Answer 1

You have to write a broad cast receiver for incoming calls the Pratiks answer have the tutorial for that.Then simply make a pop up window over the default screen. you can call the pop up class from the broadcast receiver. hope you got it:)

Answer 2

You cannot modify default screen but instead of this you can launch your screen for that you need to use BroadCastReceiver for incoming calls
