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 facade pattern


The facade pattern is perhaps one of the simplest of the structural pattern to understand and create. As its name suggests, it act as a face that sits in front of a complex system. When programming client code, we never have to concern ourselves with the complex logic of the rest of our system, if we have a facade to represent it. All we have to do is deal with the facade itself, and this means we can devise facades to maximize simplicity.

Think of the facade pattern like the simple keypad you might find on a typical vending machine. Vending machines are very complex systems, combining all manner of mechanical and physical components. However, to operate one, all we need is to know how to punch in a number or two on its keypad. The keypad is the facade and it hides all the complexity behind it. We can demonstrate this by considering the imaginary vending machine, outlined in the following steps:

  1. Start by creating the following interface:
