Apps Why don't notifications show up when I run the app?

I'm a beginner programmer and I've been working on an app that shows events and notifies the user when a new event is up.I'm trying to create a settings activity with 2 switch buttons, 1 for notifications on status bar and 1 for notification sound. When I turn on the switches, I don't get any notification nor sound.
How can I fix that?
