simple-stack VS Lottie for Android, iOS, and React Native

As someone who had been using single-activity since 2015 (a'la Flow) and eventually just rewrote the whole thing to fix all the bugs we had with it in 2017, I find it sad that the single-activity approach was questioned not because it was harder, but because people made their own lives harder. And then Google made their lives harder.

I've been using single-activity but with Simple-Stack since 2016 and never deprecated it because Navigation just has these quirks that impede you a lot. I know how to use it but wouldn't really pick it.

This is why we've been using https://github.com/Zhuinden/simple-stack and it was never deprecated. We've been using it for 6 years, I'd say there was a critical bug but it was fixed in 2.3.1...

I mean, we use Simple-Stack because it makes things easier, if it didn't we'd have ditched it long ago https://github.com/Zhuinden/simple-stack

Agreed. I also added support for it 2 weeks ago.

I don't, because we use this and it's better than activities+intents 😅

We've been making single activity apps with https://github.com/Zhuinden/simple-stack and it has been easier than multi-activity.

I still use https://github.com/Zhuinden/simple-stack to this day, although I still use it with fragments.

I have been using Fragments instead of compound viewgroups lately with simple-stack as the navigator for the single-activity, although I need to figure out how to switch to use onBackPressed+onBackInvokedCallback and not just onBackPressed.

You can think of Simple-Stack as a direct successor of Mortar+Flow.

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.

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.

I'd suggest Lottie with a JSON animation file

We was thinking of https://github.com/airbnb/lottie-android

But he did have a commit 3 weeks ago https://github.com/airbnb/lottie-android/commit/7479ebb2847365e5ed0575249a9b639d86808dfa

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.

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.
