One underrated improvement Metro brings is its easy setup. No more configuring KAPT, runtime modules, keeping versions in sync, etc. You apply the Gradle plugin, setup a tiny graph and the rest is driven through constructor injection, @ContributesBinding and its other features. This was all I needed

Actually, OpenJDK 25 is 18% faster than OpenJDK 17 and 21 and a whopping 84% faster than OpenJDK 11. Upgrade now!

I recently migrated our codebase away from Ktlint to Ktfmt and Detekt. I summarized the reasons and migration steps in a blog post: engineering.block.xyz/blog/adoptin...

Kotlin compiler plugins are amazing! ✅ Expressive syntax ✅ Compile-time checked ✅ Fast at runtime

Cash Android has recently switched to Metro, a new, fast dependency injection framework built for K2. That was a fun project and we're really happy with the results! Sharing details on how we approached the migration to help teams adopt Metro: code.cash.app/cash-android...

This is fantastic and @zacsweers.dev deserves all the praise but it also is gonna give you a false idea of what Z is like as a maintainer and author, what the project is like, and how you might achieve something like this yourself

After three wonderful years at Amazon I'm happy to share that I started this week at ... Square / Block again on my old team 🪃 I'm excited to think about developer productivity more deeply again.

Our KMP framework App Platform now supports Metro out of the box: github.com/amzn/app-pla... @zacsweers.dev is pushing the boundaries with Metro and there are still some Kotlin compiler bugs that need to be resolved, but on the JVM / Android it works.

I've been using ktfmt over KtLint for a few months for some projects. It's a blessing and so much easier to deal with. I forgot how much I missed 2 space indent in Kotlin. facebook.github.io/ktfmt/

We published a new version of App Platform with back button support. We also added recipes for saving presenter state, app bar integration and backstack navigation. Working with Compose in the business logic (Molecule) and UI (Compose Multiplatform) is so much fun. amzn.github.io/app-platform...

Anvil was quite successful inside and outside of Square, but now it's time for the next big improvement. Metro is 95% of what I pitched as Dagger 3 within Square. I'm excited.

Version 0.34.0 of the gradle-maven-publish-plugin finally comes with configuration cache support. Dropping support for Sonatype OSSRH unblocked us from waiting for Gradle to resolve the underlying issue on their side. github.com/vanniktech/g...

I had problems upgrading to the latest version of IntelliJ IDEA and Android Studio with the new Kotlin Multiplatform plugin. But now that it's working and Compose Hot Reload is running the integration is pretty nice. (This was my issue: youtrack.jetbrains.com/issue/KMT-11... )

This is great. Unlimited PTO is a trap. Amazon works very similar to Bolt and learnt to like this a lot. www.kron4.com/news/technol...

The new version of App Platform is out with support for Wasm! The wiki has integrated the Wasm sample application from the repository to see the code in action. amzn.github.io/app-platform/

I uploaded the slides of my presentation. Thank you all for coming 🙏 ralf-wondratschek.com/presentation...

The problem was very well summarised and the solution well explained. Great talk!

Kotlin Conf is great and a lot of fun. I'm closing today with my session "Scale your Kotlin Multiplatform projects using dependency injection". I hope some folks are still around and don't travel home yet 😊 kotlinconf.com/schedule/?da...

Indeed, we improved every parts of ADB Wifi pipeline. Besides support in Studio, you need ADB 36.0.1 (to be released soon) and Android 16.

I'm waiting for the AI agents from German companies named Günther, Jürgen or Klaus.

Where does one start with improving Android app performance? Should I start with writing benchmarks to establish a baseline? Should I enable StrictMode and LeakCanary first? How can I implement metrics in production? Are there any good guides for beginners you'd recommend?

That's me! I'm really excited about this topic and look forward to giving this talk at KotlinConf. I'll summarize how we got here and how painless dependency injection can be.

App Platform Launched App Platform is a lightweight application framework for state and memory management suitable for Kotlin Multiplatform projects. I'm happy to announce that we open-sourced the project today! amzn.github.io/app-platform/

This is fantastic. This is so close to what I wanted Dagger 3 to be when I proposed this 5 years ago at Square. Well done @zacsweers.dev 🙏

The hardest problem in software engineering is finishing migrations and it’s not even close

I was at @evernote.bsky.social when they started migrating to React Native in 2018. Against all advice from tech leads the SVP of engineering (coming from Amazon) pushed through. The quality of the Android app went downhill over the years not only performance wise.

Oh no, the bots are here.

Just migrated the BikeShare #KMP/#CMP sample (github.com/joreilly/Bik...) to use kotlin-inject-anvil (had been using just kotlin-inject)....think maybe can be simplified further but still got rid of quite a bit of boilerplate code (particularly related to setup of Circuit factories)

🎧 new episode #253 is out! logcat - a new look at logging with @p-y.wtf from Square. Listen here: fragmentedpodcast.com/episodes/253/ #AndroidDev #Podcast

This is a great summary, thanks for writing it down!

I'm in awe.

🎧 Episode #252 of Fragmented is out. Everyone needs a starter template! We also talk to @zsmb.co from @jetbrains.com about #Amper (their new build & config tool). Listen here: https://fragmentedpodcast.com/episodes/252 #AndroidDev #Podcast

It's easy to think every #dev should maintain a blog, contribute to open source and have multiple side projects on the go. You can be passionate about tech without doing any of those things. As a father, husband and full-timer, I barely have time to brush my teeth sometimes, let alone all that

Oh hey, I actually have something to post - we recently released KotlinPoet 2.0! code.cash.app/kotlinpoet-2...

@kau.sh and the Fragmented podcast are back! I'm truly honored to be part of the first episode and look forward to seeing where Kaushik will take the show.

Today is November 11, 2024-11-11 and I published version 0.1.1 of a library internally. Coincidence?

Just published version 0.2.0 for AT Protocol Kotlin Multiplatform bindings, includes a few goodies and also pulls in the latest upstream API changes. Also big thanks for @emplexx.emi.moe for their contributions to better handling for unknown enums! Sealed types ftw

This week we removed Dagger 2 and Anvil entirely from our project and replaced them with kotlin-inject-anvil. The APIs are so similar with each other, that it didn't make sense for us to support both anymore. #AndroidDev github.com/amzn/kotlin-...

Coil 3.0 is out now! The main feature of this release is full Compose Multiplatform support, but there are tons of other smaller improvements. Check it out! colinwhite.me/post/coil_3_...

That was easy!

The most annoying thing about Bluesky so far is that when I refresh my feed on the Android client, then it doesn't preserve the scroll position of the current item, but scrolls to the top instead.

👋 New on #Bluesky. I'm a software engineer at Amazon with a strong focus on Kotlin Multiplatform over the last year. While our focus is on internal adoption, we also try to give back and recently open sourced our dependency injection extensions for kotlin-inject github.com/amzn/kotlin-...
