How to clear a notification in Android

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?

Solution 1:

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.

Solution 2:

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.

Solution 3:

Since no one has posted a code answer to this:

notification.flags = Notification.FLAG_AUTO_CANCEL;

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

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

Solution 4:

Please try methods provided in NotificationManagerCompat.

To remove all notifications,

NotificationManagerCompat.from(context).cancelAll();

To remove a particular notification,

NotificationManagerCompat.from(context).cancel(notificationId);

Solution 5:

Starting with API level 18 (Jellybean MR2) you can cancel Notifications other than your own via 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());
}
