4 HTML5 VS Native appall hybrid apps developed with cross-platform HTML5 wrapped in a native container. They were not built from scratch in platform-specific languages like Objective-C or Java. Pure HTML5 web apps cannot appear in app markets like the iTunes App Store or Google Android Market, but these apps can because they have that native wrapper. This wrapper also gives these apps access to native capabilities like the camera, microphone, contact list, or notification system that are off limits to the browser.
6 A primary reason that many companies are not already jumping on the HTML5 bandwagon is the belief that HTML apps cannot access native device features. Indeed, pure mobile web apps (i.e., those that run in the browser – not hybrid ones) are currently restricted in their access to features such as the camera, microphone, address book, and so forth. And while there is work in progress at the W3C to allow web apps to access such device services, mobile browsers do not currently provide such functionality – a key requirement for many innovative mobile apps.
7 Access to device features is not the only difference between hybrid apps and mobile web apps. Another important difference is that hybrid apps are mostly distributed through app stores: You don’t browse to a hybrid app – you download and install it.
13 Supported platformsPhoneGap currently supports development for the operating systems Apple iOS, Google Android, HP webOS, Microsoft Windows Phone, Nokia Symbian OS and RIM BlackBerry
14 WHY PHONEGAPMobile development is a mess. Building applications for each device--iPhone, Android, Windows Mobile and more--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, they’re future-proofed to work with browsers as they evolve.
15 Appache software foundation The PhoneGap code was contributed to the Apache Software Foundation (ASF) under the name Apache Callback in October It is currently under incubation until it can become a full Apache project. Through the ASF, future PhoneGap development will ensure open stewardship of the project. It will always remain free and open source under the Apache License, Version 2.0.
