I've looked at your code and I see a couple of things that are
questionable.  First, your activity.info looks like this:

name = hMouse
service_name = org.teleton.ingenieria.hMouse
class = hMouse.hMouse
icon = activity-hMouse
activity_version = 1
license = GPLv3+
show_launcher = yes

Instead of class = you might try this:

exec = sugar-activity hMouse.hMouse

Second, you have these statements:

sys.path.insert(0, "lib/")
sys.path.insert(0, "/home/olpc/Activities/hMouse.activity/")
sys.path.insert(0, "/home/olpc/Activities/hMouse.activity/lib/")

These should not be necessary.  Everything in your Activity should be
either part of the normal Python path or contained in the XO bundle.
You're also hard coding paths that may not always exist.  If I test
your Activity using sugar-emulator, for instance, I won't have those

Another questionable thing is this in Procesador.py:

img = pygame.image.load("/home/olpc/Activities/hMouse.activity/help/camara.png")

The path to the image should be relative to the XO bundle location,
not an absolute path.  Check out my "Demoiselle" activity here:


It looks like your Activity interacts with the hardware in unusual
ways.  This may not be allowed by Rainbow, which is a kind of sandbox
used by Sugar.
