Enterprise App Ecosystem

2. Signing Tools

3. App Catalog

1. Registration

1. Develop App

2. Package and sign

1. Device Enrollment

2. Get apps

4. Create Token

3. Cert and Enterprise ID

Registration1. Enterprise registers with App

Hub2. Enterprise downloads app tools3. Microsoft notifies CA of

pending enterprise registration4. Vets enterprise5. CA checks that vetting is

complete, and generates a certificate for enterprise

Native Wrappers• Phonegap • Titanium• appMobi• Create native apps using HTML5• Provide API’s (Hooks to get out of the

sandbox)• Work across platforms (mostly)• Can be submitted to app stores

www.softserve.ua

Cross-Platform Devices

• Phones– iOS – iPhone, Touch– Android– Blackberry– Windows Phone 7

• Tablets– iPad– Android

www.softserve.ua

Mobile Capabilities That Influence Apps• GeoLocation• PIM Contacts• Camera• Barcode• Date/Time Picker• Native Menus• Tab Bar• Navigation Bar• Signature Capture

• Bluetooth• Calendar• Push• Screen Rotation• Native Maps• Alert• Audio File Playback• Ringtones• NFC

Asynchronous code before

MyApi.OnSomeMethod += () => {InvokeOnMainThread( (result) =>

{textView.Text = result;

});}

MyApi.SomeMethodAsync();

www.softserve.ua

async/await

textView.Text = await MyApi.GetUrlAsync(

“http://softserveinc.com”);

www.softserve.ua

С# vs Objective-C

Objective-C:

// …[button addTarget:self

action:@selector(touchHandler:) forControlEvents:UIControlEventTouchUpInside];// …

-(void) touchHandler:(id)sender {textView.text = @"some text";

}

www.softserve.ua

С# vs Objective-C

C#:

btn.TouchUpInside += (s, e) => {textView.Text = "Clicked!";

} ;

www.softserve.ua

C# vs Java

Java:

button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) { textView.setText(“Clicked”); }

});

www.softserve.ua

C# vs Java

C#:

button.Click += (s, e) {textView.Text = “Clicked!”;

} ;

www.softserve.ua

C# vs {0}

• Simply• Cleaner• Develops very quickly• From Java sand pours• [[[[After Objective-C] world : square]

as: very] and all: in the colon];

www.softserve.ua

What is Monotouch

• Mono framework with AOT compilation for ARM processors and Bindings to Native API

• Code is written in C #• UI is native tongue, through C #

wrapper• Development environment Visual

Studio

www.softserve.ua

Compilation process

• Compile your code, libraries, BCL, wrappers over native methods in IL

• You can use any language IL • Converted into machine code using

AOT compilation• Added to app code with Mono

Runtime and everything else

www.softserve.ua

AOT vs JIT

• Usually in. Net and Mono native code generated at run - Just In Time compilation

• In iOS you can not compile code on JIT, only static linking

• But we already know the architecture (ARM) so you can compile the code in advance - Ahead Of Time compilation

www.softserve.ua

Restrictions AOT

• No Emit, but remains Reflection• Some specific designs will not work,

because compiled on JIT• Generic Virtual Methods

– P/Invokes in Generic Types– Some LINQ expressions

www.softserve.ua

Linking

• At time of compilation of IL BCL undertakes only code that is actually used

• Similarly, you can cut out unused code in their libraries

• Need to reduce the size of app

www.softserve.ua

C# API

• Subscribe to Events• Setting Properties• Familiar names

var btn = new UIButton(new RectangleF(0, 0, 200, 80));btn.Enabled = true;btn.SetTitleColor(UIColor.FromRGB(255, 255, 0), UIControlState.Selected);btn.TouchUpInside += delegate {

// your code} ;window.Add(btn);

www.softserve.ua

Wrappers over native methods

Monotouch: • It all comes down to P/Invoke method

objc_msgSend with the appropriate parameters

Mono for Android: • Used JNI (Java Native Interface)

www.softserve.ua

Wrappers over native methods

public virtual bool Enabled{

[Export("isEnabled")]get{

// …return Messaging.bool_objc_msgSend(base.Handle,

UIControl.selIsEnabled);}[Export("setEnabled:")]set{

// …Messaging.void_objc_msgSend_bool(base.Handle,

UIControl.selSetEnabled_, value);}

}

www.softserve.ua

App Structure

• Virtually same in native app• AppDelegate, UIWindows,

ViewControllers• To describe UI also uses nib files

www.softserve.ua

Development environment – Visual Studio

www.softserve.ua

Cross-platform

• Sharing in 30-60 percent of the code• Combining basic mobile functionality• There are various MVVM frameworks
