If you know HTML, CSS, and JavaScript, you already have the tools you need to develop Android applications. Now updated for HTML5, the second edition of this hands-on guide shows you how to use open source web standards to design and build apps that can be adapted for any Android device.

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

• Convert a website into a web application, complete with progress indicators and other features
• Add animation with JQTouch to make your web app look and feel like a native Android app
• Make use of client-side data storage with apps that run 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 with real users, and submit the finished product to the Android Market
