Overview of this book

This book starts with an introduction of Android Studio and why you should use this IDE rather than Eclipse. Moving ahead, it teaches you to build a simple app that requires no backend setup but uses Google Cloud or Parse instead. After that, you will learn how to create an Android app that can send and receive text and images using Google Cloud or Parse as a backend. It explains the concepts of Material design and how to apply them to an Android app. Also, it shows you how to build an app that runs on an Android wear device. Later, it explains how to build an app that takes advantage of the latest Android SDK while still supporting older Android versions. It also demonstrates how the performance of an app can be improved and how memory management tools that come with the Android Studio IDE can help you achieve this. By the end of the book, you will be able to develop high quality apps with a minimum amount of effort using the Android Studio IDE.

Introduction

There are some common pitfalls to avoid and some patterns that you may want to apply in order to improve the quality of your app. You have seen some of them in the previous chapters already. Also, there are some interesting tools that can be used to test and analyze your code.

In the following road map, you will notice that there are different stages that you need to complete before you can go live with your app:

The structure of your code, robustness, maintainability, and how well it complies with the functional requirements are key elements.

Functional quality is measured through software testing, for which we need to distribute our app to our beta testers. We will discuss this in Chapter 10, Beta Testing Your Apps.

Structural quality is evaluated by running unit tests and code inspections manually (peer review) or using tools such as Android Lint, which you will learn more about in the final recipe within this chapter. Now the question is how well does the architecture of the...
