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 Framework Explore Android fundamentals: the operating system and the application container and its components Learn about thread safety and how to handle concurrency Write sequential, asynchronous work at a low cost Examine structured concurrency with coroutines, and learn how channels make coroutines communicate Learn how to use flows for asynchronous data processing Understand performance considerations using Android profiling tools Use performance optimizations to trim resource consumption

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. Common file and database operations Network communication with remote APIs Application lifecycle Custom views and components Threading and asynchronous work Unit and integration tests Configuring, building, and running an app on a device

A walking guidebook to the Forest of Dean Area of Outstanding Natural Beauty. From short walks of 4 miles to all-day sections of long-distance routes such as the Offa's Dyke path and the Gloucestershire Way, the 25 walks in this guidebook gives you the information needed to enjoy a wide range of walking among the rolling countryside of the Forest of Dean. 21 of the walks are circular, and 4 one-way linear routes along historic long-distance trails are described, alongside 1:25,000 OS map extracts and a wealth of background information on places of interest along the way. The walks in this guidebook take you to all corners of the forest, along shaded valleys and gorges, across wide-open farmland and over high ridges with big views. Every route is supplemented by historic, geological and wildlife information to help you make the most of your days walking in the Forest of Dean, as well as practical information on public transport and other local facilities.

Walking in the Forest of Dean

All I am is a fisherman. That’s all I’m guilty of, Your Honour. On 31 May 2010 eleven holdalls were discovered along the shore near Freshwater on the Isle of Wight; when opened they contained £53m worth of cocaine – the biggest haul ever found in UK waters. A local fishing crew was accused of waiting in the Channel for the bags to be thrown from a passing cargo ship in an operation allegedly masterminded by a local scaffolder. The Freshwater Five is a true story that cuts to the heart of the British judicial system. Did five men really attempt one of the world’s biggest drug smuggling operations – or were they simply in the wrong place, at the wrong time? Why did the police hastily alter key surveillance statements, why were logs blacked out or mysteriously left empty – and why was crucial evidence never disclosed at trial? All five men fiercely denied the allegations, but a jury rejected their version of the events. This is the story of what actually happened as told by the skipper of the crew. It’s a story that reveals the human misery of brutal prison sentences and a story that leaves the reader with one question: Does the British legal system really dispense justice?
