Android Programming for Beginners

By: John Horton

Overview of this book

Modern Android development has evolved rapidly, with Kotlin and Jetpack Compose becoming the standard tools for building powerful mobile applications. Android Programming for Beginners provides a practical introduction for readers with little or no coding experience. Rather than overwhelming you with theory, the book teaches concepts gradually through hands-on experimentation and small, focused apps that reinforce core programming fundamentals. You will begin by learning Kotlin essentials including variables, loops, functions, lambdas, collections, and object-oriented programming before moving into Android Studio and Jetpack Compose. As your skills grow, you will create interactive projects ranging from UI layouts and games to multimedia and database-driven applications. Along the way, you will explore Android development techniques such as state management, navigation, Material Design, Room databases, Canvas drawing, and responsive layouts. To help future-proof your workflow, each chapter also includes optional AI-assisted programming exercises that show how modern coding tools can support experimentation, accelerate development, and deepen understanding. By the end of the book, you will have built a portfolio of Android apps and gained the confidence to continue toward advanced mobile development projects independently.

Summary

We have made a fast start! We know we are using Android Studio and Kotlin because they are the best tools for the job by a mile. We have also installed Android Studio, created an app, and previewed it in the Design view tab. We also launched an AVD (device emulator) and ran our simple app as if it were on a real device.

We looked at the project structure and the Project window modes and concluded that we don't need to go into depth at this stage. We have also taken a glance at our first Kotlin code. Most of it is still alien to us, but we will be digging deep into Kotlin throughout the rest of the book.

We also looked at AI and concluded that it is a personal preference whether to integrate it into your coding life.

In the next chapter, we will build 3 more apps, look at the code, learn how to output text for debugging, learn about the Android lifecycle, see some much-needed interactivity in an app, and play with a cool folding screen device emulator.
