Do you have any sample code/project that using coroutines in the android custom view? I would like to learn the best practice that handle coroutines in custom view.

there are no best practices in coroutines in custom views:P coroutines should not live in the viewlevel. If you really have to, i guess you could cancel the scope in onViewDetached, maybe

My strategy is to avoid if possible and keep the view dumb.... network calls live in the VM since they have to survive config changes anyway and the view is only interested in the result in certain scenarios it might make sense to expose suspend functions from the View and launch the coroutines from the lifecycle owner if 1 and 2 don't work then I might consider creating a scope and what ☝️ suggested

New version of lifecycle library allows you access lifecycle scope of view' (Activity or Fragment), search for findViewTreeLifecycleOwner

findViewTreeLifecycleOwner

is a useful func to me. Thank you. ---- I want to replace handler in custom view, e.g. auto delay scroll in custom ViewPager2. is it a good practices using coroutines in custom view in this case?

yeah, I don’t see any issues with this use case to use coroutines
