title: Play multiple songs with Android intent
body: <p>In my application, I need to launch the Android Music Player. And, for now, it works perfectly : </p>
  
  <pre><code>Intent  intent = new Intent(android.content.Intent.ACTION_VIEW); 
  File    file = new File(file_path);
  
  intent.setDataAndType(Uri.fromFile(file), "audio/*");  
  startActivity(Intent.createChooser(intent, "..."));
  </code></pre>
  
  <p>But the user can't use the "next" and "prev" buttons to switch music. That's why I try to launch multiple songs at once (a playlist). And I don't really know how to do this!
  Give an array to the intent ?</p>
