Arduino and Android: LED Notification Reminder

Hello All! I am currently constructing a personal desk lamp, using my Arduino, a led ring light and Ionic to create an app for it. I have gotten successful connection between the Arduino and phone using Bluetooth. now I want to implement a notification checker into the app.

The app will intercept incoming push notifications, and feeds the information through a Bluetooth connection over to an Arduino in the form of a alert.

I have looked up a few ways of doing this. I don't want to create Push Notifications for my own app, neither do I want to do local notifications if neither is needed. What android library would give me a good start with this?

I am looking to create something in the sense of a timed, 10 second alarm that would trigger a function in the Arduino to blink a LED for 10 seconds.
