# coroutines

[Jan]

kind of android related, but which coroutine scope would you use in background services? e.g. intent services or job services?

[Evan R.]

As long as it’s not reading files or anything I’d use Dispatchers.Default

[Jan]

that's the context but how would you launch them?

[streetsofboston]

val scope = CoroutineScope(Dispatcthers.Default + SuperVisorJob())

scope.launch { .... }

[Jan]

thanks 🙂

CoroutineWorker with WorkManager

[Adam Powell]

just creating a new scope like the above doesn't include when to cancel it for cleanup or otherwise manage lifecycle along with Android; CoroutineWorker does this for you

[Adam Powell]

and WorkManager is a lot more compatible and robust across Android versions than working with IntentService or JobService directly

[Saket Poddar]

Agreed with @Adam Powell with above implementation you will have to manage your coroutineScope to cancel. Better use WorkManager where you can return results as well.

Just beware of unique work, for some reason it could get stuck... if you return failed for sure, but even if not, sometimes I have some works that stay blocked and just don't run until all works get purged.

[dave08]

Whereas IntentService just queued them, and keeps running them even if previous ones fail.
