How to clear a notification in Android

Question

Is it possible to clear a notification programatically   I tried it with the NotificationManager but its not working  Is there any other way I can do it

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 not end up canceling the Notification, and the notification still appears in the status bar. In this particular case, you will need to issue

stopForeground( true );

from within the service to put it back into background mode and to simultaneously cancel the notifications. Alternately, you can push it into the background without having it cancel the notification and then cancel the notification.

stopForeground( false );
notificationManager.cancel(NOTIFICATION_ID);

Use the following code to cancel a Notification    NotificationManager notificationManager    NotificationManager getSystemService Context NOTIFICATION SERVICE   notificationManager cancel NOTIFICATION ID     In this code there is alway the same id used for notifications  If you have different notifications that need to be canceled you have to save the ids that you used to create the Notification

If you re using NotificationCompat Builder  a part of android support v4  then simply call its object s method setAutoCancel  NotificationCompat Builder builder   new NotificationCompat Builder context   builder setAutoCancel true     Some guys were reporting that setAutoCancel   did not work for them  so you may try this way as well  builder getNotification   flags    Notification FLAG AUTO CANCEL    Note that the method getNotification   has been deprecated

From   http   developer android com guide topics ui notifiers notifications html     To clear the status bar notification when the user selects it from the Notifications window  add the  FLAG AUTO CANCEL  flag to your Notification object  You can also clear it manually with cancel int   passing it the notification ID  or clear all your Notifications with cancelAll      But Donal is right  you can only clear notifications that you created

I believe the most RECENT and UPDATED for AndroidX and backward compatibility  The best way of doing  Kotlin and Java  this should be done as  NotificationManagerCompat from context  cancel NOTIFICATION ID   Or to cancel all notifications is  NotificationManagerCompat from context  cancelAll    Made for AndroidX or Support Libraries
