title: Notification icon is round white instead of application icon in lollipop
body: <p>I have generated a local notification by this following code.</p>
  
  <pre><code>Notification notification = new Notification.Builder(context)
      .setAutoCancel(true)
      .setContentTitle("title")
      .setContentText("message")
      .setWhen(System.currentTimeMillis())
      .setSmallIcon(getNotificationIcon())
      .build();
  
  
  
  private static int getNotificationIcon() {
      boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT &gt;= android.os.Build.VERSION_CODES.LOLLIPOP);
      return useWhiteIcon ? R.drawable.icon_loli : R.drawable.ic_launcher;
  }
  </code></pre>
  
  <p>where icon icon_loli is 16*16 white icon. still for the api version below 21, it works very fine but on lollipop &amp; above it will show a notification as in image below</p>
