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 10. Performance

While developing our application, it's often easy to overlook the performance of the application on a physical device for several reasons. One may be testing a lot of functionality in a desktop browser such as Google Chrome or Safari, especially while making quick iterations. For plugin testing, the developer may elect to use an emulator most of the time, especially if they need to quickly test across multiple platforms. As useful as this strategy is, it fails in one key area: it tells us nothing about the performance of our app on a real device.

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

  • Defining performance

  • The performance difference between desktops, emulators, and physical devices

  • Profiling your app

  • Correcting input lag

  • Correcting visual stutters

  • Correcting memory problems

  • Splitting up and delegating long computations
