How do you handle dagger scoping using single activity Achi. Let's say I'd like to share a viewmodel amongst my reg fragments. How do I do it without creating another activity?

[tjohnn]

Probably a parent fragment? There has to be a lifecycle owner that both fragments have in common

[sanmi]

A parent fragment is that even possible. I understand that. If I scope it to the main activity. That instance will be retained mostly through out the app.

[tjohnn]

Yes it’s possible, I did use parent fragment scopes for steppers sometimes ago

The "official" suggestion is to use shared viewmodel but as usual with "official" suggestions it has very poor practicality. You might want to consider dagger scopes instead.

Nice! Please can you show me a resource on how to go about it Tosin?

[sanmi]

Ghedoen, I am using dagger scope with single activity at the moment.

[tjohnn]

Not sure of a resource right now.
You would have a parent fragment module and have an @Provides method for the ViewModel created inside the module and you will have the @ContributesAndroidInjector for the child fragments inside it also, from there you can inject the ViewModel inside any of the fragments.

Oh I see, I'm not using dagger-android though.

Thanks, I'll try to apply this principle
