How do I make an alert screen with sound similar to the native alarm clock app?

Hello, I have an automation project and I created an android app to receive the esp data and do the data processing, however in a certain situation the user needs to be alerted urgently, so I want to make a warning screen with sound and that touch with the mobile even in the silencer, would be an alert screen similar to the screen that the android's native alarm clock has. I do not know where to start, if someone can give me strength I will be very grateful.
