Next big thing is coming! It looks like time to start playing with this.

Romain is the best speaker @Google , he doesn't hesitate to even talk about Google's/their inefficiency or mistakes and he is also humorous… We want more lectures and videos from him…

Seems that good old Java for Android will gone in a next couple of years.

The question is which one would they prefer more Kotlin or Dart?

Hey this was the flutter style of building UI. This was one the cool feature of flutter..but flutter has many more cool features like this.but Thanking you Team

I don't get. It looks like all those teams inside Google are fighting against each other. PWA, Flutter, now Jetpack Compose… Why do they invest so much time to invent so many instruments for different languages just for 1 OS. Just make 1!
I'm trying to step up my android game, what should i learn? I was going for flutter, but now we have similar declaritive UI in Android and i'm hell confused. Like most of the newcomers.

This is very interested point from Google IO 2019

Seems for me like an attempt to solve a problem that have never existed. Build an ui from code? A very fresh idea! How to preview it? How to build constraint layout from code and doesn't use 1k lines? Should we just build and see like flutter says (with wasting a few minutes)? Thanks, but no thanks

Every time he says "so it turns into something very simple" I get goosebumps ;).. Yeah android and "simple" :))
Hakki San说道：

2020年2月22日上午7:16

Again any thing made to solve their problems and not to make it better ?
Ken Yee说道：

How you use Styles with this? Styles were useful for things like white labeling and different device size support..

28:50 people haven't been doing it like this?

As someone who left Android development mid 2015, this has tempted me to come back as it looks a lot easier to write and manage the UI.
Since 2015 have basically only used web apps, since most stuff needed to be cross-platform.
Frank Sullivan说道：

2020年2月22日上午7:16

Wait, are those literals in dips? e.g. 4.dp @21:41
Giorgos Kylafas说道：

2020年2月22日上午7:16

24:47 Finally, code is data (is code)! This will open up a new world of easily programmable UI. The apps of the future are going to be very interesting…

Great to see they actually credited Litho, Flutter etc

12:30"(…) if you have pets, small children, or and open plan office" Ahahah!
Gulshanur Rahman说道：

Please make this Android-first, but cross-platform.
Tomasz Rykała说道：

I love the Spinner backstory.
Abhi Singh说道：

2020年2月22日上午7:16

all the pain through the years.. no more!
martin seal说道：

This basically is flutter, I hate it, I love flutter but they shouldn't be bleeding into each other
Alex Alexandrov说道：

2020年2月22日上午7:16

This is like Flutter =)
kojadinm说道：

2020年2月22日上午7:16

Thomas Gallinari说道：

2020年2月22日上午7:16

This is truly awesome, very much like Flutter but for native Android with Kotlin! Can't wait for a stable version!

Federico Jimbo Smithson说道：

2020年2月22日上午7:16

but kotlin is still just java bytecode that uses JVM like runtime
Adrian Tache说道：

2020年2月22日上午7:16

This looks a lot like React Components and I think I like it!
