Annotated Android Class Hierarchy

For the life of me, I can't see the "big picture". Every time I think I learned something about Android, a new class pops up in some sample/example code.

True, I can look it up in the (terse) formal reference, but I need something additional: A class hierarchy map, that can remind me of the various relationships between the classes. Something like this.

Ideally, I would be able to print it on paper so that it's always in front of my eyes while learning Android.
