android beginners group:

Can't run samples. Loaded sdk and eclipse. Everything seems to be running ok. Started new android project for lunar lander sample and then browsed for source in samples. I move down the tree to src/com/ google/android/lunarlander. I then get an error message saying eclipse couldn't find source in folder. I look in the foldr and there is a Java file there. Where is the source for lunarlander?

I also did file>new>project>

Tried everything including reading the the documentation several times. I must be missing something. Nothing works!!

thanks for you help
