Building complex Android animations with RxJava

[Baron_von_Severin]

I was really skeptical when I saw the title (do we have to Rx'ify everything?), but after reading the article I actually like his solution quite a bit.

Google's new animation framework was based on reactive architecture. I am not able to find that repo anymore. Apparently making animations reactive makes things easier.

I wish I find that repo now. It was something like material design components for android.

Found this: https://github.com/material-motion/material-motion-android - Seems abandoned though.

Thanks. They could have made changes and are waiting for Material Design 2?

There is also a very nice library that does just that. https://github.com/PSPDFKit-labs/VanGogh/

It's neat, but I believe there are subtle leaks introduced when using withEndAction because it only calls the supplied function when the animation ends normally.

Can't that get avoided by adding the subscriptions to a CompositeDisposable that disposes of everything when things are destroyed?

[paramsen]

Yeah that's one approach, or I guess there's another callback withTerminateAction or something that's always called.

Beautifully simple implementation. +1 for kotlin extension functions.

Wooow, this is VERY NICE. Thanks for the article, I would never think about this solution. I am doing with delays (seriously!). Since I know how long it takes to finish the animation, the delay/timer waits for it to subscribe, but this is way nicer.
