This is quite simple  You have to call cancel or cancelAll on your NotificationManager  The parameter of the cancel method is the ID of the notification that should be canceled   See the API  http   developer android com reference android app NotificationManager html cancel int

this will help   NotificationManager mNotificationManager    NotificationManager              getSystemService NOTIFICATION SERVICE   mNotificationManager cancelAll      this should remove all notifications made by the app  and if you create a notification by calling  startForeground      inside a Service you may have to call   stopForeground false     first then cancel the notification

NotificationManager cancel id  is the correct answer  Yet you can remove in Android Oreo and later notifications by deleting the whole notification channel  This should delete all messages in the deleted channel   Here is the example from the Android documentation   NotificationManager mNotificationManager            NotificationManager  getSystemService Context NOTIFICATION SERVICE      The id of the channel  String id    my channel 01   mNotificationManager deleteNotificationChannel id

If you are generating Notification from a Service that is started in the foreground using  startForeground NOTIFICATION ID  notificationBuilder build       Then issuing  notificationManager cancel NOTIFICATION ID     does t work canceling the Notification  amp  notification still appears in the status bar  In this particular case  you will solve these by 2 ways   1  Using stopForeground  false   inside service   stopForeground  false    notificationManager cancel NOTIFICATION ID     2  Destroy that service class with calling activity    Intent i   new Intent context  Service class   i addFlags Intent FLAG ACTIVITY NEW TASK   i addFlags Intent FLAG ACTIVITY CLEAR TASK   if ServiceCallingActivity activity    null        ServiceCallingActivity activity finish      context stopService i     Second way prefer in music player notification more because thay way not only notification remove but remove player also

You can also call cancelAll on the notification manager  so you don t even have to worry about the notification ids   NotificationManager notifManager   NotificationManager  context getSystemService Context NOTIFICATION SERVICE   notifManager cancelAll      EDIT   I was downvoted so maybe I should specify that this will only remove the notification from your application
