How do i make WhatsApp like full screen incoming call window trigger?

B4X: 
    Service.StopForeground(1)
    'Service.StartForeground(1, Notification1) 
    Notification1.Sound = True
    Notification1.SetInfo("I am WhatsB4", "WhatsB4A", Main)
    Notification1.AutoCancel = True
    Notification1.Notify(1)
    Notification1.Vibrate = True

Applying above code is not triggering UI of incoming call (when phone is locked or alive).



Is there any special option to trigger the incoming call window? On click i need to go to my main activity window just like notification code.

"It is a different activity started with StartActivity."

Maybe some misunderstanding or maybe i am not so transparent in my description.

1 - When i use "StartActivity" its opening my own app in forefront.
Which is not exactly same thing what i am trying.


2 - What exactly i am trying to simulate is the WhatsAPP incoming call UI. which triggers the native incoming call UI of the Device.
How do you trigger that event? and on that native UI on click it opens WhatsAPP.

I hope i am clear about the point 2 here.

You need to have a service that "Listens" to a particular trigger, and show your activity when triggered
