That being said; a framework is a library, whose most
important service is provided by calling methods
(?callbacks?) of its client via an interface
(inversion of control).
In a trivial sense, every programming language has one
framework, that which calls the client's ?main? method.
An operating system is a framework for application programs.
So, we use the term ?framework?, when there is more than a
single trivial callback for the whole program.
For example, on Android there are several ?life-cycle
callbacks? for an activity, and the standard library of
Android thus is a kind of framework.
The framework is similar to the ?Context? of the Strategy
Pattern, with the client providing concrete strategies,
or to the abstract class in the Template Method pattern.
