PhoneGap is an open source framework that allows developers to build cross-platform mobile apps using standard web technologies like HTML, CSS, and JavaScript. It works by wrapping web content in a native container, allowing apps to access native device features like the camera, geolocation, contacts, and more. Developers create web content and compile it into native apps for iOS, Android, Blackberry and other platforms. This allows developers to leverage their web skills to build mobile apps that work across platforms.

2. Background
• Evolution of Mobile Web.
• Formats: WAP, cHTML, mHTML.
• Limited by Phone’s web browser.
• Manufacturer dependent proprietary web
browser.
• WAP: “Where Are the Phones?”
• Limited resources, capabilities & bandwidth.
• Inconsistent form factors (screen size, color
depth, bitmap support, plugin?).

6. Developing for Mobile Web
• Inconsistency:
• Layout, screen resolution, form factors,
capabilities, bandwidth, plug-in
• Proprietary APIs
• Caveat: Cross platform web browsers (Webkit,
Mozilla, Opera)
• Limited in Scope
• Web browser “Silo”
• Self-contained & away from the rest of the OS
• Secure but quite useless Ph.P

7. Native Phone App?
• Learning Curve:
• New SDK, New Language, New Paradigmn
• OS Dependent quirks, limitations, conventions
• Weapon of Choice (which platform?):
• Significant investment in time & money
• Egg in one basket?

8. What is PhoneGap?
• Leverages on what we web developers knows best
- HTML & Javascript.
• Gives us access to the phone’s native APIs &
features - Geo-location, Vibration, Accelerometer,
Sound, Contacts, Camera, etc...
• “Wraps the web view with a container. This container
gives the view access to APIs available on the device
that may not be available on the Web view alone”.
