Thank you, Mark, that's very helpful. Having written a textbook (on assembly language), I know first-hand how difficult it is to make these things clear. "Writing is God's way of showing us how unclear our thinking is."

I am just starting to learn Android programming (but have 50 years of
programming experience).

In the developer.android.com/guide/topics/fundamentals.html I see "The
Android operating system is a multi-user Linux system in which each
application is a different user." So this says that an application is a
user.

Further down, under Application Components, Activities, I see "An activity
represents a single screen with a user interface." Has the Dev Guide now
switched to a human user?

As I continue through the Dev Guide, how do I determine when it is referring
to a human user versus a software (application) user?
