Has anyone dealt with "synchronizing" coroutines across Android lifecycle events? For example:

onCreate(...) {
    scope.launch {
        asyncThing()
    }
}

onResume(...) {
    scope.launch {
        // code that depends on asyncThing() having completed
    }
}

Is there a way to "join" such that the onResume work does not start until the asyncThing is done?

You might wanna take a look at CompletableDeferred
https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/-completable-deferred/

Or perhaps just keep the result of the initial scope.launch and join it in onResume

Thanks @kingsley 😄
