In case you are using NotificationCompat.Builder , you can use :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
mBuilder.setOngoing(true); //this will make ongoing notification

NotificationManager mNotifyMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); mNotifyMgr.cancel(mNotificationID); – Ashraf Alshahawy Sep 22 '17 at 08:02

Assign Notification.FLAG_ONGOING_EVENT flag to your Notification.

Sample code:

yourNotification.flags = Notification.FLAG_ONGOING_EVENT;
// Notify...

If you aren't familiar with the Notification API, read Creating Status Bar Notifications on Android developers website.

Also you should start ongoing notifications with `Service.startForeground` NOT using `NotificationManager.notify()` – Blundell Mar 20 '12 at 08:55

Shouldn't that be `|=`, not `=`? – Ky - Jul 25 '14 at 02:13

It is actually recommended to bitwise-or notification flags, rather than set the flags directly. This allows you to set multiple flags at once.

For example:

notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;

will set both flags at once, whereas:

notification.flags = Notification.FLAG_ONGOING_EVENT;
notification.flags = Notification.FLAG_SHOW_LIGHTS;

will only set the FLAG_SHOW_LIGHTS flag.

public static final int FLAG_ONGOING_EVENT

Since: API Level 1
Bit to be bitwise-ored into the flags field that should be set if this notification is in reference to something that is ongoing, like a phone call.

public static final int FLAG_FOREGROUND_SERVICE

Since: API Level 5 Bit to be bitwise-ored into the flags field that should be set if this notification represents a currently running service.
