I've few questions on Android Framework. Can someone please answer them

i) What does an Android Framework do? What is it's job?

ii) What are these managers - Activity Manager, Location Manager etc? Are they APIs or libraries?

iii) I heard that the definition of a framework is - a set of libraries that say “Don’t call us, we’ll call you.” So can I say that Activity Manager, Location Manager etc are such libraries? Or is it that they are not libraries but APIs (used to access underlying c/c++ libraries) and the actual libraries that do "Don't call us, we'll call you." are hidden from us?
