Android : How To Get Caller Name Which Displays On Incoming Call Screen?

Suppose my application xyz stores a few contacts(just like in the address book/ telephone book). Other contacts are by-default stored in my Android address book. Suppose I receive a call on the handset with my app xyz running in the background. All I need is to fetch the Caller's name from the application xyz and display this name as" Akash Calling..." instead of "+91... calling..." assuming that caller's details are present in the application say, his name and none of his details in the actual address book. Is this feasible.
