Mastering Android Studio 3

By: Kyle Mew

Overview of this book

Android Studio is an Integrated Development Environment (IDE) designed for developing Android apps. As with most development processes, Android keeps resources and logic nicely separated, and so this book covers the management of imagery and other resources, and the development and testing tools provided by the IDE. After introducing the software, the book moves straight into UI development using the sophisticated, WYSIWYG layout editor and XML code to design and test complex interfaces for a wide variety of screen configurations. With activity design covered, the book continues to guide the reader through application logic development, exploring the latest APIs provided by the SDK. Each topic will be demonstrated by working code samples that can be run on a device or emulator. One of Android Studio's greatest features is the large number of third-party plugins available for it, and throughout the book we will be exploring the most useful of these, along with samples and libraries that can be found on GitHub. The final module of the book deals with the final stages of development: building and distribution. The book concludes by taking the reader through the registration and publication processes required by Google. By the time you have finished the book, you will be able to build faster, smoother, and error-free Android applications, in less time and with fewer complications than you ever thought possible.

Testing and Profiling

If there was only one reason to choose Android Studio over other IDEs, it could easily be claimed that it was due to its powerful debugging and testing tools. These tools range from a simple Logcat reporting to complex testing mechanisms based on the JUnit framework. In addition to tools to help us identify bugs in our code, Android Studio also has a host of very smart, performance monitoring tools that allow developers to fine-tune projects and maximize their efficiency.

This chapter will explore each of these processes in turn, beginning with simple inline debug calls and then moving on to the different types of JUnit tests and concluding by taking a look at how to monitor the performance of our apps under a variety of conditions.

In this chapter, you will learn how to:

  • Configure a Logcat debug filter
  • Create local unit tests
  • Build instrumented tests
  • Record...
