Are there any use cases for using Channels in Android Development, or are you exclusively using Flows in your apps?

We're using channels for one time events, as a replacement for SingleLiveEvent

@luke_c Hmm, but Google says we shouldn't use channels for one time events: https://medium.com/androiddevelopers/viewmodel-one-off-event-antipatterns-16a1da869b95

In practice it's very unlikely it's going to be a problem... But I agree with the principal of handling events as state like the article mentions

Okay, and as far as I understood, events can only stay unprocessed if

send()

and/or

collect()

are called on a different Dispatcher than

Dispatchers.Main.immediate

, which shouldn't be the case that often since

lifecycleScope

and

viewModelScope

use this dispatcher by default, right?

Yes that's my understanding. It's important you use a buffered Channel so any events sent when there are no subscribers are buffered and not dropped

Okay, by default they have a capacity of 0, so we have to set it to a value >0, correct?

We use Channel.BUFFERED One caveat is that Channels have a fan out behaviour, so it's not reliable if you need multiple observers, but that's generally not a problem for most people and the same limitation that SingleLiveEvent has
