Field Enablement:Real World SolutionsA Look Inside

Field Enablement – What It Is

What it is:

The modernization of field force applications.

Delivering and collecting rich content within complex data and processing environments.

Real World Solutions – A Look Inside• Architectures such as one illustrated here have been

successful enabling mobile field workers in several scenarios:

• Building Inspectors enforcing safety regulations on equipment used in public settings

• Fire Prevention Professionals testing water supply pressure and flow

• Healthcare Providers visiting patients and managing continuing education requirements

• Insurance Agents engaging customers in video chat + real-time collaboration

• Lab Scientists reviewing and verifying data in highly regulated settings

• Patent Attorneys trying cases and managing client billing

• Personal Trainers reviewing data captured during client workouts

• Technical Sales Reps providing secure demos of NDA-only products and services

• We’ll discuss the architecture of these solutions, and then drill into the details of each

Mobile Development – Unification on C#

• Mobile development projects can pose a daunting set of competing priorities for the team to balance:

• Device vendors want developers to code exclusively for their devices

• Device vendors begrudgingly support HTML5 standards

• http://caniuse.com for feature-by-feature details• Users want great app experiences• Project sponsors want to reach broadest array of

devices with least amount of code

• Xamarin provides a great solution for balancing these completing priorities by unifying mobile development on the C# programming language

• can use Visual Studio on Windows as development tool

• can use Xamarin Studio on OS X as development tool

• For many scenarios, this approach is optimal

Portable Class Libraries – Complier-Checked Sharing

• Portable Class Libraries facilitate sharing across mobile platforms

• Non-UI code can be reused across devices – compiler be used can ensure compatibility as shown:

• This facilitates development using design patterns such as M-V-VM or MVC

• Reusable frameworks for M-V-VM enable sharing Model and ViewModel code across platforms

Shared Components – Accelerating Development

• Xamarin provides an extensive catalog of components reusable across mobile platforms

• http://components.xamarin.com• at last count there were 217 components available –

can be filtered by platform, price, rating, etc.• These components can provide simple, tested, solutions for

common scenarios• authentication, analytics, cloud-storage, etc.

• There are also platform-specific components with Xamarin bindings available

Native Apps – No-Compromise User Experiences

• Xamarin can reach the native frameworks for popular mobile platforms:

• iOS, Android, Windows, OS X

• Thus, Xamarin can provide direct access to native platform features like:

• Android’s LocationManager, iOS’s Asset Library, etc.

• Native user interface gestures, idioms, and programming patterns are preserved

• They’re just mapped to C# language equivalents

• This enables Xamarin developers to deliver great user experiences and to have access to nearly all* device features* might need to build a Xamarin binding to wrap some

deeper features

WinRT, .NET




Cloud Service

Dependency Injection – Balancing Native/Shared

• Often, portable code will need to interact with platform-specific code

• How to avoid taking platform dependencies while maintaining shareable logic?

• Dependency Injection solves this problem by defining portable abstractions that are implemented for each platform

• Abstractions are defined in the Portable Class Library• Implementations are provided for each platform• IoC containers can be configured to connect interface

to implementation on each platform

• These techniques enable developers to strike the right balance between native code implementations and portable abstractions

Testing – Covering the Broadest Range of Users• Xamarin Test Cloud enables

automated app testing across devices and OS versions

Pre-Release Deployment – Getting App to Testers

for iOS apps for Android/Windows apps• TestFlight works well for getting iOS apps to

friendly community of testers• need proper distribution certificate + provisioning

profile first

• File sharing (or even email attachments) can be quite effective

• but note that attachments can be quite large and very binary
