Share ViewModel between fragments that are in different Activity

Question

I have a ViewModel named SharedViewModel:

public class SharedViewModel extends ViewModel {

    private final MutableLiveData selected = ne         


        

Answer 1

Well, I created a library for this purpose named Vita, You can share ViewModels between activities and even fragments with different host activity:

val myViewModel = vita.with(VitaOwner.Multiple(this)).getViewModel()

The created ViewModel in this way stay alive until its last LifeCycleOwner is destroyed.

Also you can create ViewModels with application scope:

val myViewModel = vita.with(VitaOwner.None).getViewModel()

And this type of ViewModel will be cleared when user closes app

Give it a try and kindly let me know your feedback: https://github.com/FarshadTahmasbi/Vita
