This document presents on PhoneGap, an open-source mobile development framework. PhoneGap allows developers to build mobile apps using HTML, CSS, and JavaScript and deploy them across various platforms. It bridges the gap between web technologies and native mobile development. Key features of PhoneGap discussed include writing once and deploying to multiple platforms, accessing device hardware, and using standards-based web technologies. Advantages are cross-platform development and leveraging native features, while limitations include not having latest features and relying on community support.

Introducing PhoneGap!!!! Applications built with PhoneGap are not just like normal mobile web sites. PhoneGap applications are able to interact with mobile device hardware, such as the Accelerometer or GPS, in ways that are unavailable to normal web applications. PhoneGap applications are also built and packaged like native applications, meaning that they can be distributed through the Apple App Store or the Android Market. 6
So What Is PHONEGAP??? Phonegap is an open-source mobile development framework developed by Nitobi Software and IBM. It enables all mobile developers to build applications for mobile devices using JavaScript, HTML and CSS. 7
Why PhoneGap??? Mobile development is a mess. Building applications for each device--iPhone, Android, Windows Mobile etc requires different frameworks and languages. One day, the big players in mobile may decide to work together and unify third-party app development processes. Until then, PhoneGap will use standards-based web technologies to bridge web applications and mobile devices. Plus, because PhoneGap apps are standards compliant, theyre future-proofed to work with browsers as they evolve. PhoneGap is an open source implementation of open standards. That means developers and companies can use PhoneGap for mobile applications that are free, commercial, open source, or any combination of these. 8

HOW PHONEGAP WORKS??? Build your app once with web-standards. Based on HTML5, PhoneGap leverages web technologies developers already know best... HTML and JavaScript. Wrap it with PhoneGap Using the free open source framework or PhoneGap build you can get access to native APIs. Deploy to multiple platforms! PhoneGap uses standards-based web technologies to bridge web applications and mobile devices. 10
HOW PHONEGAP WORKS?(Conti.) 11
Glance On The PHONEGAP BUILD Service Using PhoneGap we can create Build Native Web-apps. 12
Glance On The PHONEGAP BUILD Service(Conti.) There are some things the web does very well. There are also some things native apps do very well. PhoneGap aims for the union of these. Write app using HTML, CSS or JavaScript. Upload it to the PhoneGap Build service. Get back app-store ready apps for Apple iOS Android, Palm, Symbian and BlackBerry. Current development to also support Windows, MeeGo and Bada. PhoneGap Build service is currently in beta testing and is free to register and use will remain free for open source projects. 13
With PhoneGap you can, 14
Advantages of using PhoneGap You can use the single codebase for your cross platform applications. You can leverage the hardware specific features such as Geolocation, Vibration, Accelerometer, Contact Support and Sound. Open source can be altered or extended by anyone. Open Source community is actively contributing new modules which can potentially save you time and money. Requires knowledge of common web technologies (HTML, CSS, JavaScript) rather than multiple distinct mobile platforms. Currently offers the widest major platform coverage among other similar frameworks. 15
Limitations of using PhoneGap Since PhoneGap is designed to support multiple platforms, it will not have the new features available as soon as they are available in the SDK. Essentially, it is always catching up. Several platform core features may still not be available via PhoneGap. Just like any other Open Source platform / SDK, PhoneGap heavily relies on the community to contribute various modules. While these modules will work fine out of box, there may be challenges with the support and maintenance with those modules. 16
Conclusion Platform-specific native applications seem to be slowly fading away into a niche or need-basis. HTML/JS is easier to deal with than Java (fact!) If you want to produce an app and/or deploy to multiple platforms at reasonable cost then PhoneGap is the way to go. 17
