I've searched through net and got a final that the event alarm can be cancelled and the particular event alone can be updated with new time for alarm. I'm struck out here how to implement it.

You don't want to be messing with the calendar. It's not part of the Android API, and even if there exists a back door, it is highly discuraged to use it.

Even if you want a "Snooze" functionality, you won't be able to capture the Intent that causes the alarm to go off, as this is not an API standard, and may be fired targeting a specific receiver class.

You can however access and modify the calendar entries through the Google Data API, but that's a whole different story.
