14. What platforms to support?

15. What platforms to support?
u Depends on project
u Depends on users
u Depends on region
u Depends on budget
u Not necessarily all at once

16. Hardened devices

19. Types of development
u Native
u iOS SDK’s
u Android SDK’s
u Windows SDK’s
u Hybrid
u PhoneGap
u Sensha
u Cordova
u Appcelerator
u Ionic
u Many, many more…
u Web Apps
u HTML 5

20. Native development
u SDK (Software development kit) provided by Google, Apple or
Microsoft
u Specific per platform
u Tooling
u Language(s)
u Controls
u UI Guidelines
u Interaction Guidelines
u Entire code base per platform

21. Hybrid development
u Third party tools that work with platform SDK’s
u One language
u Can write on all platforms, building requires specific OS
u Share resources
u Write logic one time

22. Web development
u No specific requirements
u Any platform / language
u HTML
u Scripting

23. Pro’s
Native
- Performance
- Device API’s
- Support
- Look and feel
Hybrid
- Cross platform
- Write once *
- Use one language /
tool
- Access to device
Web
- Little development needed
- Control

24. Con’s
Native
- Write / maintain
multiple times
- Different approach
- Different language
- Can be expensive to
built everything
multiple times
Hybrid
- Performance
- Write once (fix
everywhere)
- Look and feel
- Scripting
- Testing more difficult
Web
- Not an app
- No offline support
- No (or limited) access to
device

25. Our approach
u As stated before it depends….
u If possible use Xamarin

27. Anything you can do in Objective-C, Swift or Java
can be done in C# and Visual Studio with Xamarin

28. Xamarin’s Unique Approach
Shared app logic,
platform-specific UI,
all in C#
Shared App Logic in C#
iOS C# UI Android C# UI Windows C# UI
Shared App Logic
§ Platform-specific UI code in C#
§ Shared app logic code in C#
§ Fine-grain control over the app user
interface
§ Good for apps with sophisticated UX
requirements (complicated gestures,
animations, design)

29. Native Performance
Xamarin.iOS does full Ahead Of Time (AOT)
compilation to produce an ARM binary for
Apple’s App Store.
Xamarin.Android takes advantage of
Just In Time (JIT) compilation on the
Android device.

30. Completely up-to-date with device OS releases
u Always up-to-date with
Apple and Google API
releases.
u Track record of offering
same-day support: iOS 5, iOS
6, iOS 6.1, iOS 7,iOS 7.1, iOS
8 and iOS 8.x releases.
u The only cross-platform
solution with support for the
Google Glass SDK, Android
Wear, Amazon Fire TV and
Apple Watch.

52. Grow

53. “
”
If you’re not using ASO to increase your
app’s search ranking, you’re missing
out on the largest discovery channel
available to your app.
SOMEONE CLEVER
63% (iOS) of app customers report browsing in the app store to discover new
apps.

54. AppStore Optimization
u Description is important
u Carefully pick your keywords
u App reviews vs developer feedback
u Leverage Store specific options to promote your app
u Localize your AppStore listings

55. And we’re done…
SERVICE

56. App Maintenance
u OS / Platform updates or new releases
u Updates to libraries
u Support for new devices and device families (think wearables)
u Bug fixes
