Does Android have Task == Application?

Question

The terms “task” and “application” are part of the new Android terminology I'm learning. In the Actions and Tasks section of the Dev Guide, the following attention caught my attention:

The user presses the HOME key, goes to the application launches and selects a new application (in fact, a new task) .

What caused the question: “Task” - a synonym for “applications” in the Android world?

If not, what are the differences between the two?

Answer 1

Task

A task is a sequence of actions that a user performs to achieve a goal, regardless of which applications the actions relate to.

Application

A program that performs actions.
