A session at the Sela Developer Practice delivered jointly with Shai Raiten and Ofir Makmal from Sela. We provided an overview of the three primary mobile development paradigms -- native mobile apps (Windows Phone, iOS, Android), Xamarin, and PhoneGap.

Pages
Navigation
ListViews and binding

8. Xamarin
Founded in 2011 by Novell ex-employees
Based on the Mono project – launched on 2001
Brings the .NET Framework to Linux and OS X
Xamarin took it to the next step: all major
platforms – iOS, Android, Linux, OS X
Officially partnered with Microsoft
Over 460,000 developers live, 20,000 paying
customers, 120 consulting partners
Used by more than 20% of Fortune 500 companies

9. Why Xamarin?
Reuse your company’s current development
investment
Keep using Visual Studio (or Xamarin Studio)
Same-day support for all new API’s
100% platform API coverage
All latest C# goodness –
LINQ, asyncawait, TPL
Average of 75% code sharing!
Scan your code for conformance:
scan.xamarin.com

10. Xamarin Application Architecture

11. PhoneGap
PhoneGap is an open source mobile
development framework
Developed by Nitobi Software
Purchased by Adobe
Renamed to Cordova after the shift to Adobe
Enables building mobile device applications
using the Web technology stack –
HTML, CSS, and JavaScript

12. Hybrid Apps
A PhoneGap application is considered hybrid
They are neither truly native, nor purely web-based
All layout rendering is done via the Web View
Supports 7 platforms

13. What Is PhoneGap All About?

14. Getting Started with PhoneGap
Set up your development environment
PC, Mac
Xcode, Eclipse, Visual Studio
SDKs, JDKs, plug-ins
Same as for Native Development
Adobe® PhoneGap™ Build – upload
your HTML5, CSS, and JavaScript assets to a
cloud service which does the work of compiling
for you
