Prevent user from dismissing notification

Question

Some apps have notifications which can´t be dismissed by swiping them away.

How can I manage such behaviour?

Answer 1

In addition to Andro Selvas answer:

If you are using the NotificationCompat.Builder, just use

builder.setOngoing(true);

Answer 2

I used the below code to make my notification persistent:

startForeground(yourNotificationId,notificationObject);

To make it dismissable, just do the below:

stopForeground(true);

Answer 3

Use the flag,FLAG_ONGOING_EVENT to make it persistent.

Notification notification = new Notification(icon, tickerText, when);
    notification.flags = Notification.FLAG_ONGOING_EVENT;

Also you can check, FLAG_NO_CLEAR
