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.
