Introduction to Android with C# using Xamarin
This document discusses using the Xamarin platform to build Android apps using C#. Key points include: - Xamarin allows developing Android apps using C# and sharing code with other platforms like iOS and Windows. - It works by using Mono and bindings to expose the Android platform in C# and allow calling Java libraries. The compiler produces IL that runs natively on Android. - Developers can use Xamarin Studio or Visual Studio and the apps have native performance since they run natively on Android.
Introduction to Android with C# using Xamarin
- 1. Craig Dunn Developer Evangelist Xamarin craig@xamarin.com @conceptdev Androidwith C# using Xamarin
- 2. Why Xamarin.Android? aka WhyAre You Here? • Write C# apps for Android phones & tablets • Share C# with other platforms: Xamarin.iOS Windows Phone Windows Store Apps re-use C# from existing projects • Create native Android user interface • Native runtime == native performance • Use Java libraries (if required)
- 3. How Does itWork? • Mono C# + .NET implementation for Linux started in 2001/released 2004 perfect fit for today’s mobile platforms: iOS & Android • “Bindings” exposes Android as C# you can write your own to incorporate any Java • Compiler produces IL and ships a native runtime to execute it can link out unused code
- 4. How Does itWork?
- 5. Xamarin Installer • Simpleunified installer http://xamarin.com/download installs Android SDK for you • Register with Google to deploy on Play (but you can deploy directly too) http://play.google.com/apps/publish
- 6. Development Environment Support MacOS X IDE iOS Android Windows Phone Windows + Xamarin Business Edition + Mac
- 7. Android Development Environment VisualStudio Xamarin Studio
- 8. Android UI Designer VisualStudio Xamarin Studio
- 9. Android Development Environment Linkingreduces size Choose CPU arch Shared runtime for debugging only.

- 17. Recap • • • • • • Build Android appsin C# with .NET Use Xamarin Studio or Visual Studio Apps have native look and feel Apps run natively, with native performance Share code Component Store http://components.xamarin.com
- 18. What’s Next? • • • • async/await F# Portable ClassLibraries (PCL) Google Play Services In app purchasing Location services Maps v2 • Google Support Lib Drawer Navigation + more!
