Android Design Patterns and Best Practice

By: Kyle Mew

Overview of this book

Are you an Android developer with some experience under your belt? Are you wondering how the experts create efficient and good-looking apps? Then your wait will end with this book! We will teach you about different Android development patterns that will enable you to write clean code and make your app stand out from the crowd. The book starts by introducing the Android development environment and exploring the support libraries. You will gradually explore the different design and layout patterns and get to know the best practices of how to use them together. Then you’ll then develop an application that will help you grasp activities, services, and broadcasts and their roles in Android development. Moving on, you will add user-detecting classes and APIs such as gesture detection, touch screen listeners, and sensors to your app. You will also learn to adapt your app to run on tablets and other devices and platforms, including Android Wear, auto, and TV. Finally, you will see how to connect your app to social media and explore deployment patterns as well as the best publishing and monetizing practices.

Preface

Chapter 8. Composing Patterns

We have seen how patterns can be used to manipulate, organize, and present data, but this data has been fleeting, and we have not yet considered how to ensure data persists from one session to the next. In this chapter, we will look at how this is done using internal data storage mechanisms. In particular, we will explore how users can save their preferences, making the app simpler and more fun to use. Before we do this, we will begin the chapter by examining the composite pattern and its uses, particularly when it comes to constructing hierarchical structures such as Android UIs.

In this chapter, you will learn how to do the following:

  • Construct a composite pattern

  • Create a layout with composer

  • Use static files

  • Edit application files

  • Store user preferences

  • Understand the activity life cycle

  • Add unique identifiers

One of the most immediate ways we can apply design patterns to an Android project is layout inflation, and back in Chapter 6, Activating Patterns, we used...
