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.

A sandwich builder pattern


The builder pattern is purpose-built for combining simple objects to form one complex object, and this forms a perfect analogy of making a sandwich. We encountered a generalized builder pattern earlier in the book, but now we need to adapt it for a specific function. Furthermore, we will be connecting the pattern to a working UI so that a sandwich can be constructed according to user selections rather than the set meal demonstrated in previous builder examples.

Applying the pattern

To keep the code short and simple, we will only create two concrete classes of each ingredient type, and we will use buttons and a text view to display the output rather than a recycler view. Simply follow these steps to create our sandwich builder pattern:

  1. Begin with the following interface:

    public interface Ingredient { 
     
        public String description(); 
     
        public int kcal(); 
    } 
    
  2. Create these two abstract implementations of Ingredient. They are empty...
