Adding Preloader to mobile app

I can’t seem to get the preloader to work on the mobile app. Some advise on this please

Ok so it seems I still have need for this. Is this possible?

What exactly are you having difficulties with. I use it and it works just fine in an app. Just add it the same way you would for a web app?

Ok so I finally figured it out after all this time. Its the z-index: in the CSS. I had to set it very high. Wow!!! I wasted a couple years.

.dmxPreloader { z-index: 9999; }
