Notification issues

Question

I have developed application which shows Notification on receiving of new update from server.

On arriving of update from server, i can see generated new notification on Device notification area.

A problem which I am facing is that Notification time gets update each time on show.

1. Is there any way to know about already exist Notification of app?
2. I want to regenerate Notification if its not exist

I made R&D but didn't get any method to get existing Notifications which are in device notification area.

Answer 1

To set up a notification so it can be updated, issue it with a notification ID by calling NotificationManager.notify(ID, notification).

To update this notification once you've issued it, update or create a NotificationCompat.Builder object, build a Notification object from it, and issue the Notification with the same ID you used previously.
