OpenPlug|Studio ships with its own SDK and though it seem like FlexSDK dependent, there are native components to work with for mobile devices. The major or the most used native component is List and one can access it as

mob:List id="allSDCardFiles" 
	x="0" y="0"
	height="100%" width="100%"
	rowHeight="45"

While it is expected to work fine and it does work fine in the simulator, but when tested on device (I have used an Android phone to test), the application simply crashed. Well the problem here is a bug in the baseSDK of OpenPlug. So till the bug is fixed the simple solution is to use a default itemRenderer. The fixed code will look as

mob:List id="allSDCardFiles" 
	x="0" y="0"
	height="100%" width="100%"
	rowHeight="45"
        itemRenderer="ListItemRenderer"
	

That simply works every where from simulator to the device.
Hope that helps someone out there.
