In this course, you will use RxJava to build an app using the Model-View-Intent architecture, learning about components like intents, results, and state.

@macsimus
For the “Add Creature screen”. The intention of the user was to “Save” a new creature. So why you created NameIntent, EnduranceIntent, StrengthIntent etc. Only SaveCreatureIntent would have worked right?

Thanks for the question, @sagarsuri. What you suggest is an option. However, by breaking out the intents to one per user-interface element, you’re able to respond to individual user-interface events as they make their way around the MVI flow.

Thanks again!

Hi Joe, I tried to follow the video explanation and apply it on a project but I’m using RxJava3. It might be an ask but please can you have a glance at this github gist and point me in the right direction.

Hi Joe, … I’ve fixed the issue… after 3 days of trying weird things… it turns out problem was autoconnect. I got it to work by changing it to connect… .replay(1)
.apply { connect() }

weird and this is after trying to switch back to rxjava2 (stupid, i know) but all other attempts were futile. At least I know this the fix on rxjava2, I’ll switch back to rxjava3 and try same thing and see.
