Hi guys, just a quick question. If i pass a variable from the model to view via presenter. Does it violate the rules of MVP? Thanks!

This idea "smells" a bit 🤷

Maybe if you describe the use case people can suggest a better way

View should only get state/data which it can directly show to the user. So when you pass data from model to presenter, you transform that data to either a particular UI state or something that can be directly used by the view to render.

Instead of passing a reference to the View from presenter you could use the Observer pattern to react to changes in the data. We're currently using the latest from Architecture Components (ViewModel + LiveData ) and it works really well!

You can always use rxJava and access Observables in the presenter from View.
