  • 1. An Overview of Mobile HTML + JavaScript Frameworks Presented By: Sasha dos Santos Orlando Code Camp 2012
  • 2. About The Presenter• Twitter: @SashaGeekette• Blog:• Software Engineer, 3M Electronic Monitoring• ASP .NET Developer w/ interest in JavaScript, GIS and mobile• Lives near Tampa, FL• Graduate of the University of South Florida
  • 3. Frameworks
  • 4. Frameworks > JQuery Mobile• Tries to target every mobile, tablet, e-reader, desktop platform• Includes animations and components built on HTML 5 + JavaScript• Use HTML 5 data-role attribute to specify the component that a DOM element represents at runtime• Uses AJAX to transition between pages
  • 5. Frameworks > JQuery Mobile > Demo
  • 6. Frameworks > jQuery Mobile > Resources• Download:• Level of compatibility for different devices• List of data attributes
  • 7. Frameworks > Kendo UI• Similar concept and syntax to jQuery Mobile• Components adaptively render to look and behave according to expectations for a particular platform – Currently supports: Android, iOS, Blackberry – Ex. Navigation controls for iOS are displayed at the bottom, on Android – at the top
  • 8. Frameworks > Kendo UI > Demo
  • 9. Frameworks > Kendo UI > Demo
  • 10. Frameworks > Kendo UI > Demo
  • 11. Frameworks > Kendo UI > Demo
  • 12. Frameworks > Kendo UI > Demo
  • 13. Frameworks > Kendo UI > Resources• Download• Kendo UI TV
  • 14. Frameworks > PhoneGap• Build native applications using HTML + JavaScript – Applications can be placed in the various app store – Best case scenario: write one set of code & resources for all platforms• Supports: Android, iOS, Windows Phone, Blackberry, WebOS, Symbian
  • 15. Frameworks > PhoneGap• Phone Gap (classic) is used within the development environment of the mobile platform that you are targeting – Ex. Phone Gap provides JARs to use with Java, dlls to use for .NET• Phone Gap build is a new cloud-based service that builds multiple native packages in the cloud – In most cases it would not be necessary to setup development environment for each platform
  • 16. Frameworks > PhoneGap• No components – Can use components from jQuery Mobile, Kendo UI, Sencha• Native API Accelerometer Events Camera File Capture Geolocation Compass Media Connection Notification Contacts Storage Device
  • 17. Frameworks > PhoneGap > Architecture• PhoneGap shares an architecture used by many mobile frameworks• Provides a bridge between native device code and JavaScript to access native capabilities – ex. Camera, accelerometer• The application is actually running in a frameless browser window – Often called a ‘web view’ – All mobile OS SDKs offer this type of native control
  • 18. Frameworks > PhoneGap > Architecture > Plugins• Sometimes PhoneGap provides the ability to do almost everything without writing native code• It may be necessary to write some portion of code that is specific to a mobile platform• You can create a JavaScript to Native Code bridge for each platform you target
  • 19. Frameworks > Phone Gap > Architecture > Plugins Bridges Native Code: iOSJavaScript Native Code: Android
  • 20. Frameworks > PhoneGap > Demo
  • 21. Frameworks > PhoneGap > Resources• Project Website• GitHub directory of PhoneGap Plugins• Creating PhoneGap plugin for Android• Web Intent plugin for Android• Phonegap project structure using Git submodules• Crossing The PhoneGap For Multiplatform Mobile Applications
  • 22. Frameworks > Sencha Touch 2• Create mobile sites that look/feel like mobile apps OR create native packaging• Runs in webkit browsers – iOS, Android, Blackberry – No support for Windows Phone (yet), IE, Firefox• Uses MVC architecture• Like Phone Gap • uses ‘bridge’ between JavaScript and Native code • code runs in chrome-less webview (browser)
  • 23. Frameworks > Sencha Touch 2• Components such as date pickers, toolbars, tabs• Note: components do not adaptively render like Telerik’s Kendo UI but do look “mobile- ish”
  • 24. Frameworks > Sencha Touch 2• Native Device API: – Camera – Connection – Device – Geolocation – Notification – Orientation
  • 25. Frameworks > Sencha Touch 2 > Demo
  • 26. Frameworks > Sencha Touch 2 > Resources• Download• Guide• Tutorial #1• Tutorial #2• Examples on GitHub• Sencha blog posts – Includes fix for bug with Windows 7 (x64)• Look for the Examples folder in your installation
  • 27. Testing
  • 28. Testing > IIS Express• Problem: The default ASP .NET Development Server (Cassini) doesn’t allow for remote access – something required for testing mobile devices• One Solution: Switch to IIS Express – Will be default server in Visual Studio 11• Step-By-Step Instructions on My Blog :
  • 29. Testing > IIS Express > Configuration• Change Visual Studio to use IIS Express instead of ASP .NET Development Server• Change default configuration of IIS Express to allow for remote access• Configure Firewall to grant permissions to allow mobile devices to request the local site – Ex. Allow inbound requests on a particular port number, provided that the computers are on the local subnet and the computer is on a network marked as Private
  • 30. Testing > Emulators > Windows Phone• Download Microsoft Visual Studio Express 2010 for Windows Phone• Start > All Programs > Windows Phone SDK 7.1 > Windows Phone Emulator• To access localhost use IP address• Press Page Up / Page Down to enable / disable keyboard input (keyboard mapping reference)
  • 31. Testing > Emulators > Windows Phone
  • 32. Testing > Emulators > Windows Phone
  • 33. Testing > Emulators > Android• Download the Android SDK & Android Virtual Device (AVD) Manager• To access localhost use IP address• Can use telnet to send commands to the emulator – Use following command: telnet localhost 5554 – Telnet will need to be enabled on your dev machine
  • 34. Testing > Emulators > Android
  • 35. Testing > Emulators > Android > Default
  • 36. Testing > Emulators > Android > Motorola (MOTODEV)
  • 37. Testing > Emulators > Android > Samsung (Skin)
  • 38. Testing > Emulators > Android
  • 39. Testing > Emulators > Android > Resources• Java SE Development Kit• Eclipse• Android SDK• ADT Plugin for Eclipse• MOTODEV• Samsung Emulators
  • 40. Testing > Adobe Shadow• Wirelessly connect to multiple mobile devices and preview, inspect, debug in real time• Supported Environments: – Development Computer: Windows 7 & Mac OS X – Development Browser: Chrome – Mobile Devices: Any Android or iOS device, on same network as the development computer
  • 41. Testing > Adobe Shadow
  • 42. Testing > Adobe Shadow• To test sites on mobile devices during development, use IIS Express and Adobe Shadow• Change default configuration of web site or web project to use computer name or IP address instead of localhost
  • 43. Testing > Adobe Shadow > Resources• Download• Video• Using Visual Studio + IIS Express + Adobe Shadow to Test Local Websites on Mobile Devices
