Mastering PhoneGap Mobile Application Development

By: Kerri Shotts

Overview of this book

PhoneGap is a useful and flexible tool that enables you to create complex hybrid applications for mobile platforms. In addition to the core technology, there is a large and vibrant community that creates third-party plugins that can take your app to the next level. This book will guide you through the process of creating a complex data-driven hybrid mobile application using PhoneGap, web technologies, and third-party plugins. A good foundation is critical, so you will learn how to create a useful workflow to make development easier. From there, the next version of JavaScript (ES6) and the CSS pre-processor SASS are introduced as a way to simplify creating the look of the mobile application. Responsive design techniques are also covered, including the flexbox layout module. As many apps are data-driven, you'll build an application throughout the course of the book that relies upon IndexedDB and SQLite. You'll also download additional content and address how to handle in-app purchases. Furthermore, you’ll build your own customized plugins for your particular use case. When the app is complete, the book will guide you through the steps necessary to submit your app to the Google Play and Apple iTunes stores.

This isn't because HTML was really originally built with accessibility in mind (it wasn't), but because many of the assistive technologies that have been developed had to cope with the web content that wasn't accessible. In these cases, the assistive technology had to glean as much information as possible from the markup. Some HTML elements, such as a, input, select, option, and so on, provide a lot of useful information. Screen readers have developed an understanding of how these are often used and how to interact with them over the years.

HTML 2.0 brought about the famous alt attribute. Here were the first glimmerings of accessibility on the web, but it wasn't added solely for accessibility. The alt attribute is meant to render when the original content can't be rendered...
