Hi when device orientation changes connection between UI and Model being closed.
Did I miss something I’ve not tested orientation changes before

[Arkadii Ivanov]

Hello. I think I will need more details. How do you write the UI? How do you bind the UI and the data?

[rsktash]

I’m using Jetpack Compose ui is bound via Decompose

[Arkadii Ivanov]

Alright. So what is the issue? Is something not working after the orientation change?

[rsktash]

Yes after orientation change ui is not updated and intents are not delivered to Store too

[rsktash]

No forget about what I said before the connection is not lost
What is lost is subscription to event updates from another service
I’ve subscribed to another service in Store.executeAction via scope.launch { flow.collectLatest}
I’m sorry )

[rsktash]

When I comment this block It works properly. Now I’m starting the service in Store.executeAction

[Arkadii Ivanov]

Sorry, it is still not clear to me. I think I will need more code to help with the issue. How is the store created? Does the Action fire after orientation change?

[rsktash]

No Action is fired on Store creation. At the end I moved this code to here

[Arkadii Ivanov]

Is your Store retained?

[rsktash]

Store is not destroyed on configuration changes

So perhaps the issue is because when mediaPlayer#deAttach is called, the subscription Flow inside the Store completes. Your workaround is reasonable. But you should be also able to call attach/deAttach in the place where you actually subscribe. Something like:

scope.launch {
    mediaPlayer.attach()
    mediaPlayer.data.collectLatest(...)
    mediaPlayer.deAttach()
}
