Solution 1:

you need to use a shared viewModel, a ViewModel that is shared between your fragments and survives navigating between certain fragments. Implementation depends on what you use in your project. you can create a ViewModel in the activity and access them from your fragments and put the shared data in this ViewModel. or if you are using navigation component you can have a shared ViewModel per nav graph. and with dagger and koin you can define a costume scope for your ViewModel to survive. see these links:
