in order for an application to play a tune, you need something that knows how to work with an audio file. So in this assignment, you'll be working with Android's MediaPlayer and possible the AudioManager. To do so, make sure to import the following: android.media.MediaPlayer android.media.AudioManager and don't forget your ClickListener... 1. The example apk and wireframe only have a STOP button, swap this out with a STOP, PAUSE & PLAY button. 2. Incorporate a progress bar into the application 3. Incorporate screen rotation 4. The music should stop playing once the application is closed.
