For Notification : What is the difference between pendingIntent.cancel() and notificationManager.cancel(notification_id)

Question

While doing the notification code, a doubt came in my mind. What is the difference between pendingIntent.cancel() and notificationManager.cancel(notification_id). I mean which one will clear the notification and what will the other one do?.

Answer 1

which one will clear the notification

cancel() on NotificationManager will remove the Notification.

what will the other one do?

It cancels the PendingIntent, so it no longer can be used.
