Build HTML5-based hybrid applications for Android with a mix of native Java and JavaScript components, without using third-party libraries and wrappers such as PhoneGap or Titanium. This concise, hands-on book takes you through the entire process, from setting up your development environment to deploying your product to an app store.

Learn how to create apps that have access to native APIs, such as location, vibrator, sensors, and the camera, using a JavaScript/Java bridge—and choose the language that gives you better performance for each task. If you have experience with HTML5 and JavaScript, you’ll quickly discover why hybrid app development is the wave of the future.

Set up a development environment with HTML, CSS, and JavaScript tools
Create your first hybrid Android project, using Eclipse IDE
Use the WebView control to host your hybrid application
Explore hybrid application architecture, including JavaScript/Java communication
Build single-page applications, using JavaScript libraries such as Backbone and Underscore
Get optimization tips and useful snippets for CSS, DOM, and JavaScript
Distribute your application to Google Play and the Amazon Appstore
