App Design Apprentice

Learn Modern App Design with Figma!

This book guides you through designing modern mobile apps using fundamental design principles.

This book is for intermediate iOS and Android developers who already know the basics of mobile app development but want to also learn how to design apps with attractive and effective UI and UX.

Topics Covered in App Design Apprentice Figma: Learn the basics of this modern design tool. App Teardowns: Analyze and pick out the best parts of other well-designed apps. Wireframes: Explore what makes good app user flows. Reusable Components: Learn to create and use reusable components such as buttons and toolbars. Typography: Basics for communicating hierarchy, order and emphasis. Color: Leverage visual styles and palettes. Transitions and Animations: Create different transitions between screens to communicate relationships. Design Systems: Implement best practices for creating good app experiences in each ecosystem.

This book will leave you with the knowledge needed to design modern mobile apps that are functional and attractive.

Advanced Git

Master Git!

Chances are if you’re involved with software development you’ve heard of and have used Git at some point in your life. Version control systems are critical for any successful collaborative software project. Git is both simple to start using and accommodating for the most complex tasks with version control. Even seasoned Git users hit roadblocks on how to handle common situations.

Advanced Git is here to help! This book is the easiest and fastest way to get hands-on experience with using Git for version control of your projects.

Take a deep dive into:

How Git actually works: After using Git for a while it’s good to discover the whys behind all of the things. Rebasing: Rebasing and squashing doesn’t have to be scary; it’s quite a useful and advanced way of merging code to support your collaborative workflow. Undoing what you’ve done: Most frustration with Git comes from not being able to undo something that you’ve screwed up. But Git has lots of ways you can go back and recover from a weird merge or commit state. Workflows in Git: Working with Git requires some rules to make sure things go smoothly across development teams. Learn the most common workflows and how to decide which one to use. And more!

One thing you can count on: after reading this book, you’ll be well-prepared to use Git in your own software development workflow!

Kotlin Coroutines by Tutorials

The importance of concurrency is discovered quite early on by people who start with Android development. Android is inherently asynchronous and event-driven, with strict requirements as to on which thread certain things can happen.

Add to this the often-cumbersome Java callback interfaces, and you will be trapped in spaghetti code pretty quickly (aptly termed as “Callback Hell”). No matter how many coding patterns you use to avoid that, you will have to encounter the state change across multiple threads in one way or the other.

The only way to create a responsive app is by leaving the UI thread as free as possible, letting all the hard work be done asynchronously by background threads.

Kotlin Coroutines by Tutorials will teach you the techniques you need to solve common programming problems using asynchronous programming.

Functional Programming in Kotlin by Tutorials

Functional programming is a powerful paradigm for building your applications. This book will teach you the fundamentals of functional programming in a practical, hands-on way, while showing you how you can safely handle errors and state changes in your programs.

Android Animations by Tutorials

This is a book about creating meaningful motion through animation in Android for developers who are familiar with the platform but want to create more visually stunning apps. Starting with simple view animations, this book will move through transition animations including shared element animations, list animations, gestures and scrolling. It ends with a taste of using animations in Jetpack Compose.

Data Structures & Algorithms in Kotlin

Learn Data Structures & Algorithms in Kotlin!

Data structures and algorithms are fundamental tools every developer should have. In this book, you’ll learn how to implement key data structures in Kotlin, and how to use them to solve a robust set of algorithms.

This book is for intermediate Kotlin or Android developers who already know the basics of the language and want to improve their knowledge.

Topics Covered in This Book Introduction to Kotlin: If you’re new to Kotlin, you can learn the main constructs and begin writing code. Complexity: When you study algorithms, you need a way to compare their performance in time and space. Learn about the Big-O notation to help you do this. Elementary Data Structures: Learn how to implement Linked List, Stacks, and Queues in Kotlin. Trees: Learn everything you need about Trees — in particular, Binary Trees, AVL Trees, as well as Binary Search and much more. Sorting Algorithms: Sorting algorithms are critical for any developer. Learn to implement the main sorting algorithms, using the tools provided by Kotlin. Graphs: Have you ever heard of Dijkstra and the calculation of the shortest path between two different points? Learn about Graphs and how to use them to solve the most useful and important algorithms.

Reactive Programming with Kotlin

Learn Reactive Programming in Kotlin with RxJava!

Not only will you learn how to use RxJava to create complex reactive applications on Android, you’ll also see how to solve common application design issues by using RxJava, RxAndroid and RxKotlin. Finally, you’ll discover how to exercise full control over the library and leverage the full power of reactive programming in your apps. Specifically, learn to handle asynchronous event sequences via two key concepts in Rx—Observables and Observers. Hone your UI development with RxJava and companion libraries to make it easy to work with the UI of your apps, providing a reactive approach to handling user events. Dig into both intermediate and advanced topics, such as error handling, schedulers, app architecture, repositories, and integrating RxJava with Android Jetpack.
