how can i show custom dialog box (when call comes true caller shows caller id like that) when my android application receives notification

问题

popup message like whats app, caller id like the true caller, I am trying to make the same thing.

I tried using a broadcast receiver but I do not know how to show the dialog box when a broadcast receives a notification.

a pop-up message like WhatsApp shows when a notification arrives on a phone.

Set mainactivity as a launcher screen. In the mainactivity before setContentView method calling check if the intent has extra parameters as per your requirement. If yes, then finish the current activity and start DialogActivity.
