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.

Chapter 11. Graphical Assets

No doubt you've seen the default launch screen and icon that Cordova/PhoneGap projects use. These are sufficient during development; but when you're getting ready to publish your app to the masses, you need appropriate graphical assets. These come in three categories: app icons, launch screens, and in-app graphics. We've talked to some degree already about how to make your in-app graphics responsive to the user's device in Chapter 4, More Responsive Design. Some of what we talked about does apply to your app's icon and launch screens. However, these particular assets require special configuration to ensure that Cordova/PhoneGap uses them correctly.

In this chapter, we'll cover the following topics:

  • App icon requirements

  • Creating an app icon

  • Launch screen requirements

  • Creating a launch screen

  • Configuring your app

  • Useful resources
