and Brazil's AndroidDevBR community, who gave their time and knowledge freely. We all start somewhere.

🚀 One thing I’m really enjoying in these latest Compose releases: new Owner APIs for Compose! NavigationEventDispatcherOwner, LifecycleOwner, and SavedStateRegistryOwner (via SaveableStateHolder/Provider). It’s nice to have first-class tools to create and control Owners in any Compose subtree!

💡 NavigationEvent's Passive Listeners API lets you pass custom context with NavigationEventInfo and observe predictive back gesture state and progress **anywhere** in your Compose UI - perfect for coordinated animations without the extra wiring.

💡 rememberSerializable (aka rememberSaveable + KotlinX Serialization) is now stable! 😉 Try it out and tell us what you think! cs.android.com/androidx/pla...

45 more library updates are part of today's #JetpackReleaseNotes including Compose 1.9.0 going stable, Core 1.17.0, bug fixes in Fragment 1.8.9 and Media3 1.7.1, Room 2.8.0-rc01, Hilt 1.3.0-beta01, the first Compose 1.10.0-alpha01, and minSdk 23! developer.android.com/jetpack/andr...

Just a note to fill feature requests for these type of things if you find yourself building them - I was shocked that no one had ever actually filed a feature request for this on the issue tracker. Maybe we're missing a whole bunch more of these kinds of helpers? Don't suffer in silence 😭

Lifecycle 2.10.0-alpha01 is also out today with new Compose APIs to create nested Lifecycles (e.g., only allowing the current page in a HorizontalPager to be RESUMED) as well as CreationExtras improvements and nullable support for saved {} developer.android.com/jetpack/andr...

Today's #JetpackReleaseNotes include Benchmark 1.4.0, Browser 1.9.0, Security Crypto's final deprecation in 1.1.0 stable, bug fixes in Navigation 2.9.3 and WorkManager 2.10.3, Compose 1.9.0-rc01, new alphas for Lifecycle+SavedState, plus a ton of XR updates! developer.android.com/jetpack/andr...

A recent discussion has led me to realize that many folks do not fully grok the parts of Gradle that can be made parallel. By default almost all of Gradle runs in a serial way. So I wrote a post about it www.liutikas.net/2025/07/29/P... #gradle

I wrote about new Gradle phases added by the configuration cache feature and how the cost of them can be minimized. www.liutikas.net/2025/07/24/N... #gradle

Today's #JetpackReleaseNotes include more KMP platform support in Lifecycle 2.9.2 and SavedState 1.3.1, bug fixes in Navigation 2.9.2 and TV Material 1.0.1, Compose 1.9.0-beta03, and new tools to migrate to Bundled SQLite in Room 2.8.0-alpha01. developer.android.com/jetpack/andr...

New KEEP on name-based and new positional-based destructuring for @kotlinlang.org has just dropped! github.com/Kotlin/KEEP/...

I'm on vacation, but the #JetpackReleaseNotes don't stop! Navigation 2.9.1 fixes an important Lifecycle issue, Hilt 1.3.0-alpha02 decouples hiltViewModel() from Nav2, Paging 3.4.0-alpha01 adds more KMP platforms, and more! developer.android.com/jetpack/andr...

More #JetpackReleaseNotes are out today with bug fix releases in Room 2.7.2, WorkManager 2.10.2, and Compose 1.8.3 alongside Compose 1.9.0-beta01 and brand new Compose integrations in Ink 1.0.0-alpha05 and NavigationEvent 1.0.0-alpha03. developer.android.com/jetpack/andr...

Take control of your app’s navigation with Jetpack Compose Navigation 3. → goo.gle/3SGOp9Q Built from the ground up for Compose, Nav3 lets you manage the back stack, extend beyond a black-box library, and combine small components to create complex flows.
