Must Read – Unleash the power of HTML 5 Canvas for gaming

May 15, 2012 All, CSS 3, Gaming, HTML, HTML5, JavaScript, KnowledgeBase, social gaming, Web No comments

An excellent article discusses about using HTML5 canvas for building browser based games using only HTML and Javascript. The <canvas> element is used to draw graphics, on the fly, on a web page.

The power of HTML5 Canvas is that you can draw any 2D or 3D content within the canvas region using powerful HTML5 Javascript API’s.

Recommend reading article which would give you good understanding on HTML5 Canvas.

Mobile Application Development

April 7, 2012 All, ANDROID, CSS 3, HTML, HTML5, iOS, iPhone, JavaScript, JQuery Mobile, Mobile Frameworks, Mobile SDK, mobile web, Mobile-Development, Windows Mobile, Windows Phone, Windows Phone 7 1 comment , , , , , , , , , , , , , ,

Mobile Applications are rapidly developing segment in the global mobile sector. Developing mobile applications targeting different mobile platforms such as Windows Phone, iOS, Android, Blackberry and Bada(Samsung’s Proprietary OS) is the trend setter now.

Quoting from Wikipedia

Mobile application development is the process by which application software is developed for small low-power handheld devices such as personal digital assistants, enterprise digital assistants or mobile phones or smart phones. These applications are either pre-installed on phones during manufacture, downloaded by customers from various mobile software distribution platforms, or web applications delivered over HTTP which use server-side or client-side processing (e.g. JavaScript) to provide an "application-like" experience within a Web browser.

[Wikipedia]

Why is it so different from other application development?

Or

Why do we need to give special care when doing mobile development?

Mobile devices have certain limitations in terms of hardware, they have limited screen display, limited space for applications to operate and network capabilities. These limitations will vary in different models as the Mobile ecosystem is very large and there is innumerous amount of devices in the world. So we need to give special care in developing the mobile applications ensuring the compatibility across all the platforms.

Some of the things we need to consider when we do mobile development are:

  • Small screen size and mobile ecosystem – This makes it difficult or impossible to see text and graphics dependent on the standard size of a desktop computer screen.
  • Lack of windows/ multi-tasking – On a desktop computer, the ability to open more than one window at a time allows for multi-tasking and for easy revert to a previous page. Historically on mobile web, only one page can be displayed at a time, and pages can only be viewed in the sequence they were originally accessed. Latest mobile platform releases such as iOS, Android and Windows Phone are supporting multi tasking capability, which allows you to run more than one applications parallel, yet only one application can be displayed on the screen.
  • Navigation – Most mobile devices do not use a mouse like pointer, but rather simply an up and down function for scrolling or touch inputs, thereby limiting the flexibility in navigation.
  • Hardware and Resource limitation – all the upcoming mobile devices are having Dual Core or Quad core mobile processors with decent amount of memory. But still if you need you device to function well and be responsive, you should develop application in such a way it will be using low memory foot print.
  • Targeting Or Supporting wide variety Mobile Platforms/ Execution environments – this is the most complicated or important feature set we should be taking in to consideration when developing an application. Android, iOS, BlackBerry, HP webOS, Symbian OS, Bada from Samsung, and Windows Mobile support typical application binaries as found on personal computers with code which executes in the native machine format of the processor (the ARM architecture is a dominant design used on many current models).

Also read this article on 7 Limitations when designing for mobile: http://baymard.com/blog/mobile-design-limitations 

For Technical point of view we can differentiate mobile applications in to three categories

1. Native Applications

Native applications developed against native platform APIs and It would be having full(or limited for some platforms) access to the device capabilities. Each of the platforms for mobile applications also has an integrated development environment which provides tools to allow a developer to write, test and deploy applications into the target platform environment.

Examples are using Applications developed using Native/Platform Mobile SDK’s such as iOS SDK, Android SDK, Windows Phone SDK etc.  Windows Mobile, Android, HP webOS and iOS offer free SDKs and integrated development environments to developers. These applications will be able to utilize or interact with all device capabilities.

 

Five reasons for developing Native Applications:

  • Performance
  • Offline Mode
  • Findability / Discoverability ( through a central location such as Apple’s AppStore , Google’s Market, Windows Phone Market etc)
  • Device Attributes
  • Monetization

The disadvantage is obviously the development cost. No two mobile platforms can share the same mobile application, and there are too many Mobile operating systems (or platforms) existing in the market. If you develop a mobile application to market it widely, you need to develop that in  Symbian, Mac iPhone, Android, Blackberry and Windows mobile.

2. Mobile Web Applications  / Browser based Applications

Mobile Web applications are web sites that are scaled down/optimized to display on a mobile web browser. Mobile web applications are developed in such a way keeping in mind less payload delivery per each request. These applications are typically a scale down version of actual website which you can browse over any desktop browser such as Internet Explorer, Chrome, Firefox and Opera.

Every action mobile web application makes a round trip to server.

The advantages of having mobile web application is that:

  • Server Driven – we have full control on the website. and we can customize it any time, so that user will get the latest look and feel.
  • Targeting multiple platforms & connectivity – most of the mobiles and smartphones have a browser.  One-third of humankind currently has access to the Internet through a mobile device. That makes it easy to deliver our applications in any platform.
  • It enables services to take advantage of mobile device capabilities such as clicking on a phone number to call it or add it to the device address book. It can provide location-sensitive content. Location technologies can enable location-sensitive information be provided to a user. This can reduce the steps required for the user to reach useful content, and so makes it accessible with the least amount of effort.
  • For users, they don’t have to download an application or any maintenance updates, but instead “call up” a URL via their mobile browser which instantly delivers the most up-to-date application to their device.
  • Cross platform compatibility.
  • low development cost.

and the disadvantage is the bandwidth limitations and the limitations of Mobile websites, which does not access your Phone’s components like your Address book, Camera, etc.

The Mobile Web refers access to the world wide web, i.e. the use of browser-based Internet services, from a handheld mobile device, such as a smartphone, a feature phone or a tablet computer, connected to a mobile network or other wireless network.

Traditionally, access to the Web has been via fixed-line services on large-screen laptops and desktop computers. The shift to mobile Web access has been accelerating with the rise since 2007 of larger multitouch smartphones, and of multitouch tablet computers since 2010.

Both platforms provide better Internet access and browser- or application-based user Web experiences than previous generations of mobile devices have done.

Mobile Web access today still suffers from interoperability and usability problems. Interoperability issues stem from the platform fragmentation of mobile devices, mobile operating systems, and browsers. Usability problems are centered around the small physical size of the mobile phone form factors (limits on display resolution and user input/operating). 

[Wikipedia]

3. Hybrid Mobile Applications

Hybrid Mobile Applications are Applications that use BOTH browser interfaces and native mobile components. With HTML5 and JavaScripts, now the browsers are becoming capable of accessing a phone’s built in features like contacts, camera etc.

There are mobile frameworks based on HTML5 and JavaScript’s that would be able to access the device features such as Accelerometer, Compass, Contacts, Camera and device file system etc. Some popular such mobile frameworks are PhoneGap, Appcelerator’s Titanium etc. These frameworks helps in developing applications that would able to target most of the mobile platforms such as “iOS”, “Android”, “Windows Phone”, “Symbian” and “Blackberry”.

Appcelerator Titanium is a platform for developing mobile, tablet and desktop applications using web technologies.

Key to successful Hybrid Apps:

  • Make the experience feel like a native application.
  • Take advantage of the enhanced features.
  • Don’t simply release a hybrid version of the mobile web site.
  • Optimize performance

 

Mobile world is growing and you can see lots of opportunities for innovation. If you are a fan of building mobile applications go ahead and develop something that is in your dreams and leave it over to the rest of the world to carry forward.

 

Resources for Developing mobile applications:

PhoneGap (was called by the name Apache Callback, but now Apache Cordova) is an open-source mobile development framework produced by Nitobi, purchased by Adobe Systems. It enables software programmers to build applications for mobile devices using JavaScript, HTML5 and CSS3, instead of lower-level languages such as Objective-C. The resulting applications are hybrid, meaning that they are neither truly native (all layout rendering is done via the webview instead of the platform’s native UI framework) nor purely web based (they are not just web apps but packed for appstore distribution, and have access to part of the device application programming interface).

http://phonegap.com/ 

 

Appcelerator Titanium is a platform for developing mobile, tablet and desktop applications using web technologies. Appcelerator Titanium is developed by Appcelerator Inc.

Appcelerator Titanium Mobile is one of several phone web based application framework solutions allowing web developers to apply existing skills to create native applications for iPhone and Android. Yet, while using the familiar JavaScript syntax, developers will also have to learn the Titanium API, which is quite different from familiar web frameworks such as jQuery.

Beginning HTML5 Development with Visual Studio 2010

January 3, 2012 .NET, .NET Framework, All, ASP.NET, ASP.NET MVC, ASP.NET MVP, CSS, CSS 3, HTML, HTML5, jQuery, JQuery Mobile, Microsoft, Mobile-Development, VisualStudio, VS2008, VS2010 3 comments

Recently I was doing some research works on HTML5 development using ASP.NET  on Visual Studio 2010.  Really liked the cool features HTML5, CSS3 and Javascript API’s. Major part of my research was around building mobile web applications using jQuery Mobile and Responsive Web.

Quick Intro of HTML5

  • HTML5 will be the new standard for HTML, XHTML, and the HTML DOM.
  • The previous version of HTML came in 1999. The web has changed a lot since then.
  • Today, some elements in HTML 4.01 are obsolete, never used, or not used the way they were intended to. These elements are deleted or re-written in HTML5.
  • HTML5 is still a work in progress. However, most modern browsers have some HTML5 support.
  • HTML5 is a cooperation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).
  • WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.

Some rules for HTML5 were established:

  1. New features should be based on HTML, CSS, DOM, and JavaScript
  2. Reduce the need for external plugins (like Flash)
  3. Better error handling
  4. More markup to replace scripting
  5. HTML5 should be device independent
  6. The development process should be visible to the public

and that’s  enough about HTML5.

If you are not aware of HTML5, you can read more about HTML5 later through the below links

http://dev.w3.org/html5/spec/Overview.html

http://en.wikipedia.org/wiki/HTML5

http://www.w3schools.com/html5/default.asp

Coming to jQuery Mobile…

  • jQuery Mobile, is a framework that will help you rapidly and confidently develop mobile app user interfaces across popular mobile device platforms like iOS and Android, is perhaps the most popular project out there.
  • The framework boasts a lightweight code base (weighing in at 20KB when minified and gzipped) and a huge bevy of standard user interface elements that mobile device users are accustomed to, such as switches and sliders.
  • JQuery Mobile, hails from a royal family of frameworks and spawned from community of jQuery, the most famous cross platform JS library.
  • Works great with mobile browsers from Symbian, Android through iOS to Blackberry, Window Phone 7, WebOS.
  • Visit http://jquerymobile.com for more details

JQueryMobile has been included as a standard binary include in upcoming ASP.NET MVC 4.0 by Microsoft.

Okey, that was little bit over talk about jQuery Mobile :-), lets look at the point I want to make.

Recent months there is an increasing trend of mobile web applications using HTML5, as most of the recent mobile browsers supports partially or up to certain level on HTML5 capabilities. The idea is that Multi Platform targeted mobile web application development.

 

To enable HTML5 syntax intelli- sense in Visual Studio 2010 we have the following options to try

1.) Visual Studio 2010 Service Pack 1 – Visual Studio 2010 was originally released without HTML5 support, so does SP1 finally add support for it, to some extent.

The entire HTML5 specification isn’t supported but most of the new elements and attributes are. That means you get both intellisense and validation for HTML5 with SP1.

2.) HTML 5 Intellisense for Visual Studio 2010 and 2008 Extension from  Mikhail Arkhipov (Microsoft)

Since Visual Studio 2010 doesn’t have complete support for all HTML5 and CSS3 syntax’s we can try this add-in to enable the support in Visual Studio 2010 and 2008.

3.) Web Standards Update for Visual Studio 2010 SP1

Web Platform and Tools team, spearheaded by Mads Kristensen  has released this update in Visual Studio Gallery. This adds better support for HTML5, CSS3 and new JavaScript features to ALL versions of Visual Studio.

Web Standards Update provides the much wanted HTML5 & CSS3 support to Visual Studio 2010 SP1. It brings VS 2010 intellisense & validation as close to W3C specification as we could get via means of an extension.  The most notable supported features by this extension are:

HTML5 – Video, Audio, Input Type, Drag & Drop, WAI-ARIA, Microdata, Schema.org
Browser API – GeoLocation & Local Storage
CSS3 – 2D Transforms, 3D Transforms, Animations, Background & Borders, Basic Box Model, Basic UI, Behavior, Color, Flexible Box Layout, Fonts, Paged Media, Hyperlink Presentation, Line, Lists, Marquee, Media Queries, Multi Column, Namespaces, Presentation Levels, Ruby, Selectors, Speech, Syntax, Template Layout, Text & Transitions. It also supports vendor specific prefixes like -ms, -webkit & -moz.

Refer to  Scott Hanselman’s blog for more detailed update : http://www.hanselman.com/blog/AnnouncingTheWebStandardsUpdateHTML5SupportForTheVisualStudio2010Editor.aspx

Get Web Standards Update for Microsoft Visual Studio 2010 SP1

4.) A Little Old Way 

To enable Intellisense to work with HTML 5, perform the following steps:

  1. Download the HTML5 support package for Visual Studio 2008 from the Visual Web Developer team here.
  2. Copy the html_5.xsd in C:Program Files (x86)Microsoft Visual Studio 10.0Common7Packagesschemashtml
  3. Edit the correct registry file and replace 9.0 with 10.0
    The file will look like this ( 64 bit VS 2010 Ultimate for me ):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftVisualStudio10.0Packages{1B437D20-F8FE-11D2-A6AE-00104BCC7269}SchemasSchema 23]
“File”=”htmlhtml_5.xsd”
“Friendly Name”=”HTML 5”
“URI”=”http://schemas.microsoft.com/intellisense/html-5”

  1. Run the registry file to merge it with your registry.
  2. Open Visual Studio 2010
  3. Go to Tools->Options->Text Editor->HTML->Validation
  4. Select target as HTML 5

This would allow you to get Intellisense for your HTML 5 based projects.

referenced from http://amargalla.com/Blog/general/169-html-5-with-visual-studio-2010

Not only that Visual Studio Gallery is having lots of cool Extensions such as Mobile Ready Templates using HTML5, and other extension templates you could try.  Some of them are….

Mobile Ready HTML5 MVC.NET

Creates a mobile ready MVC 3.0 project using the Razor’s view engine and jQuery mobile. Both mobile and desktop versions can be tested using mobile emulators or browsers.

CSS 3 Intellisense Schema

jQuery Mobile Site

Yet another Mobile Ready ASP.NET MVC Template. Use this MVC 3 Razor Site Template with jQuery Mobile boilerplate layout, scripts and CSS referenced to create adaptable websites for a variety of devices.

So we do have wide variety of ways we can enable HTML5 support when using Visual Studio 2010. Of course we already having HTML5 support included with ASP.NET MVC 3.0 Tools Update,  but the above options will help us in enabling Intellisense support for normal ASP.NET applications as well. 

Hope this will help you with your HTML5 development..

Happy Coding !!!

Reference links for HTML 5 and Browser’s Capabilities

May 22, 2011 All, CSS 3, General, HTML, HTML5, Mobile-Development, Web No comments

While in today’s discussion by Harish Ranganathan about HTML 5, I couldn’t recollect a website name that lists out demos of all HTML 5 capabilities and browser compatibilities. It’s a typical developer brain I have and I forgot the website name that moment to voice out.

http://www.html5demos.com Where you can see all demos and examples of HTML 5.

Hope this would be helpful for your guys to explore further.

http://www.html5test.com, will test your browser capabilities and show a report, what are all the capabilities your browser supports.
