I am currently working on text chat application built with Xamarin Forms, i have a requirement to display a full screen page once a chat is initiated, a whatsapp incoming call notification is an analogy here. I do have push notifications setup, so i do receive a push notification once a chat is initiated but I can't find a way to display a full screen custom page with controls to accepting/rejecting a chat. This page needs to appear in foreground mode/background mode or when the phone is locked. Any lead would be helpful. At the moment I am really keen to solve this for android.
Thanks in advance.
