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...

This week's #JetpackReleaseNotes includes Window 1.5.0, Compose Material3 1.4.0 plus bug fixes in Compose 1.9.2, Navigation 2.9.5, Room 2.8.1, Sqlite 2.6.1, Wear Compose 1.5.2, and WorkManager 2.10.5. developer.android.com/jetpack/andr...

NavigationEvent 1.0.0-alpha09 makes some pretty sweeping changes to the API surface. - Dispatcher now focuses on global state with the new history and transitionState properties - Handler has local state - Compose users get a NavigationEventState for hoisting developer.android.com/jetpack/andr...

📢 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.

Tried to rebuild the Android 16 notification glue/magnet/expressive thingy. Next are the corner sizes. #androiddev #jetpackcompose

We're back from conference season with more #JetpackReleaseNotes including Wear ProtoLayout 1.3.0 (first Material3 release!) and Wear Tiles 1.5.0, bug fixes in AppCompat 1.7.1 (compat with Nav3!), Fragment 1.8.8, Lifecycle 2.9.1, and a new PhotoPicker library! developer.android.com/jetpack/andr...

Yesterday was my last day at Google. What started as a 2-year Green Card journey became 11 amazing years & meeting incredible people. So many great memories from creating Jetpack to adopting Kotlin. 10/10, would do it again. It is time to move on though, try new challenges and learn new stuff!

First time speaking at #KotlinConf, done and dusted! What an experience. That's a wrap, see you all next year!

@liutikas.net and Alan Viverette are on stage at #KotlinConf diving into "APIs: How Hard Can They Be?"

Welcome to #KotlinConf 2025!

The insight of a 10-chapter book, packed into a tight little blog post. The ‘fear’ advice slaps.

Lifecycle 2.9.0 is out today with a new lifecycle-viewmodel-testing artifact, SavedStateHandle going KMP, MutableStateFlow support for SavedStateHandle, plus new 'saved' property delegates on SavedStateHandle that use Kotlin Serialization. developer.android.com/jetpack/andr...

Navigation 2.9.0, Lifecycle 2.9.0, and SavedState 1.3.0 are out today along with a bunch of other #JetpackReleaseNotes including Core Telecom 1.0.0, DataStore 1.1.6 (fixing the 1.1.5 release!), and Compose 1.8.1. developer.android.com/jetpack/andr...

Today, we've released a brand new Jetpack library - Navigation3! A pure Compose, state based navigation library: android-developers.googleblog.com/2025/05/anno...

I'm proud of Gradle Best Practices finally launching. It was a result of many hours of discussions, negotiations, and wordsmithing to bring you the first batch of best practices. It was a deep collaboration between Google, Jetbrains, and Gradle. Enjoy it! blog.gradle.org/gradle-best-... #gradle

There is a new version of gradle-lint checks! developer.android.com/jetpack/andr... Give it a spin and share any feedback you might have! #gradle

Compose 1.8.0 is out today alongside a bunch of other #JetpackReleaseNotes including Transition 1.6.0 and bug fixes in DataStore 1.1.5, ExifInterface 1.4.1, Room 2.7.1, and WorkManager 2.10.1. developer.android.com/jetpack/andr...

One of my favorite helpers in SavedState 1.3 is the `saved` property delegates for any SavedStateRegistryOwner (e.g., ComponentActivity or Fragment): class MyActivity : ComponentActivity() { var selectedItem by saved { -1 } } No more manual save/restore! developer.android.com/reference/ko...

Room 2.7.0, the first KMP release, is out today! 🎉🎉🎉 Other #JetpackReleaseNotes include Core 1.16.0, Core i18n 1.0.0, long alpha releases going stable, Compose Material3 1.3.2, Compose 1.8.0-rc03, plus SavedState, Lifecycle, and Navigation going beta01. developer.android.com/jetpack/andr...

I wish the world had fewer Kotlin compiler plugins, not more 😭
