How to set the frequency of issuance in the Android application?

Question

Android

Hello. I'm writing my first android application, I'm not very good at it yet. I want to make Notifications that would pop up if the user did not enter the application for a certain time (let it be 2 hours). Tell me, which function is responsible for the frequency of notifications?
