I want to acheive following thing:
Suppose an end user presses the default green colour button to initiate a call. At this moment, my application must handle that request and do some processing. That means the application is trying to override the phone's default application (essentially written by the phone manufacturer itself) to handle call requests.
Is this at all possible? Please feel free to clarify me, because i'm quite new in this domain.
Thanks in advance.
