Hi! What would you use to communicate between in Android example ViewModel and CoroutineWorker(WorkManager). Point is that in viewmodel I can't create worker and vise versa, so they can't communicate directly. Here ViewModel is producing hls chunks (ts files) and worker would upload them when new is created. I can make one object Repo which would connect both pieces but I don't know what to use inside, Channels, Flow? In worker I have one suspend function which need to be blocked while not everything is uploaded. Would be glad if someone could help me with that ☺️ Thanks!

I’ve never actually used work manager, but from what I understand you’ll want to persist it to a db. Your app and an instance of work manager are two separate processes so communicating between them can’t be done easily with normal constructs like a flow or channel.

Wow, nice, that's a great idea with database. Sometimes it's a must to think out of the box :) Thanks

The run in the same process, unless you use the work-multiprocess artifact. Since they are in the same process, you can have some in memory repo also that communicates with a channel. But i agree the dB makes it easy.

As far as I know, using official APIs you can only communicate status and a final result. https://developer.android.com/guide/background/persistent/how-to/manage-work#:~:text=At%20any%20point%20after%20enqueuing,a%20tag%20associated%20with%20it.&text=The%20query%20returns%20a%20ListenableFuture,success(outputData)%20.
