Kotlin Coroutine Scope Issues When Using ViewModel in Android 14
I'm working with a question with coroutines and the ViewModel scope in my Android application. I have a ViewModel that initiates a background task using `viewModelScope.launch`, but when I try to update the UI with the results, I'm working with a `JobCancellationException`. Here’s a simplified version of what I’m doing: ```kotlin class MyViewModel : ViewModel() { fun fetchData() { viewModelScope.launch { val data = fetchDataFromNetwork() // This is a suspend function // Updating LiveData myLiveData.value = data } } } ``` When I call `fetchData()` from my Activity, it seems to work fine at first, but when I navigate away from the Activity and return, I get this behavior: ``` Exception in thread "main" kotlinx.coroutines.JobCancellationException: JobCancellationException in a failed child of CoroutineScope( CoroutineName(myViewModel)) ``` I've ensured that my network call using Retrofit is properly set up, and that `fetchDataFromNetwork()` is a suspend function. I suspect that the coroutine is being canceled when the Activity is destroyed and then recreated, but I want to understand how to handle this scenario correctly. I’ve also tried using `viewModelScope.coroutineContext[Job]?.invokeOnCompletion` to log when the job is completed, but I don’t see any useful information. I’ve read about using `LiveData` to observe changes in the UI, but is there a better way to ensure my coroutine continues to work properly even when the Activity is recreated? Any suggestions on what I can do to fix this scenario? This is happening in both development and production on Linux. Any suggestions would be helpful.
