title: android play music on opening app
body: <p>I want to make an app for my mom's birthday which is tomorrow that displays a happy birthday message(already got that taken care of) and plays the happy birthday song when the app is opened. I'm a complete noob to android programming and don't know anything more than basic xml but I want to get this done. Can you guys please show me how what code to use to play a song on opening the app without any more input from the user?</p>
