If you look at my book example on using PyGame you'll see that I
recommend copying the sugargame directory into the root directory of
the Activity:


You are also doing this.  That's why your import for sugargame is
working, not because you're adding anything to the Python path.  You
might try the same thing with your version of pygame.  I don't know if
that will fix anything, but it's worth trying.  Have a look at my
simple pygame example too, and see how it differs from yours.
