Individual Incoming Call Screen

Question

I am trying to add a few views to the incoming call screen with the required functionality. Is it possible to override the exis android OS call screen? Is there a way to achieve this as a standalone application.?

Thanks in advance.

Answer 1

I think that the activity of an incoming call has a high priority, which is installed by Linux at the kernel level. You must set a high priority to display your screen, then the activity of the incoming call will be in the background. it uses the concept of an intent and intent filter.
