How to remove notification from notification bar programmatically in android?

Question

Anybody have idea how can we remove notification from application programmatically which is called using Pending intent.

I have used to cancel notification using following method.

AlarmManager am=(AlarmManager)getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(Display.this, TwoAlarmService.class); PendingIntent pi = PendingIntent.getBroadcast(Display.this, AlarmNumber, intent, PendingIntent.FLAG_CANCEL_CURRENT); am.cancel(pi); 

But problem is notification which fired already that are not removed from notification bar.

Thanks in advance...

Answer 1

Maybe try this :

NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.cancel(NOTIFICATION_ID); 

OR, you can also do this to cancel all notifications in given context:

notificationManager.cancelAll(); 

See this link to the documentation : NotificationManager

Answer 2

I believe the most RECENT and UPDATED 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.
