Android Toolkit @ Google

[Ian Lake @ianhlake]

My team at Google is hiring in London! We're looking for mid-level Android developers who want to work in the 'UI Architecture' layer of Jetpack i.e., Paging, Fragments, Lifecycle, Activity, Navigation and SavedState as we focus on Jetpack Compose and KMP

#KotlinConf videos are live !

It was an absolute pleasure getting a chance to speak this year and give some insights into how we're approaching Kotlin Multiplatform in Jetpack.

AndroidX + KMP 🥰

First KMP developer previews are now publicly available!

There is still a ton of work ahead of us, but this has been a long time in the works, and I'm so excited to finally be able to share this.

[Android Developers @AndroidDev]

🔦 An experimental preview of Jetpack libraries for @kotlin multiplatform is now available to explore.

Try these builds of Collections and DataStore now, and let us know what you think of them! 📚

Read on about these experimental dev builds ↓ https://t.co/uyusGo7l63

[Dustin Lam @itsdustinlam]

FYI if you've been having jumping issues in paging-compose try Compose 1.3.0-alpha03.

A fix for this in LazyList / LazyGrid was released last week!

Ever confused about what's happening in Paging's internals?

Paging 3.2.0-alpha02 is out now with some debug logging and a fix for some missing version constraints!

https://t.co/RG6lopssaw

[Dustin Lam @itsdustinlam]

Kotlin-ification of androidx.collections is underway, and we've hit our first milestone with the 1.3.0-alpha01 release today!

Please give it a shot and let us know if you hit any problems. We've already caught some bugs internally thanks to Kotlin 😮

https://t.co/5oGNNI78z1

[Dustin Lam @itsdustinlam]

Paging 3.2.0-alpha01 is released with the ability to set CoroutineContext instead of just CoroutineDispatcher.

We also have some nice bug fixes (including for compose), so please check it out!

[Rahul Ravikumar @tikurahul]

Make sure you are using baseline profiles when using Compose. It makes a huge difference !

[Rahul Ravikumar @tikurahul]

Jetpack Macrobenchmarks 1.1.0-beta06 is out. This is our last beta. (https://t.co/VdBvHYn6vt)

If you are benchmarking Baseline Profiles, you will have to use the ToT version of androidx.profileinstaller for better cold start measurements. (https://t.co/wEeOkYLmf0)

[droidcon San Francisco @droidconSF]

Rahul Ravikumar will officially be speaking at #dcsf22! Don't miss @tikurahul's talk on how to make #apps blazing fast with #BaselineProfiles at #dcsf22 📢 Read more about it here: https://t.co/zpFqHmwjKW

The Android Studio team is hiring to help on a new project to make Studio usable for Android OS development: https://t.co/jKHLK83KOk

[Dustin Lam @itsdustinlam]

Paging 3.1.1 released today with a small fix to remove redundant LoadState.NotLoading events which were injected between retry / invalidate / refresh after calling .cachedIn.

@kevincodes_ Check out the testing guide on DAC: https://t.co/2QLEjkWzdF

In general, you want test components in isolation. For integration tests, make sure to fast-forward / await any work, then realize the state in a presenter such as AsyncPagingDataDiffer so you can inspect the state.

[Dustin Lam @itsdustinlam]

@LucianTepes Are you passing the keys argument into items(LazyPagingItems) ? They keys mapping provides a stable id for compose for handling scroll position restoration. It's a bit hard to guess the issue without seeing the code, but the other common problem for this is not calling .cachedIn

[Dustin Lam @itsdustinlam]

...and now my bed hair is forever enshrined in the archives of the internet, but at least we answered a lot of Paging questions!
