implementing Kotlin Coroutines and ViewModel Lifecycle on Android 14 when Fetching Remote Data
This might be a silly question, but I'm dealing with Does anyone know how to I'm relatively new to this, so bear with me. I'm experiencing a question when using Kotlin Coroutines inside a ViewModel to fetch remote data from an API on Android 14. The data fetch works fine when the app is in the foreground, but when I navigate away from the activity and back, the data is not being refreshed as expected. I'm using Retrofit for the network calls and LiveData to observe the data in the UI. Here’s a snippet of my ViewModel: ```kotlin class MyViewModel(private val repository: MyRepository) : ViewModel() { private val _data = MutableLiveData<DataType>() val data: LiveData<DataType> get() = _data fun fetchData() { viewModelScope.launch { try { val response = repository.getDataFromApi() _data.postValue(response) } catch (e: Exception) { Log.e("MyViewModel", "behavior fetching data: ${e.message}") } } } } ``` And my repository method looks like this: ```kotlin suspend fun getDataFromApi(): DataType { return apiService.getData() // Retrofit call } ``` I call `fetchData()` in my activity’s `onStart()` method but it doesn't seem to refresh the data if the user navigates away from the activity and then returns. Instead, it retains the old data from LiveData. I also tried adding `observeForever` on the LiveData to force updates, but that led to memory leaks. Additionally, I’m seeing this warning in the logcat when I navigate back: `Warning: want to perform this action after onSaveInstanceState`. Any ideas on how to ensure the data is refreshed correctly whenever the user returns to the activity? Should I consider a different approach for data fetching in relation to the ViewModel lifecycle? This is part of a larger web app I'm building. Any ideas what could be causing this? Any feedback is welcome! My team is using Kotlin for this application. This is happening in both development and production on CentOS. Is there a simpler solution I'm overlooking? Any ideas how to fix this?
