Android Apps Using C# With Visual Studio And Xamarin
Download as PPTX, PDF2 likes1,191 views
This document discusses using Xamarin for mobile app development. Xamarin allows using C# and sharing code across platforms like iOS, Android, and Windows. It offers a single codebase while providing full native API access and high performance. Developers can use Visual Studio for drag-and-drop UI creation and target multiple screen sizes and versions. Pre-built app components help build apps faster. Xamarin compiles to ARM binaries for iOS and uses JIT for Android. Training is available from Xamarin experts.

Editor's Notes
- #4: Xamarin is your complete mobile solution. Xamarin Platform is usually what you hear about which is building native iOS, Android, Mac, and Windows Apps all in C# However Xamarin offers a wide range of products for developers to go mobile including Test Cloud, Hockey App, and a way to learn all of mobile with University.
- #5: So we know what we want how do we get there? Let’s talk about the state of mobile development.
- #6: Multiple Teams Multiple Code Bases Expensive & Slow Positive = Great apps delivered to user’s platform Negative = Development hampered by multiple code bases & fragmentation
- #7: Unhappy Users Unhappy Developers Increase in Abandoned Apps Limited to what is implemented
- #8: UI build natively per platform, leveraging C# C# + XAML C# + XML C# + XIB One shared app logic code base, iOS, Android, Mac, Windows Phone, Windows Store, Windows
- #9: Let’s talk a bit about C# and why it is awesome.
- #10: Xamarin IS Native User Interface: Apps need to look and act correct per platform. Full SDK Access: As a developer we need to add the latest and greatest features Native Performance: Needs to be fast and fluid
- #11: Including the Free Community Edition
- #13: Let’s talk a bit about C# and why it is awesome.
- #16: All our .NET namespace and libraries are available in Xamarin, not only that Xamarin also provides 100% api coverage of each of Android’s api in its SDK which we can access in C# code.
- #18: There is no compromise on performance. Xamarin apps look and feel native because they are native.
- #19: Apple has a developer preview where Xamarin has alphas ready. Google does not offer this. Android versions are usually 4 to 8 weeks out for a stable release, but alphas and betas are usually earlier. Xamarin realizes how important having iOS ready because within 24 hours a large portion of iOS users upgrade Android on the other hand is much different. After 4 months on the market Android 4.4 only had 1% adoption
- #21: Single Solution for iOS, Android, and Windows Leverage Entire Microsoft Ecosystem: ReSharper Team Foundation Server Azure ASP.NET Favorite Code Coverage and Profiling Tools Starter Compatible Visual Studio 2012, 2013, and 2015 including Community Edition
- #23: Use all of your favorite libraries from NuGet or share and distribute your own!
- #25: If you are looking to get started will a full baked application simply head over to Xamarin’s pre-built page featuring these apps and many more!
- #29: Get started today with free 30 day trial of Xamarin at xamarin.com
