Recent increase in demand of the cross-platform mobile development born a few great technologies. Some of them are good, others are not, but just few of them provides native platform experience. Hybrid applications work great in this case. Taking into account responsive design makes it even better. However, users do not need “just functionality” and responsive layout any more. They need, even demand great user experience, which should be attractive, convenient, powerful, responsive and unique. During this session, I want to tell you how Xamarin and Mono help to deliver native experience for iOS, Android, Windows Phone platforms having most of your code reused between platforms and written in C#. This session will give you an overview of cross-platform development basics for iOS, Android and Windows Phone platforms using Xamarin, .NET and C# You will know: - Xamarin concept. MonoTouch & MonoDroid - Developing under Windows & Mac. Environment requirements. - Visual Studio vs Xamarin Studio - MvvmCross libraries - Utilization of Portable Class Libraries & Project Links for better code sharing

1. Cross Platform Mobile
Development using Xamarin
and C#
Develop your iOS, Android, Windows Phone apps
with .NET and C#
Alexey Strakh, EastBanc Technologies

2. Agenda
• Mono and Xamarin
• Cross Platform Environment and IDEs
• Why C#?
• Share your code
• Automated UI Testing

3. The “Build Apps Multiple Times”
Approach
•
•
•
•
Platform-specific
Multiple codebases
Slow innovation
Expensive

4. The “Write-Once-Run-Anywhere”
Approach
• Poor user experience
• Not Complete API Coverage
• High abandonment rates

6. The “Write Cross Platform” Approach

7. Xamarin
•
•
•
•
•
Native UI
Native Performance
Full API Coverage
Shared codebase
Re-use skills, teams,
tools and CODE

8. DEMO
“Hello World” app for
iOS, Android and
Windows Phone

9. How it works
• Xamarin.iOS and Xamarin.Android
• Ahead of Time Compiler for iOS
• Compile and Link for Android
• Windows Phone & Windows 8

10. Xamarin exposes 100%
of the native APIs for iOS
and Android

11. Anything you can do in
Objective-C or Java can
be done in C# with
Xamarin

12. 100% API Coverage
Native SDK Bindings

13. Cross Platform Environment
• Windows 8
• Mac OS X

14. IDEs
• Xamarin Studio
• Visual Studio
Nuget,
Resharper,
Component Store
ALM (TFS)

15. Why C#?

16. Simple Http Request

17. Why C#
• C# Syntax
• LINQ
• Task Parallel Library
• Async

18. Share your code
• Linked files
• Conditional compilation
• Portable Class Libraries

19. Share your code approach

20. DEMO
Share your code
between iOS, Android
and Windows Phone
app

21. Model-View-ViewModel
iPhone
Android
Windows Phone
Mvvm
“Digitize” your view:
•
•
•
•
•
Temperature
Date
Weather Image
Wind Speed
Actions

22. MvvmCross
• Mvvm
• Mvvm Cross Platform Framework
• Databinding for Android (AXML) and iOS (XIB)
• Plugins (Dialogs, Emails, Location, etc)

23. DEMO
Share even more code.
MvvmCross

24. Google Glass
•
•
Xamarin.Android supports Google Glass devices
Glass Development Kit (Sneak Peek) at the Component
Store

25. Xamarin TestCloud
Automatically test your iOS and Android
apps
•
•
•
•
•
•
Start immediately
Hundreds of devices
Continuous Integration
Beautiful reports
Test for fragmentation
Object-based UI testing
