Difficulty with LiveData implementation guide in Fragment when observing from ViewModel using DataBinding in Android 14
I'm trying to configure I'm maintaining legacy code that I'm deploying to production and After trying multiple solutions online, I still can't figure this out..... I'm working with an scenario where my LiveData in the ViewModel is not triggering UI updates in the Fragment when using DataBinding. I have a ViewModel that exposes a MutableLiveData property, but even after updating the value, the UI does not reflect these changes. Here's a snippet of what I have: ```kotlin class MyViewModel : ViewModel() { private val _data = MutableLiveData<String>() val data: LiveData<String> get() = _data fun updateData(newValue: String) { _data.value = newValue } } ``` And in my Fragment, I'm setting up the binding like this: ```kotlin class MyFragment : Fragment() { private lateinit var binding: FragmentMyBinding private lateinit var viewModel: MyViewModel override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { binding = DataBindingUtil.inflate(inflater, R.layout.fragment_my, container, false) viewModel = ViewModelProvider(this).get(MyViewModel::class.java) binding.lifecycleOwner = this binding.viewModel = viewModel return binding.root } } ``` I ensured that `lifecycleOwner` is set correctly, but the UI does not update when I call `viewModel.updateData("New Value")`. The observer seems not to be triggered because I'm not seeing any logs from `onChanged` method which I set up earlier. I also checked if the binding was correctly initialized and there are no exceptions in the logcat. I've tried adding an explicit observer in the Fragment: ```kotlin viewModel.data.observe(viewLifecycleOwner, { value -> Log.d("MyFragment", "Data changed: $value") }) ``` However, this also fails to log when I update the data. I suspect it might be related to the Data Binding setup or some lifecycle scenario, but I need to pinpoint the exact cause. Any suggestions on what might be going wrong or what I could check next? Any suggestions would be helpful.
