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.

Extending platform scope

The support libraries we have been working with throughout the book do a marvelous job of making our apps available on older devices, but they do not work for all situations, and many new innovations simply cannot be realized on some older machines. Taking a look at the following device dashboard, it is obvious that we would like to extend our apps back to API level 16:

Extending platform scope

We have seen how the AppCompat library enables our apps to run on platforms even older than this, but we have to avoid using some features. For example, the view.setElevation() method (along with other material features) will not work below API level 21 and will cause the machine to crash if it is called.

It would be tempting to think that we could simply sacrifice such features for the benefit of reaching a wider audience, but fortunately, this is not necessary as it is possible to detect dynamically which platform our app is running on with the following conditional clause:
