Android: How to check if an application has new inner notifications (ticker)

I don't want to read status bar notifications, I already know how to do that using the following tutorial:

http://www.androiddevelopersolutions.com/2015/05/android-read-status-bar-notification.html

Majority launchers shows a ticker (red circle or number) indicating that an application (As Facebook, Telephone, Messages, etc.) has un-previewed notifications, which is not available in Notifications Panel.

How to accomplish this? How to find that an application (Using it's package name / Activity Name) has an active inner notifications?

Thank you, and please if the question not clear let me know, no need for down vote.
