How to clear a notification in Android
AndroidNotificationsAndroid Problem Overview
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 - Android
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 - Android
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.

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 - Android
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 - Android
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());
}
Solution 6 - Android
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 notification, open corresponding activity and remove notification from notification bar
Solution 7 - Android
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);

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.

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!!!

// Get a notification builder that's compatible with platform versions
// >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this);
builder.setSound(soundUri);
builder.setAutoCancel(true);
this works if you are using a notification builder...
Solution 11 - Android
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager Nmang = (NotificationManager) getApplicationContext()
.getSystemService(ns);
Nmang .cancel(getIntent().getExtras().getInt("notificationID"));

Actually as answered before starting with API Level 18 you can cancel Notifications posted by other apps differet than your own using NotificationListenerService but that approach will no longer work on Lollipop, here is the way to remove notifications covering also Lillipop API.
if (Build.VERSION.SDK_INT < 21) {
cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
else {
cancelNotification(sbn.getKey());
}

All notifications (even other app notifications) can be removed via listening to 'NotificationListenerService' as mentioned in https://stackoverflow.com/questions/17926236/notificationlistenerservice-implementation
In the service you have to call cancelAllNotifications()
.
The service has to be enabled for your application via:
‘Apps & notifications’ -> ‘Special app access’ -> ‘Notifications access’.
Solution 14 - Android
this code worked for me:
public class ExampleReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
int notificationId = 1;
notificationManager.cancel(notificationId);
}
}
Solution 15 - Android
A function written in Kotlin:
/**
* Delete the notification
*/
fun delete(context: Context, notificationId: Int) =
with(NotificationManagerCompat.from(context)) {
cancel(notificationId)
}
Or shorter:
fun delete(context: Context, notificationId: Int) = NotificationManagerCompat.from(context).cancel(notificationId)
Solution 16 - Android
If you use OneSignal, you must use one of this:
Specific notification:
OneSignal.removeNotification(mutableNotification.androidNotificationId)
All notifications:
OneSignal.clearOneSignalNotifications()
In OneSignal's java doc says:
For removeNotification
Cancels a single OneSignal notification based on its Android notification integer ID. Use
* instead of Android's {@link NotificationManager#cancel(int)}, otherwise the notification will be restored
* when your app is restarted.
For clearOneSignalNotifications
If you just use
* {@link NotificationManager#cancelAll()}, OneSignal notifications will be restored when
* your app is restarted.
Solution 17 - Android
To clear notifications on Oreo and greater versions
//Create Notification
Notification.Builder builder = new Notification.Builder(this, NOTIFICATION_CHANNEL_ID)
.setContentTitle(getString(R.string.app_name))
.setAutoCancel(true);
Notification notification = builder.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
createNotificationChannel(builder, notificationManager);
mNotificationManager=notificationManager;
startForeground(1, notification);
//Remove notification
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mNotificationManager.deleteNotificationChannel(NOTIFICATION_CHANNEL_ID);
}
