I am interested in this feature as well for Master/Detail.

Another use case is that if you have a full page spinner activity that loads data from the network.
Once the data is loaded the app navigates to a 2nd activity that presents the data.

We would like to be able to use the same ViewModel instance in both activities.

Adding a situation which I need this: I don't want the UI to wait for a network call. Showing a detail activity will need to get the detail data from the server.

So if I start the API call (which is of course done by the ViewModel) as soon as the user clicks the item, it is already fetching the data while transitioning to the second screen.
Then I don't have to block the starting of the detail activity or wait to trigger the API call until the detail activity is started

@ #4

My solution for share data between multi activities:

https://github.com/googlesamples/android-architecture-components/issues/29#issuecomment-407291032

what is the status of this issue ??

does any work has done regrading this ??

we need fatures share the viewModel between activites to apply ViewModel with old project without restructure the app from zero

Please add this feature, unfortunately this request has been ignored for 3 years

Isn't it just good enough to create a singleton of the viewmodel? I do this using Koin

Can't believe there is one piece of AD on #10 Floor....

 "My only possible issue with that approach is -> The ViewModel is expected to be cleared when onCleared() is called. Will onCleared() be called multiple times (answer: yes)? For example, if Activity A and B share a ViewModel and from Activity A, I start up Activity B, then close Activity B, onCleared() be called while Activity A still needs the ViewModel. I really feel this version of ViewModels wasn't designed to actually be used across multiple activities."
