Android 2.2 Music Track Project

Hi All, I am working on a basic application which I would like to add sound to in the form of a sound effect and sound tracks. To give a quick breakdown on what I am looking for: Three screens: A Splash Screen (which can just display the words 'Splash Screen'), Main Screen and Action Screen Sound Effect to be played when Splash Screen appears Main Theme Track to play when menu screen appears On/Off button on main and action screens to be able to toggle sound on and off. I have provided the button image for this. The image will change depending on if the sound is on or off. Button on the main screen which when clicked will take the user to a simple activity that will play one of 2 random tracks (this screen also has a back button which will return the user to the main screen). All tracks should fade out if possible. I have attached a screen by screen description, sound files and button image files. The music files are .ogg files and the sound effect is a .wav file Thanks for taking a look at my project. Cam
