Trace the ancient boundary of Offa's Dyke Path, a 283km (177 mile) National Trail along Britain's longest ancient monument — the 8th-century earthwork separating England and Wales. The trail unfolds through diverse border landscapes, from the dramatic Wye Gorge and Tintern Abbey near Chepstow, across the remote Black Mountains and Hergest Ridge, to the industrial heritage of the Clwydian Range and the seaside finish at Prestatyn. This comprehensive guidebook describes the Offa's Dyke Path from south to north and offers walkers of all abilities the chance to explore limestone gorges, mountain ridges, and borderland heritage over 12–14 days. A separate OS 1:25,000 map booklet is included, providing precise route-line mapping and ensuring you can follow Offa's ancient frontier with total confidence. The trail is divided into 12 clearly defined stages of 17–29km (11–18 miles), each with detailed route descriptions, OS mapping, and elevation profiles, allowing you to anticipate the terrainAlternative itineraries of 8 or 16 days help you tailor the Offa's Dyke Path to your perfect walking holidayPractical planning information for accommodation along the route, from country inns and B&Bs to hostels and campsites in key centres like Monmouth, Hay-on-Wye and Knighton, is provided, as well as advice on local transport linksDownloadable GPX files provide a digital navigation option, allowing you to follow the National Trail on a smartphone or GPS deviceBeyond wayfinding, the guide celebrates the path's unique story, with insights into its geology (limestone escarpments, igneous intrusions), wildlife, historical attractions, and the cultural significance of walking where Anglo-Saxon Mercia met ancient Welsh kingdoms With expert guidance from author Mike Dunn, stage-by-stage breakdowns, and the included OS map booklet, this walking guidebook equips you with everything you need to conquer Offa’s Dyke Path with ease. Discover the timeless allure of Britain's borderlands, where every ridge reveals panoramic views, ancient history, and the quiet satisfaction of completing one of the National Trails.

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.

Learn about Kotlin essentials and the Kotlin Collections FrameworkExplore Android fundamentals: the operating system and the application container and its componentsLearn about thread safety and how to handle concurrencyWrite sequential, asynchronous work at a low costExamine structured concurrency with coroutines, and learn how channels make coroutines communicateLearn how to use flows for asynchronous data processingUnderstand performance considerations using Android profiling toolsUse performance optimizations to trim resource consumption
