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.

I've also tried several gradle plugins as you suggest (from the simple gradle jar, to a custom fatjar, to the badass plugin) and everything works properly while I'm on Manjaro Linux with OpenJDK-11. The problem though is that if I try to distribute the application to Windows, says to the friends of mine, they are still using JRE8 while I'm targeting JVM11...
