title: How to play sound in whole Android Application background
body: <p>Hello stackoverflow's members !!</p>
  
  <p>I have terrible problem, I don't know how to implement service to play sound in background in my whole application.</p>
  
  <p>I followed this <a href="http://www.codeproject.com/Articles/258176/Adding-Background-Music-to-Android-App" rel="nofollow">tutorial</a> but it seems to be not working for me.</p>
  
  <p>Have you guys any idea how to do that?</p>
