Android Full-Screen Pop-Up Notification Feature -- 2

I'm in need of a skilled Android Developer to implement a feature that triggers a full-screen pop-up notification on an Android mobile device. The pop-up should activate in response to different types of notifications:

- Message notifications
- Application updates
- Alerts or Warnings

The pop-up should not only display the notification message, but also additional content relevant to each type of notification. For enhanced user engagement action buttons, tailored for each notification type, are required.

Skills and Experience:
- Proficient in Android Development
- Experience with Android Notifications System
- Strong UI/UX skills for intuitive action button design
