The official documentation provides a comprehensive guide on the basics of Jetpack Compose, components, layouts, theming, and more advanced topics.

Apparently Jetpack Compose is an Android copy of SwiftUI?

Only two HN threads with comments: https://hn.algolia.com/?q=jetpack+compose

If you want to take a look at code, we have the Jetnews sample app that support different screen sizes. And Jetcaster also implements features such as table top mode.

So I would say that instead if learning everything from Android SDK, you should just set a goal to create some app. Learn about Activities, their lifecycle, layouts (or Compose if you want to be more up to date). Try to implement your app based on this. Then improve your app using Fragments and their lifecycle. If you truly want to understand Views, which are essentially the building blocks of Android UI then I would recommend implementing your own custom View, which will have completely custom look - it is cool thing to try and you will learn how it all works inside.

The compose samples by Google are a good reference to look into: https://github.com/android/compose-samples

Basic understanding of Jetpack Compose.

The compose-samples repo has a comprehensive list of samples ranging from low to complex projects which might be worth a look.

For instance, there is a link to this repository, that contains all sorts of samples, that are up to date and ready to use. That's cutting edge, which is a recommended start.

If you want to open a project in Android Studio, you need its original source code. For instance, go here, then click Code > Download ZIP.

Technically the 2019 version of this repo https://github.com/android/sunflower/tree/5d5dd9e1f0bee1ef506d70aaacf21fe893a9fb83 was significantly less clear than newer versions.

Like looking at Google's android/sunflower app... I see it and it see how they are all divided viewmodel/fragment/workers but what should I be paying attention to when looking at sample apps to learn ?

Lastly, the problem with dig around is, my team is starting a project from scratch so there is nothing to reference. Android at least have some "best practice" example to follow (https://github.com/android/sunflower) Is there something like that for Spring?

After you are quite proficient with the framework, this time you should discover new things. The most trusted source is the samples from Google, for example, Sunflower
