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.

Ranges & When

As the title suggests, in this chapter, we will learn about ranges (a concept) and when, a keyword. A range in Kotlin is exactly what it sounds like; a range of values with a starting value and an ending value, but much more interesting, and what we will explore in this chapter is what we can do with ranges and the associated keywords.

A when-based expression in Kotlin is a neat replacement for if-else blocks, allowing you to match a value against multiple conditions in a concise, readable way. The when keyword is yet another part of Kotlin's expressiveness, enabling us to write clearer, less error-prone code, often in less time. Furthermore, as with ranges, there are a bunch of associated keywords we can use in conjunction with when that give us more refined control over the execution of our apps.

In addition, we will learn more Jetpack layout tricks by introducing LazyColumn, along with ranges and when in 2 demo apps.

In this chapter, we will:
