[Question] Using ViewModels in Service

Hi,

Everything is great with ViewModel. They work as expected in the Activity and Fragment. Recently I have encountered an need to use the ViewModel in Service. I’m not sure how exactly to do that.

I found one answer on StackOverFlow: https://stackoverflow.com/questions/44708202/observe-livedata-from-foreground-service But I want to know what’s the best practice to use ViewModel in Service.

The ViewModel should be used closely with an Activity or a Fragment, so it’s destined to live in the UI layer of your application. Therefore, I don’t recommend using the ViewModel in a Service. Create a different class, that would be used in the Service and, if needed, in the ViewModel. Like this you ensure the separation of concerns and avoid giving the ViewModel more responsibilities than needed.
