First of all thank you for the nice and correct remark. But actually, I have it running on my emulator and on my HTC Magic without the EGL configuration. Therefore, maybe there are additional reasons.

Nice tutorials…

On this one just a remark: on Android the stencil size is 0 by default, so the shadow is not limited by the floor.
You can see it, if you use white as background color. Then you can define a shadow which overflows the floor.

With the HTC Magic you have to choose a configuration which enables stencil. With your code I had to put the following line in the StencilShadow constructor (before setRenderer( ) method call) :
this.setEGLConfigChooser(5, 6, 5, 0, 16, 4);

PS: with the SDK emulator, none of the EGL configurations are suitable to enable stencil. So no luck for using stencil on the emulator.
