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

The bridge pattern


The main difference between adapters and bridges is that adapters are built to correct incompatibilities that arise from our design, whereas a bridge is constructed before, and its purpose is to separate an interface from its implementation, so that we can modify and even replace the implementation without changing client code.

In the following example, we will assume that users of our sandwich builder app will have a choice of open or closed sandwiches. Apart from this one factor, these sandwiches are identical in that they can contain any combination of fillings, although to simplify matters, there will only be a maximum of two ingredients. This will demonstrate how we can decouple an abstract class from its implementations so that they be modified independently.

The following steps explain how to construct a simple bridge pattern:

  1. Begin by creating an interface like the one seen here:

    public interface SandwichInterface { 
     
        void makeSandwich(String filling1...
