I followed the official guide to set up a long-running worker with WorkManager (Kotlin version). Now I need to update the notification with the operation progress. The documentation says:
// Calls setForegroundInfo() periodically when it needs to update // the ongoing Notification
However I can't find any setForegroundInfo() method. So how do you update the ongoing notification?
It's a typo in the documentation. A Kotlin app should call the CoroutineWorker method setForeground(), a suspending function that makes the CoroutineWorker run in the context of a foreground service. Example:
setForeground(createForegroundInfo(myProgress))
The documentation contains another error: The ForegroundInfo constructor has two arguments, not one. So the code:
return ForegroundInfo(notification)
should be
return ForegroundInfo(notificationId, notification)
where notificationId is an integer that uniquely identifies the notification.
You could find detailed information in Google CodeLabs with examples. There are 2 courses you can take:
I can't find any setForegroundInfo() method
Same to me, looks like the document is misleading the reader.
So how do you update the ongoing notification?
Simply use the NotificationManagerCompat.notify() method, that's it.
