The CrossFade effect uses Pixel Bender, which is not supported for AIR mobile applications.

The CrossFade effect performs a bitmap transition effect by running a crossfade between the first and second bitmaps. The crossfade blends the two bitmaps over the duration of the animation.

At any point in the animation, where the elapsed and eased fraction of the animation is f and the pixel values in the first and second bitmaps are v1 and v2, the resulting pixel value v for any pixel in the image is:

v = v1 * (1 - f) + v2 * f

The bitmap effect is run by a pixel-shader program that is loaded by the effect. You can specify a different crossfade behavior by specifying a pixel-shader program to the shaderByteCode property. That pixel-shader program must meet the requirements defined in the AnimateTransitionShader effect.
