  1. Ecosystem Apps INNOVATIVE CROSS-PLATFORM SOLUTIONS Sergey Seletsky Abiliton™ Senior Software Engineer

  2. Agenda • Why? • What is an ecosystem? • Problems? • WinRT with HTML5 for other... • Cross-platform frameworks • Xamarin • Titanium • Portable apps • AppMobi • Specific integrated API • Apps integration • Apps Stores • Ecosystem architecture • Conclusions

  3. What is an ecosystem?

  4. Enterprise App Ecosystem App Hub IT organization Windows Phone 1. Registration 1. Device Enrollment 2. Signing Tools 2. Get apps 3. Cert and Enterprise ID 1. Develop App 2. Package and sign • Registration • Enterprise registers with App Hub • Enterprise downloads app tools • Microsoft notifies CA of pending enterprise registration • Vets enterprise • CA checks that vetting is complete, and generates a certificate for enterprise 3. App Catalog 4. Create Token

  5. Why ?

  6. Smartphone Market Share

  7. 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

  8. Cross-Platform Devices • Phones • iOS – iPhone, Touch • Android • Blackberry • Windows Phone 7 • Tablets • iPad • Android

  9. 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

  10. Problems?

  11. Cross-platform frameworks • Xamarin • Titanium • Portable apps • AppMobi • PhoneGap

  12. Xamarin

  13. Asynchronous code before MyApi.OnSomeMethod += () => { InvokeOnMainThread( (result) => { textView.Text = result; }); } MyApi.SomeMethodAsync();

  14. async/await textView.Text = awaitMyApi.GetUrlAsync( “http://softserveinc.com”);

  15. С# vsObjective-C Objective-C: // … [button addTarget:self action:@selector(touchHandler:) forControlEvents:UIControlEventTouchUpInside]; // … -(void) touchHandler:(id)sender { textView.text = @"some text"; }

  16. С# vsObjective-C C#: btn.TouchUpInside += (s, e) => { textView.Text = "Clicked!"; } ;

  17. C# vs Java Java: button.setOnClickListener( new View.OnClickListener() { public void onClick(View v) { textView.setText(“Clicked”); } } );

  18. C# vs Java C#: button.Click += (s, e) { textView.Text = “Clicked!”; } ;

  19. C# vs {0} • Simply • Cleaner • Develops very quickly • From Java sand pours • [[[[AfterObjective-C] world :square]as:very]and all: in the colon];

  20. 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

  21. Compilationprocess • Compile your code, libraries, BCL, wrappers over native methods in IL • Youcan use any language IL • Convertedinto machine code using AOT compilation • Added to app code with Mono Runtime and everything else

  22. 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

  23. RestrictionsAOT • 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

  24. 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

  25. C#API • Subscribe to Events • Setting Properties • Familiar names varbtn = newUIButton(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);

  26. 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)

  27. 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); } }

  28. AppStructure • Virtually same in native app • AppDelegate, UIWindows, ViewControllers • To describe UI also uses nib files

  29. Developmentenvironment – Visual Studio

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

  31. Windows Apps

  32. Use of opportunities of Windows OS Win32 API Vista Bridge Windows Bridge .NET Framework • Windows Presentation Foundation • Windows Communication Foundation • Windows Workflow Foundation

  33. Windows 8 platform Desktop Apps Metro style Apps HTML JavaScript HTML / CSS XAML View JavaScript (Chakra) C C++ C# VB Model Controller C# VB C++ WinRT APIs Devices & Printing Communication & Data Graphics & Media System Services .NET / SL Internet Explorer Win32 Application Model Windows Core OS Services Core

  34. Installation Store Apps Store backend Files / Assets Single instance store Manifest.xml Package Manager stage BlockMap Store install package Execution Engine Signature Registration Information Zip Central Directory register Extension Handler

  35. Transitions between states App are given several seconds to sleep App is not notified suspending Running App Suspended App Terminated App User Launches App Low Resources resuming App is notified with continued Splash screen Code gets to run No code runs App not running

  36. Process isolation Process2 Process1 Local context Local context Web context Web context AppData AppData Contracts Local Local Temp Temp Roaming Roaming Direct APIs Brokers OS User data Devices Communications Handlers Tiles Cryptography … …

  37. Languageprojection IInspectable Object C++ App Projection IUnknown C#/VB App CLR Projection HTML App Chakra Projection Windows Metadata

  38. Collections IInspectable C++ App STL-style Projection IUnknown IVector<T> Array IVectorView<T> IObservableVector<T> C#/VB App CLR IEnumerable (T) style Projection IInspectable IUnknown HTML App Chakra JavaScript Projection IMap<T> Associative Collection IMapView<T> IObservableMap<T>

  39. Asynchrony in Windows 8 • All that is more than 50 milliseconds – asynchronously • Windows Runtime: IAsyncOperation<T> • JavaScript: Promises • C++: Parallel Patterns Library • VB/C#: async/await

  40. Threading MainUI thread Taskfactory Windows UI Object Windows Object Windows Object App Code App Code App Code
