Android

This course covers various aspects of building Android applications, focusing on creating robust and efficient apps. The course is divided into several modules, accompanied by quizzes and coding challenges that will test your understanding of the course.

You’ll start with an overview, which introduces the Android platform and its key features. Then, you will learn the various Android layouts and UI components—how to create and use different layouts, fragments, and custom views. Moreover, you’ll practically learn about activity and lifecycle management, and how to handle images and work with RecyclerViews.

Next, the course covers Android UI components such as bottom navigation bars, alert dialogs, and web views. You’ll learn about intents, notifications, threading, services, app permissions, user location, and Firebase services—including authentication, real-time databases, storage, and cloud messaging.

By the end of the course, you will be able to create functional and well-performing Android applications.

# Introduction

A `Fragment` is a reusable portion of an activity. It typically defines a part of the user interface intended to be used across activities.
> Fragments must be used as a part of Android activities and can’t be used independently.

Similar to a `View`, a `Fragment` binds a layout to a class, but unlike a `View`, it provides us with an abstraction of several lifecycle methods. A `Fragment` can contain views, events, and logics to manage the interaction of views and events.

## Importance of fragments
- A `Fragment` allows us to reuse the binding of a `View` and its behavior based on the events it supports across activities.
- It allows device-specific support (phone or tablet) or orientation (landscape or portrait) UIs to reuse shared elements while being open to differences.
- In an application that follows the fragment-based architecture, activities serve merely as navigation controllers while fragments are responsible for rendering views and the relevant logic.

# Creating a fragment
Let’s discuss the steps to create and use a fragment in our `ExampleActivity`.

## Environment setup

Add the following dependency in the `app/build.gradle` file to use the AndroidX `Fragment` class. 

```
implementation("androidx.fragment:fragment-ktx:1.4.0")
```

Make sure that Google’s Maven repository is configured for our app. 

Learn about fragments and their lifecycle functions with end-to-end examples.
