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

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?

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”.
