I have a `DialogFragment` that calls a `ViewModel`...

# android

I have a DialogFragment that calls a `ViewModel`'s method, and the method calls a suspending method via viewModelScope.launch. The problem is, when I click OK button on the dialog, I get kotlinx.coroutines.JobCancellationException: Job was cancelled error message and the suspending method doesn't work. How can I overcome this problem? I moved the method to my MainViewModel and accessed it with sharedViewModel, but still the same JobCancellationException occured.

Does the DialogFragment have its own ViewModel? The lifecycle of the coroutine should be tied to the lifecycle of the dialogfragment

[rkeazor]

and make sure your only canceling the job, in ViewModel.onCleared

I get the same exception whether the DialogFragment has its own ViewModel or using MainViewModel as a shared one. And the coroutine is really simple and there's no canceling code explicitly.

fun doSomething() = viewModelScope.launch {
    <http://httpClient.post|httpClient.post><Unit>("<http://example.com>")
}

is viewModelScope from Android KTX?

[rkeazor]

or is that your implementation?

[rkeazor]

also you should move this conversation to #coroutines

OK, thanks.

It's from Android KTX

It was my bad. SharedViewModel works fine.
