I am using AppCenter to send notifications for my Xamarin.Forms application. AppCenter is sending these notifications through Firebase-Cloud-Messaging service to Android devices. I need to handle incoming notifications without the user clicking the notification.
To handle incoming notifications when the app is in the background or killed, the notification payload should contain the data payload. But with AppCenter you can't send messages with 'data' payload (https://github.com/microsoft/appcenter/issues/87).
Now I'm looking for a way to handle notifications with a custom-service or something similar. In this SO question (https://stackoverflow.com/a/47312925/5278005), someone has already mentioned that they already implemented it.
@annihil we ended up having to create our own implementation of a BroadcastReceiver and JobIntentService to receive the FCM messages and explicitly pulling out the intent filters which sent the messages to the FCM classes shipped w/ their SDK – Jake Hall Jan 30 '18 at 11:58
How can we handle incoming notifications containing the notification payload when the app is in background/killed?
