Preface

With a rapid increase in the use of mobile devices everywhere, developing for Android takes advantage of this trend to reach the widest market available to any mobile platform. Along with creating awesome Android apps, Xamarin allows the use of the mature .NET Framework. .NET is a massive framework that is supported on almost all platforms, including iOS, Windows, Mac OS X, and Linux.

Developing apps with Xamarin.Android allows you to use and reuse your code and skills on different platforms, making you more productive in any sort of development. Although not a write-once-run-anywhere framework, Xamarin provides native platform integration and optimizations. There is no middleware; Xamarin.Android talks directly to the system, taking your C# and F# code directly to the low levels.
