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

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
