Android Question Notification Handler

Hi,

In my App when Notification is received, how to handle like other Apps. e.g. In gmail App, when Notification is received and user click/select that Notification, Gmail opens a particular message. In WhatsApp, clicking on Notification opens that message. In our Customer Support App, notification is sent when support ticket is resolved (we sent specific support ticket#), when notification is received user can be on any other part of App, so what approach one should take to show specific support ticket for which Notification is received.

(Notification Listener Lib is included in project)

Thanks a lot,
