you all say that this is impossible.
This is because it is not possible, with the exception of the manufacturer of the home screen or application widget (instead of the launch icon).
if so, how to do this, these 2 applications and other applications can do it?
Because Samsung wrote the home screen and can do what he wants on his home screen.
Do I need to make as few icon images and exchange them or something else?
This will not work, since you cannot change the startup icon at runtime.
is this really possible and why?
You can really do this by creating an application widget or by creating your own home screen.
