Amazon is Now Accepting HTML5 Web Apps
Starting today, you can submit your web apps and mobile optimized web sites and have them merchandised alongside native apps on Amazon and Kindle Fire in nearly 200 countries worldwide, without any third-party software or doing any native app development. Amazon Web App Resources (http://developer.amazon.com/webapps) provides the tools that you need to optimize your web apps for Kindle Fire and Android devices to sell them in our store, including powerful tools to help you test and debug your web apps and monetize using Amazon’s In-App Purchasing API for JavaScript. Plus, we’ve made sure your web apps achieve native-like performance on Kindle Fire with our new fast web runtime, based on the Chromium engine.
