Unexpected Behavior with Fragment Lifecycle During Configuration Changes in Android 14
I'm attempting to set up I'm having a hard time understanding I'm encountering a strange issue with fragment lifecycle events when my app undergoes configuration changes, specifically on Android 14. I have a fragment that fetches data from a ViewModel in the `onCreateView` method. However, after a configuration change (like rotating the device), the `onCreateView` is called multiple times, and sometimes the data retrieved from the ViewModel is inconsistent. Here's the relevant code snippet from my fragment: ```kotlin class MyFragment : Fragment() { private lateinit var viewModel: MyViewModel override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { viewModel = ViewModelProvider(this).get(MyViewModel::class.java) viewModel.data.observe(viewLifecycleOwner) { data -> // Update UI with data } return inflater.inflate(R.layout.fragment_my, container, false) } } ``` I expect that the data should be fetched only once, but after rotating the device, the UI updates multiple times with overlapping data. I tried using `viewLifecycleOwner` to observe the LiveData, but it seems like the fragment’s lifecycle methods are being called in a way that I didn’t anticipate. I also verified that the ViewModel is scoped correctly to the fragment, so it shouldn't be re-created on rotation. In my ViewModel, the data is fetched using Retrofit and stored in a MutableLiveData. The Retrofit request works well, but I suspect that the lifecycle methods may not be managed correctly after the configuration change happens. I tried using the `setRetainInstance(true)` method in my fragment, but it doesn't seem to have any effect. Additionally, I’ve ensured that I’m not manually instantiating the ViewModel elsewhere in the code. Is there a best practice I might be missing here regarding the handling of configuration changes with Fragments and ViewModels, or could there be an issue with the way I'm observing the LiveData? Any insights would be greatly appreciated! I've been using Kotlin for about a year now. I'm using Kotlin LTS in this project. Any help would be greatly appreciated!
