Flex Hero, how to make a whiteboard for Mobile Flex App in Android platform?

[HamlinXu]

I had made a whiteboard with the sdk 3.5 for PC, but when i use the same way in the SDK Hero, i can't draw any shape.

I use a image to draw picture on it, and the   image.source   is   a  Sprite, and when i creat a new shape,  i add it in the Sprite,

it is worked in the sdk 3.5, but it is not work in the Mobile Flex App.

can anyone help me?

Thanks  HamlinXu
