Building Android Apps with HTML, CSS, and JavaScript

Book description

If you know HTML, CSS, and JavaScript, you already have the tools you need to develop Android applications. This hands-on book shows you how to use these open source web standards to design and build apps that can be adapted for any Android device -- without having to use Java.

You'll learn how to create an Android-friendly web app on the platform of your choice, and then convert it to a native Android app with the free PhoneGap framework. Discover why device-agnostic mobile apps are the wave of the future, and start building apps that offer greater flexibility and a broader reach.

  • Learn the basics for making a web page look great on the Android web browser
  • Convert a website into a web application, complete with progress indicators and more
  • Add animation with jQTouch to make your web app look and feel like a native Android app
  • Take advantage of client-side data storage with apps that run even when the Android device is offline
  • Use PhoneGap to hook into advanced Android features -- including the accelerometer, geolocation, and alerts
  • Test and debug your app on the Web under load with real users, and then submit the finished product to the Android Market
