Kotlin Coroutines Not Resuming on Main Thread in Android 14 with Retrofit
I'm learning this framework and I'm working on an Android 14 project using Kotlin Coroutines and Retrofit, and I've encountered a frustrating scenario where my coroutines aren't resuming on the main thread after making network calls. The request is successfully executed, but the callback to update the UI doesn't seem to work as expected. I'm using `viewModelScope` to launch my coroutines. Here's a code snippet of what I've implemented: ```kotlin class MyViewModel : ViewModel() { private val _data = MutableLiveData<List<Item>>() val data: LiveData<List<Item>> = _data fun fetchData() { viewModelScope.launch { val response = repository.getItems() if (response.isSuccessful) { _data.postValue(response.body()) } else { Log.e("MyViewModel", "behavior: ${response.errorBody()}") } } } } ``` In my repository, I have the following code: ```kotlin suspend fun getItems(): Response<List<Item>> { return apiService.getItems() } ``` And in my Activity, I'm observing the LiveData: ```kotlin myViewModel.data.observe(this) { items -> // Update UI with items itemsRecyclerView.adapter = ItemsAdapter(items) } ``` I'm not seeing any updates in the UI after I call `fetchData()`. I've verified that the network request is successful by checking the logs, but it appears that the `_data.postValue()` call is not reaching the observer. I've also tried switching to `launch(Dispatchers.Main)` within the coroutine, but that didn't change anything. The app does not crash, and there are no behavior messages in the log that indicate what might be wrong. Does anyone have insights into why the UI isn't updating in this scenario? Could it be related to the threading model or how LiveData is being observed? Any help would be greatly appreciated! Could someone point me to the right documentation? I'm coming from a different tech stack and learning Kotlin. Any examples would be super helpful. This is my first time working with Kotlin latest. What am I doing wrong?
