How do I clear all notifications with separate app?

Question

Is it possible to make an icon on android that when clicked clears all notifications, e.g. SMS, email, missed calls etc? I just want an icon on my home screen that clears all notifications. What coding would I use?

Answer 1

You can only remove a Notification that you raise yourself. You cannot remove a Notification raised by another application.

Answer 2

cancel(notificationID) where you pass the notification id of the notification you have created

or else, you can clear all your notifications by cancelAll().

*NOTE : * Only notifications created by your application can be deleted. You cannot remove notifications created by some other application.
