Answer the question "Can we build this for ALL the devices?" with a resounding YES. Learn how to build apps using seven different platforms: Mobile Web, iOS, Android, Windows, RubyMotion, React Native, and Xamarin. Find out which cross-platform solution makes the most sense for your needs, whether you're new to mobile or an experienced developer expanding your options. Start covering all of the mobile world today. Understanding the idioms, patterns, and quirks of the modern mobile platforms gives you the power to choose how you develop. Over seven weeks you'll build seven different mobile apps using seven different tools. You'll start out with Mobile Web; develop native apps on iOS, Android, and Windows; and finish by building apps for multiple operating systems using the native cross-platform solutions RubyMotion, React Native, and Xamarin. For each platform, you'll build simple, but non-trivial, apps that consume JSON data, run on multiple screen sizes, or store local data. You'll see how to test, how to build views, and how to structure code. You'll find out how much code it's possible to share, how much of the underlying platform you still need to know, and ultimately, you'll get a firm understanding of how to build apps on whichever devices your users prefer. This book gives you enough first-hand experience to weigh the trade-offs when building mobile apps. You'll compare writing apps on one platform versus another and understand the benefits and hidden costs of cross-platform tools. You'll get pragmatic, hands-on experience writing apps in a multi-platform world. What You Need: You'll need a computer and some experience programming. When we cover iOS, you'll need a Mac, and when we cover Windows Phone you'll need a computer with Windows on it. It's helpful if you have access to an iPhone, Android phone, and Windows Phone to run the examples on the devices where mobile apps are ultimately deployed, but the simulators or emulator versions of those phones work great.

Starting with an app built with the basics of the Xamarin.Forms toolkit, you'll go step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices. You'll start by introducing a core separation between the app's user interface and its business logic by applying the MVVM pattern and data-binding. Then you focus on building out a layer of plugin-like services that handle platform-specific utilities such as navigation and geo-location, and on how to loosely use these services in the app with inversion of control and dependency injection. Next you connect the app to a live web-based API and set up offline synchronization. Then, you delve into testing the app logic through unit tests. Finally, you set up Visual Studio App Center for monitoring usage and bugs to gain a proactive edge on app quality. What you will learn Implement the Model-View-View-Model (MVVM) pattern and data-binding in Xamarin.Forms mobile apps Extend the Xamarin.Forms navigation API with a custom ViewModel-centric navigation service Leverage the inversion of control and dependency injection patterns in Xamarin.Forms mobile apps Work with online and offline data in Xamarin.Forms mobile apps Test business logic in Xamarin.Forms mobile apps Use platform-specific APIs to build rich custom user interfaces in Xamarin.Forms mobile apps Explore how to improve mobile app quality using Visual Studio AppCenter Who this book is for This book is intended for C# developers who are familiar with the Xamarin platform and the Xamarin.Forms toolkit.

Political Islam in Tunisia uncovers the secret history of Tunisia's main Islamist movement, al-Nahda, from its origins as a sociocultural movement in the 1960s to the present. Banned until the popular uprisings of 2010- 11 and the overthrow of Ben Ali's dictatorship, al-Nahda has until nowbeen impossible to investigate. This is the first in-depth account of the movement, one of Tunisia's most influential political actors and an important source of regional leadership. Based on more than four years of field research, over 400 interviews, and access to private archives, Anne Wolf masterfully unveils the evolution of al-Nahda's ideological and strategic orientations within changing political contexts and, at times, conflicting ambitions amongst its leading cadres.She also explores the challenges to al-Nahda's quest for power from both secularists and Salafis. As the first full history of al- Nahda, this book is a major contribution to the literature on Tunisia, Islamist movements, and political Islam in the Arab world. It will be indispensable reading foranyone seeking to understand the forces driving a key player in the country most hopeful of pursuing a democratic trajectory in the wake of the Arab Spring.
