is it possible to easily inject a viewmodel into a Service?

In trying to inject this via by viewModel() per the docs, I wind up with the following:
java.lang.ClassCastException: com.myapp.MyService cannot be cast to androidx.lifecycle.ViewModelStoreOwner

Doing by viewModel() inside of Activity and ComponentActivivty works fine. I also tried switching from Service to LifecycleService with no luck. Any help is appreciated! 🙂

🤔 Try adding the interface KoinComponent to your Service.

this was my backup plan (or just doing a bit of refactoring to rely on a different class), just found it odd that the docs say it should be just this simple 🤔

We use that with a Service and can use

by inject()

without any problems. Don't think you will be able to use viewModel 🤔 As your Service isn't a View, right? So why you would need that? If any logic you want is inside that ViewModel, I would say to extract into a UseCase and inject in your ViewModel and in your Service.

yeah, I agree from a "semantic" standpoint, I was just approaching it from the standpoint that a ViewModel as an architecture component doesnt really formally have anything to do with UI that I know of, but is nicely tied to the lifecycle of its owner

with this in mine I figured that if google went to the trouble to build LifecycleService it'd be worth a shot

also my particular broader requirements annoyingly require methods specific to activities so I've been having to think of creative solutions 😛 - something to revisit on monday I suppose 😄
