Fragment Lifecycle implementing Navigation Component in Android 14 - ViewModel implementation patterns Properly
I'm working through a tutorial and I'm experiencing an scenario with the Android Navigation Component in conjunction with ViewModels in Android 14... I have a Fragment that is supposed to initialize a ViewModel in its `onViewCreated` method, but it seems that the ViewModel is not being initialized properly under certain navigation conditions. Here's a snippet of my code: ```kotlin class MyFragment : Fragment() { private lateinit var viewModel: MyViewModel override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) viewModel = ViewModelProvider(this).get(MyViewModel::class.java) viewModel.someLiveData.observe(viewLifecycleOwner, Observer { data -> // Update UI with data }) } } ``` The question occurs when I navigate back to this Fragment after navigating away. Occasionally, the `someLiveData` does not emit any updates, and the UI stays blank even though I expect it to have data. I've confirmed that the ViewModel is not being re-initialized; it looks like it retains the old instance but isn't receiving updates when I navigate back. I've tried using different lifecycle scopes and even `ViewModelProvider(requireActivity())` to see if it makes a difference, but the question continues. I also checked that the LiveData is being updated correctly in the ViewModel, as it works perfectly when I first navigate to the Fragment. Has anyone encountered this behavior, or does anyone know what might be causing this? I've also made sure that my Fragment is not being recreated unnecessarily during navigation. Any insights on how to resolve this scenario would be greatly appreciated. Any help would be greatly appreciated!
