You can use:
UUID.randomUUID()

Check the documentation for UUID class at the android developers documentation

thanks for the reply pascal. if i need to set the more than one notification, i need to set the unique id of that.
notificationManager.notify(1, notification);

while doing this i was thinking about the unique id. since i am new in android, i am interested to know about the unique id generation.

ok i understand.
Whats the Problem with it.
You have a interger i and every time when you Display a notification you do i+=1;
Then at runtime you have an unique id in every norification
