sound notification when message received from mixpanel
<p>I have integrated mixpanel in my android app code, and I am getting push notifications but I want to hear the default notification sound when the message arrives. 
So I added the following: </p>

<pre><code>    public class notificationReceiver extends BroadcastReceiver {
    @Override
      public void onReceive(Context context, Intent MainActivity) {
         NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
Uri notification =  RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        mBuilder.setSound(notification);
Ringtone r = RingtoneManager.getRingtone(context.getApplicationContext(),    notification);
    r.play();  }
}
</code></pre>

<p>Any reason why this doesn't make sound to the mixpanel notification?
Thank you!</p>
