How to clear notification in Android

Question

Can I clear a notification programmatically?

I tried it with NotificationManager but did not work. Is there any other way I can do this?

Answer 1

Use the following code to cancel the notification:

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

This code always uses the same identifier used for notifications. If you have different notifications that need to be canceled, you need to save the identifiers that you used to create the Notification.

Answer 2

From: http://developer.android.com/guide/topics/ui/notifiers/notifications.html

To clear the notification about the status line when the user selects it from the Notifications window, add the flag "FLAG_AUTO_CANCEL" to the "Notification" object. You can also clear it manually using cancel (int) by passing it a notification identifier or clear all your notifications using cancelAll ().

But Donald is right, you can only clear the notifications that you created.

Answer 3

Since none of them sent a response to this code:

 notification.flags = Notification.FLAG_AUTO_CANCEL; 

.. and if you already have flags, you can OR FLAG_AUTO_CANCEL:

 notification.flags = Notification.FLAG_INSISTENT | Notification.FLAG_AUTO_CANCEL;

Starting at API level 18 (Jellybean MR2), you can cancel notifications other than yours through NotificationListenerService.

 @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2) public class MyNotificationListenerService extends NotificationListenerService {...} 

...

 private void clearNotificationExample(StatusBarNotification sbn) { myNotificationListenerService.cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId()); } 

Answer 5

Try the default method specified in NotificationManager .

NotificationManager.cancelAll() to delete all notifications. NotificationManager.cancel(notificationId) to delete a specific notification.

Answer 6

If you are using NotificationCompat.Builder (part of android.support.v4 ), just call its setAutoCancel object setAutoCancel

 NotificationCompat.Builder builder = new NotificationCompat.Builder(context); builder.setAutoCancel(true); 

Some guys report that setAutoCancel() does not work for them, so you can also try this method

 builder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL; 

Please note that the getNotification() method is deprecated !!!

Answer 7

  String ns = Context.NOTIFICATION_SERVICE; NotificationManager Nmang = (NotificationManager) getApplicationContext() .getSystemService(ns); Nmang .cancel(getIntent().getExtras().getInt("notificationID"));

In fact, as said before starting with API level 18, you can cancel notifications published by other applications than your own using NotificationListenerService, but this approach will no longer work on Lollipop, here is a way to remove notifications that also cover Lillipop API .

 if (Build.VERSION.SDK_INT < 21) { cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId()); } else { cancelNotification(sbn.getKey()); }

If you generate a notification from a service running in the foreground using

 startForeground(NOTIFICATION_ID, notificationBuilder.build()); 

Then issuing

 notificationManager.cancel(NOTIFICATION_ID); 

does not cancel the Notification, and the notification still appears in the status bar. In this particular case, you will need to release

 stopForeground( true ); 

from the service to return it to the background while canceling notifications. Alternatively, you can push it into the background without canceling the notification and then canceling the notification.

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

Answer 10

  Notification mNotification = new Notification.Builder(this) .setContentTitle("A message from: " + fromUser) .setContentText(msg) .setAutoCancel(true) .setSmallIcon(R.drawable.app_icon) .setContentIntent(pIntent) .build(); 

.setAutoCancel (true)

when you click on a notification, open the corresponding activity and delete the notification from the notification panel

Answer 11

  // Get a notification builder that compatible with platform versions // >= 4 NotificationCompat.Builder builder = new NotificationCompat.Builder( this); builder.setSound(soundUri); builder.setAutoCancel(true); 

this works if you use the notification builder ...
