HTML5 in mobile devices
In mobile devices, HTML5 is often used for mobile websites and mobile applications on Mobile operating systems such as Firefox OS, Sailfish OS, Tizen, and Ubuntu Touch. It provides developers with tools such as Offline Web Storage, GeoLocation API, Canvas Drawing, CSS3, and many more. After observing the trend of mobile game app in the market, various people have started looking for the finest approach in game application development that can reach maximum users, is cost-effective and gives the best user-experience.

Key features for mobile devices
The AppCache and database make it possible for mobile developers to store things locally on the device and interruptions in connectivity will not affect the ability for someone to get their work done.
Offline support helps browsers cache static pages. They depend more on HTTP response headers sent by web servers to fetch HTML, CSS and multimedia required to render the web page. If everything required to render is cached, then a page loads quickly, but even if one item is not cached then everything slows down dramatically.
To provide offline support, a cache manifest file should be created to specify the offline application's resources—i.e. its pages, images, and other files needed to run offline. Typically, the manifest also contains a comment that is changed when any of the resources change, prompting the browser to refresh the cache.
CACHE MANIFEST # Version 0.1 offline.html /iui/iui.js /iui/iui.css /iui/loading.gif /iui/toolbar.png /iui/whiteButton.png /images/gymnastics.jpg /images/soccer.png /images/gym.jpg /images/soccer.jpg
The "manifest" attribute of the app's "html" element should specify the URL of the manifest file.
Sites can mark off a space on a page where interactive pictures, charts and graphs, game components, and other imaginations can be drawn directly by programming code and user interaction — no Flash or other plug-ins are required.
Video and audio streaming support
Development is in the very early stages and subject to format disruption, but sites like YouTube and Pandora could one day skip Flash entirely and bring streaming audio and video, with timed playback and further features.
navigator.geolocation.getCurrentPosition(successCallback, errorCallback, options);
Geolocation is an object which is part of Navigator object. It uses the getCurrentPosition() method. Finding location is an asynchronous operation as it requires the user’s permission for access. Hence callback functions for success and failure are required.
HTML5 capabilities in top mobile devices
A Mobile Web Metrics Report demonstrates HTML5 capabilities in mobile devices. The report checked how many HTML5 features are supported by different devices that access the mobile web.
Top 5 supported features
GeolocationAPI, offline web application support, WebStorage, CSS3 Selectors and 2D animations are the top five supported features referred to by the term HTML5 across the top 15 mobile devices in all USA, UK, Germany, Malaysia, Australia markets examined.
Top 5 partially supported features
Misc. Element types and attributes, extended user interaction concept, CSS3 in General, extended form concept, and extended video / audio support are the top five partially supported HTML5 features across the top 15 mobile devices in all USA, UK, Germany, Malaysia, Australia markets examined.
Top 5 not supported features
Microdata, 3D animation rendering, FileReader API, IndexedDB, and local Device support or the WebWorkers feature respectively are the top five HTML5 features not supported across the top 15 mobile devices in all USA, UK, Germany, Malaysia, Australia markets examined.
This report concludes that HTML5 is a welcome addition to the mobile party, but it does not negate device and OS fragmentation.
Frameworks for app development
With HTML5 and mobile web development new tools and frameworks are popping up to provide a more consistent and comprehensive HTML5 support across mobile browsers. Such HTML5 mobile web frameworks are:
Akula is an open and extensible enterprise mobile app platform for developing, securing, and governing native and hybrid apps. It is a Mobile App Server that integrates seamlessly with enterprise infrastructure, extending SOA to mobile devices. This structure enables development teams to focus on the user experience using the front-end tools and frameworks of their choice.
DaVinci is a framework that supports HTML5 mobile app development. The tool has a WYSIWYG (What You See Is What You Get) authoring environment in which users may drag and drop components to build applications. It also comes with a jQuery framework as well as other libraries and allows users to integrate open source libraries of their choice into the tool.
Google Web Toolkit
jQT (formerly 'jQTouch')
LungoJs is a framework powered by HTML5, CSS3 for iOS, Android, BlackBerry and WebOS. It has support for touch events like tap, double-tap or swipe and does not use images (including the icons), as everything is vectorized.
Sencha Touch is the first HTML5 framework for mobile devices. This framework builds web applications that make sense for mobile devices. It comes with a comprehensive UI widget library, complete touch event management with CSS transitions and an extensive data package.
Smart Mobile Studio
IBM MobileFirst Platform
IBM MobileFirst Platform is a mobile application platform that supports the development of HTML5, hybrid and native mobile applications. The MobileFirst Studio - the platform's IDE - allows mobile developers to make full use of all existing HTML5 functionality as well as further enhance these capabilities with utilities and mechanisms required by modern organizations such as encryption of locally stored data, offline authentication, combined HTML5 and native coding, 3rd-party library integration with frameworks such as PhoneGap, Sencha Touch, JQuery, and more.
Appzillon is a mobile application development platform from i-exceed technology solutions. Appzillon is used to develop hybrid mobile apps, web applications and supports native mobile capabilities such as calls, SMS, camera, calendar, accelerometer, etc. The proprietary IDE of Appzillon contains a grid based designer that allows drag-and-drop of widgets and charts to design HTML5 screens. Appzillon IDE provides an embedded simulator, adaptive widgets and deployment enabler. Appzillon supports integration with different types of enterprise services using their service formats.
Hybrid Mobile Apps
Differences from Native Apps and Mobile Web Apps
Pros and Cons of Hybrid Apps
Hybrid mobile apps have their pros and cons. When choosing what type of mobile application to develop it is important to keep these in mind.
- The app's interface and logic can be built and debugged in the web browser using an emulation framework. This could lower development costs depending on the tools required to develop native apps for the target platforms.
- The HTML5 application development with CSS3 gives the compelling structure to the interface of game app and this ensures pleasing user-interface.
- Hybrid mobile apps are more susceptible to user interface lag due to the extra layers of abstraction.
- Only a certain subset of native functionality is available which depends on the framework. All others native functions are accessible developing Plugins
- As for native apps, the hybrid code base requires recompilation and resubmission to the distribution network where it is possible to instantly update a mobile web app’s codebase.
