workflow-kotlin VS compose-samples

For example square has open sourced workflow https://github.com/square/workflow-kotlin (MVI + plugin based architecture), if you look other examples like molecule they use Presenters (not the MVP ones) which is completly different. The only common thing is that they are both UDF.

workflow. Quite a shift in how you write an app, but enough extension points that it's not that much of an issue, and it's really pleasant to use.

I don't know how common/popular it actually is, but it's definitely not uncommon. Square has been doing this kind of home-made navigation for quite a while as far as I know (most recently in the form of workflow-kotlin), Lyft (Scoop) as well, and more (e.g. Conductor).

We'll focus on Jetpack Navigation here, however most of the content applies for any navigation library or tap action. In fact, I first implemented this at Square on top of Flow and Workflow.

There's kotlin workflow by square https://github.com/square/workflow-kotlin

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.
