Learn how to make mobile native app development easier. If your team frequently works with both iOS and Android—or plans to transition from one to the other—this hands-on guide shows you how to perform the most common development tasks in each platform. Want to learn how to make network connections in iOS? Or how to work with a database in Android? This book has you covered.

In the book’s first part, authors Shaun Lewis and Mike Dunn from O’Reilly’s mobile engineering group provide a list of common, platform-agnostic tasks. The second part helps you create a bare-bones app in each platform, using the techniques from part one.

Get professionally developed and curated recipes for 20 of the most common tasks for functionality in modern native iOS and Android applications. With this practical book, developers can use an easily translatable set of instructions for completing routine functionality in both platforms in a way that follows best practices. Authors Shaun Lewis and Mike Dunn provide step-by-step direction to help you create a fully-functional application using modern practices and designs that will utilize those tasks. The development of the apps will be laid out side-by-side, so that the friction usually involved in switching between platforms while developing is greatly reduced. By the end of this book, you’ll have developed apps for both iOS and Android with exactly the same core features, as well as some additional features that are relevant and unique to each app’s operating system.

Developing applications for the Android mobile operating system can seem daunting, particularly if it requires learning a new programming language: Kotlin, now Androidâ??s officialdevelopment language. With this practical book, Android developers will learn how to make the transition from Java to Kotlin, including how Kotlin provides a true advantage for gaining control over asynchronous computations.

Authors Pierre-Olivier Laurence, Amanda Hinchman-Dominguez, G. Blake Meike, and Mike Dunn explore implementations of the most common tasks in native Android development, and show you how Kotlin can help you solve concurrency problems. With a focus on structured concurrency, a new asynchronous programming paradigm, this book will guide you through one of Kotlin''s most powerful constructs, coroutines.
