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.

The dialog builder


As well as being essential to all but a few apps, Android dialogs offer a great way to see how the framework itself employs design patterns. In this case, it is the dialog builder, which strings together a series of setters to build our dialog.

In the current situation, all we really need is a very simple dialog allowing the user to confirm their selection, but dialog construction is a very interesting topic and so we will take a closer look at how it is done and how inbuilt builder patterns are used to construct them.

The dialog we are about to build will, if confirmed, take the user to another activity, so before we do that we should create that activity. This is easily done by selecting New | Activity | Blank Activity from the project explorer menu. Here we have called it CheckoutActivity.java.

Once you have created this activity, follow these two steps:

  1. The floating action button onClickListener will build and inflate our dialog. It is quite lengthy, so create a new method...
