Hi, daniel

I've also had that during my various, tries. But this is probably not
the source for the problem, as another Exception is thrown...
Can someone explain the meaning of InflateException as I'm not a
native speaker, i do not really understand it.
I think of a balloon that is blown to big...  o_O
