architecture-samples VS MvRx

Here's an example project on GitHub that demonstrates how to use a ViewModel in practice: https://github.com/android/architecture-samples/tree/master/BasicSample

For me this one is the best: Architecture samples it's easy to understand and covers lots of concepts.

Since I never had a mentor or any courses I decided to follow anyone in their development approaches and my choice was google team. There are repo which is supported and update for years, it changes and might slightly differ in branches. But it could answer your questions.

For merging multiple data-sources, like network and database, I can use Repository backed with NetworkDataSources and DbDataSources. For data manipulation, Kotlin's collection has many useful functions (map, reduce, groupBy, count, etc.). If I want to ensure a data can only be emitted once, a simple modification to LiveData is enough (SingleLiveData

Take a look on Android blueprints https://github.com/android/architecture-samples

you might find airbnb/mavericks familiar, because i think it has similar principles & api surface to felangel/cubit

This looks great! Semi-related question... have you evaluated other MVI frameworks like Mavericks / Uniflow / Orbit? What made you decide on Mobius?

Everything in MVI is just more code that does nothing (see how most MVI frameworks are basically just a wrapper over state.value = state.copy() like in Orbit or MvRx which you wouldn't even need if you used combiners) and instead adds unnecessary constraints over MVVM that don't help you at all. The "sealed class inputs" are basically a reinvention of calling interface functions except you create classes for it, despite there being no asynchronicity when you have a View -> ViewModel communication.

Airbnb doesn't use MVI, we use MVVM via https://github.com/airbnb/mavericks

Check out the latest dagger sample from the repo. Dagger recently added assisted injection into the core library so you can now integrate the two without adding assisted inject!
