title: Notification sound in android
body: <p>In my android application, I want to notify the user with a sound without showing the notification. Is that possible ?  </p>
  
  <pre><code>Notification n = new Notification();
                  n.icon = com.android.mms.R.drawable.wap_message;
                  n.defaults |= Notification.DEFAULT_SOUND;
                  n.flags = Notification.FLAG_AUTO_CANCEL;
  </code></pre>
  
  <p>This is the code I am using to show the notification, So I commented icon and flags of the notification as follows</p>
  
  <pre><code>Notification n = new Notification();
                  //n.icon = com.android.mms.R.drawable.wap_message;
                  n.defaults |= Notification.DEFAULT_SOUND;
                  //n.flags = Notification.FLAG_AUTO_CANCEL;
  </code></pre>
  
  <p>But it is not working.</p>
