Play the Media Sound! (Background music)

Can you Imagine a life without music? Please don't imagine 😊

This tutorial is all about implementing background music in your apps and especially games.

Keep the music.mp3 file in main->res->raw folder.

The guitar or any image you wish should be kept in the drawable folder.

I downloaded the image from Pixabay.
