Making mobile apps with web technology

Manyoung Cho
Manyoung Cho

This document discusses the trend of building mobile apps using web technologies instead of native mobile platforms. It covers the history of web apps, how the mobile web can function like apps, and frameworks like PhoneGap that allow building cross-platform apps using HTML, CSS and JavaScript that can still access core device features. Key frameworks and standards discussed include Widgets, Chrome Web Store, Android Widget Runtime, Nokia Ovi Developer, Samsung Widget SDK, and the W3C Device APIs working group. The document argues that the mobile web is a good solution for building cross-device, cross-platform apps and that the market potential is huge given the number of mobile users and operators worldwide.
