So far you might got used on having a single ViewModel instance per Fragment? So when you regularly instantiate one ViewModel in your Fragment, it's often scoped to a lifecycle of your Fragment, right? And by scoping that one ViewModel to a single Fragment you cannot share values between multiple Fragments. Which make sense.

In order to Share values from the same ViewModel instance between
multiple Fragments, you need to scope ViewModel to an Activity instead. Watch the video to learn more about it.

I just want to tell you that you saved me from further stress today. Been having a problem with a parent fragment and its child fragment that are supposed to share one viewmodel. The key was "activityViewModels". Thanks for explaining what it's for!

Man!!! I was running crazy after this! You explained well you showed an example well! you just earned a sub <3

[mwahajsajidali]

Thanks man, I am learning android development, and I am working on a project which uses the concepts of navigation. I wanted to retrieve data from 1st Fragment. I tried everything like I tried data Classes to save data from 1st Fragment and use it in the 2nd Fragment but it did'nt work. Then, I realized that there must be another way of communication between two Fragments. Thank You very much for this information.

[kamandemwangi]

Thank you man. I was having trouble navigating between fragments as my viewmodel was scoped to fragments instead of the activity.

Can you please do a video on how we could save the recycler view scroll positions used in fragments using the shared shared ViewModel... As of now I m hiding and showing fragments while navigating which is not an elegant solution
