Animotion – a visual CSS animation app
Worth mentioning that After Effects can export CSS/SVG/canvas animations with the free bodymovin/Lottie plugin. This is my personal go to for creating web key frame animations and elements.
Not every after effects feature is exportable, but it’s the best and most reliable solution I’ve found for this type of workflow, maybe due in part though to my previous experience with AE.

Develop Animated Splash Screens on Fire TV with Lottie
A smooth and visually appealing on-boarding experience can greatly impact how users perceive the quality of your app. In my previous article, we explored how to create custom splash screens on Fire TV apps to optimize the startup time and improve user experience. Building on that knowledge we will take a step further and learn how to develop an animated splash screen using Lottie for Fire TV applications.

Ask HN: Are there things that Flash did that we still can’t do with today’s web?
Lottie[1], an Adobe After Effects plugin, fills a gap in vector animation authoring and is quite widely used (primarily in mobile applications but also works on the web, Discord for example supports them for stickers).
It's a pity SVG animation authoring tools never eventuated since it's an underutilized native format.

Oldhead here - what has replaced Flash for highly interactive, complex animated content?
Unity can export to WebGL/WASM, so that's one option if you're making some kind of heavy interactive experience and you don't mind waiting for it to load. For just animations there are tools like Lottie that can help. I think things are generally a lot more fragmented than they were in the Flash/Shockwave days though.

Skottie Now Available for SkiaSharp
Uno Platform contributed support for the Skottie component in SkiaSharp (a .NET binding for Skia). This addition now allows for any application using SkiaSharp to render Lottie animations and provide engaging user experiences on all the platforms already supported by Uno Platform. This new SkiaSharp preview update also provides support for Uno Platform WinUI targets as well as .NET 6 for Mobile

I'm Matthew, a software engineer at Duolingo, here to answer… any questions you'd like to send my way. AMA!
We use Lottie to render our animations! I believe the animators use After Effects to create them. Thanks for the love! I'll pass them to our animators :)

Lottie – use After Effects animations in web and native apps
They should add the Flutter package for it on the "third party platform" page! :) (https://airbnb.io/lottie/#/other-platforms)

Is this similar RxJava, the reactive extensions library for https://github.com/ReactiveX/RxJava ? I have made that work in Clojure in production.

How to do threading in Android.
Since you mentioned java, there is RxJava and RxAndroid. Google general recommendation now is to use kotlin coroutines if you're considering writing your app with that.

You all beat me to MapStruct and Testcontainers. Honorable mention to RxJava, which I use in Desktop apps.

What are the most common used (3rd party) libraries and frameworks used in Android development?
Concurrency: Kotlin coroutines for general use, Rx or Flow for reactive programming (you can technically use Rx for regular concurrency as well, but not really what it's meant for)

When consuming from a reactive stream is it more like a literal stream where items in the stream ay go by and not get consumed while you're busy, or is it more like a queue?
In big words, kafka and rxJava are 2 different things, with kafka you transport data, produce and consume messages, then you can process them however you want. Rx java helps you write asynchronous code and it's no queue/topic related. You can read more here
