This document outlines the curriculum for an Android development course using Android Studio, covering topics like Kotlin programming, app design, user input, navigation, and data handling. Participants will learn to create apps including a birthday card, dice roller, and tip calculator, while understanding collections and activity lifecycles. The course includes badges for achievements and requires basic computer skills and access to a computer with internet and optionally an Android device.

Concept Overview

० A collection is a group of related items, like a list of words, or a set of
employee records.
० he collection can have the items ordered or unordered, and the items can be
unique or not.Kotlin provides numerous functions for adding or deleting
items, viewing, and manipulating collections.
० A collection usually contains a number of objects (this number may also be
zero) of the same type. Objects in a collection are called elements or items

० Another type of collection in Kotlin is a set.
० It's a group of related items, but unlike a list, there can't be any duplicates,
and the order doesn't matter.
० An item can be in the set or not, but if it's in the set, there is only one copy
of it. This is similar to the mathematical concept of a set.

० The last type of collection you'll learn about is a map or dictionary. A map is
a set of key-value pairs, designed to make it easy to look up a value given a
particular key.
० Keys are unique, and each key maps to exactly one value, but the values can
have duplicates.
० Values in a map can be strings, numbers, or objects—even another
collection like a list or a set.

० As a user navigates through, out of, and back to your app, the Activity
instances in your app transition through different states in their lifecycle.
० The Activity class provides a number of callbacks that allow the activity to
know that a state has changed.
० The system is creating, stopping, or resuming an activity, or destroying the
process in which the activity resides.
Activities and Stages of Activity Lifecycle

18. This work is licensed under the Apache 2.0 License
० Within the lifecycle callback methods, you can declare how your activity
behaves when the user leaves and re-enters the activity.
० If you're building a streaming video player, you might pause the video and
terminate the network connection when the user switches to another app.
० These can be buttons, lists, edittexts etc. The activity however has its own
lifecycle and you can listen to the events emitted by the activity through
lifecycle methods.
