I have a case where I'm using

BehaviorRelays

with viewModel, the problem is in case of the device rotation,

ViewModel

subscribe again which cause duplicate subscription with each rotation. I know I could save a subscription with

Disposable

and dispose it if it exists, then subscribe .. but is there any other cleaner solution.

AutoDispose https://github.com/uber/AutoDispose

you should not subscribe again on rotation, thats the whole point of viewmodel retaining

@ursus yes but how you observe ui, the whole ui is recreate with the life cycle, you must to bind subscriptions again.

sideffect to behavior relays,and expose them to the ui

that's when you need to update UI, but how to Observe user interactions, like clicks, updating texts

oh yea sorry, I use regular functions like viewModel.userClick()
