show that a layer is loading and rendering?

[linusang]

I would like to show a progress bar or some processing animation to show a layer is loading and rendering it's graphics. Loading a GeoRSSlayer, most of the time it will take 2-4 seconds to show the graphics... and within the 2 - 4 seconds.. the app becomes unresponsive... is there a way to overcome this?

Have you looked at the progress bar sample on our SDK?
