How to create a Notification in the Action center when the app is in the suspended state...?

Question

Hi,
I want to send a notification to the action center of Windows phone 8.1, when I get a callback from the lower layer code which I have registered for(I have implemented). I am able to do it when my app is in the foreground. How can I achieve the same when
the app is in the background.(ie. in the suspended state)

Yes Franklin, your understanding is correct. But I cannot use Push Notification, as it require a cloud server to send the raw notification.
Is there any other method, which can be used to trigger the app (ie... the background service registered) to send a toast message, when app is in background. Trigger should be initiated by a lower layer service running as different process. I am looking
for something similar to "Broadcast Receiver" in Android... 
Hi Jose,

The Background Task is the only way to make things work in the background in Windows phone, it have some triggers we can use, such as
SystemTrigger,
TimeTrigger, or
NetworkOperatorNotificationTrigger:

I would also recommend you to read this sample:
