I had the same wrong class problem with the compatibility library and tried everything mentioned above with no luck. I finally figured it out: I was using the incorrect XML element Fragment rather than correct one fragment . Capitalization seems to matter.
I just solved this problem in Android API 8 machine (Samsung Galaxy S).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
