Flows or Channels? In today's 9-minute video, we'll see why channels can model certain kinds of workflows well, even when the Flow API isn't a natural fit. www.youtube.com/watch?v=qyMP... #Kotlin #AndroidDev
When Flows Won't Cut It

Callback-based libraries crampin' your style? With just a super-thin adapter layer, you can convert that third-party callback-based library to work beautifully with Kotlin's coroutines. Here's how. www.youtube.com/watch?v=Ii3w... #Kotlin #AndroidDev
Say Goodbye to Callbacks

We've been looking forward to this one! Kotlin 2.4 introduces collection literals. Create lists as easy as `val x = [1, 2, 3]`. They can even be combined with name-based destructuring for a neat effect. Today's 6-minute video is all about 'em: www.youtube.com/watch?v=cXg4... #Kotlin #AndroidDev

It's always fun to bring back a souvenir for your family when you travel. Ninja loves her new Kodee plushie from KotlinConf! (And don't worry - she's taking very good care of it.)
You asked for it, you got it! This week's video covers Hot Flows, including SharedFlow and StateFlow. In less than 15 minutes, we'll cover the most important things you need to know about them. www.youtube.com/watch?v=u3bz... #Kotlin #AndroidDev

Kotlin's return value checker - lots of developers missed this one. In this video, I show how you can use it to expect call sites to use the values returned from your functions. See you at KotlinConf this week! www.youtube.com/watch?v=VDEQ... #Kotlin #AndroidDev
Gotta use that returned value?

Kotlin Flows can throw exceptions... So how should you handle them? Does a regular try-catch work? In today's video, I show where you should (and shouldn't) use try-catch, and what you need to know about the `catch` operator. Watch the video here 👉 typea.li/as/yt2610

In Kotlin's Flow API, when the emitter and collector run on different coroutines, how can we handle values that the collector can't keep up with? In today's 8-minute video, we'll see how we can use buffers, conflation, and debouncing for different effects. www.youtube.com/watch?v=rHYl...

Have you tried name-based destructuring in Kotlin 2.3.20? In this clip from the recent TypeAlias Show, you can learn all about the three modes of this new experimental feature, and see how you can start using it (or migrating toward it!) in your own projects. www.youtube.com/watch?v=tvpB...

Kotlin's flows really become fun once we start putting our emitters and collectors on separate coroutines... but we can't just call `emit()` from inside a `launch` block, because of Context Preservation! In this week's video, we'll see what Context Preservation is and why it's... (1/2)
Livestream this week! We'll look at updates in the #Kotlin and #AndroidDev worlds, like: - Kotlin 2.3.20 - AS Panda 2 - Android Bench - Updates on sideloading - and more! Google Calendar: typea.li/as/cwnvzvk Download Invite: typea.li/as/3gvy7yb Livestream Page: typea.li/as/live10 See you there!
Yes, #Kotlin flows have a lot of familiar operators from the collection and sequence APIs, but since they run on top of coroutines, they also have many operators that you won't find in those APIs. In today's video, I show off some operators that you'll only find on flows! youtu.be/SfS4KOfjc4E

This #Kotlin update was easy to miss! You can now use `return` in expression bodies. On the surface, it sounds useless, but I put together this 6-minute video to show the reasons why it's actually an important update. www.youtube.com/watch?v=Y8hu... #AndroidDev

Concurrency + Mutable State = Risk Kotlin's design of coroutines prevents a lot of problems, but not race conditions. It does give us some great tools to help, though! Here's a 9-minute video that covers what you need to know about each one. I hope you find it helpful! 👉 youtu.be/Ap-cVIM5ORY
