When it comes to <https://github.com/android/nowinandroid|the Now in Android sample app> , why is it good/ok that <https://github.com/android/nowinandroid/blob/main/app/src/main/java/com/google/samples/apps/nowinandroid/ui/NiaAppState.kt|NiaAppState> is not a ViewModel? We have `MainActivity` -&gt; `NiaApp` -&gt; `NiaAppState` -&gt; `UserNewsResourceRepository` and in all of this there's no ViewModel involved. As soon as we move to using Compose, how do we decide when a ViewModel is and isn't necessary?

see the comment just above yours. Not everything needs to be in a viewmodel, depending on your needs it's perfectly fine to store this in a state holder, as in the case of this example in the Nia app

Take a look at this talk from Manuel Vivo <https://www.droidcon.com/2022/08/01/implementing-modern-android-architecture/|https://www.droidcon.com/2022/08/01/implementing-modern-android-architecture/>

There's also a section in the official doc.
