Hey, is there a way to know when object is no longer available so subscriptions, coroutine scope, etc, can be cancelled? Like with

ActivityScoped

, when activity is destroyed - in this particular case I could've get an activity with

ActivityContext

and listen to the lifecycle, but this won't work generally, e.g. with

ActivityRetainedScoped

. The only idea that come to my mind is using

finalize

but it seems to be a bad practice and doesn't seems to be reliable - as I understand there's no guarantee it'll be called on time. Usually

Closeable

is used in such situations, I've tried implementing it but Dagger doesn't seems to be checking it.

you can use

ActivityRetainedLifecycle

which has

onCleared

callback

@FunkyMuse cool, that's what I was looking for! and there's no analog for

ActivityContext

- I need to cast context to activity and listen the lifecycle, right?

that’s how i’d do it, sadly there’s no analog, you can maybe open a FR on Github

@FunkyMuse and what's about non scoped objects? their lifecycle depends on the caller object lifecycle

You don't have to scope an object if it's parent is scoped, that instance (child in this case) will be scoped as well (inherit) it's parent's lifecycle, the child may have dependencies too and they'll inherit from it etc... So yes it depends on the caller (unless a listener with initialize/clear which you'd know to handle yourself)
