Preface

Mobile applications have become very popular in the last few years thanks to a huge increment in the use of mobile devices. From a developer's point of view, Android has become an important source of income thanks to the different app repositories, such as Google Play and Amazon Appstore.

With an increase in the number of applications available, users have become more demanding about the features of the applications they are going to use. A solid testing of the application and its security aspects are the key factors in the pursuit of success for an application. Bugs and security issues are obviously not features that help your application do well in the increasingly more exigent market of Android.

In this book, you are going to learn how to turn your Android application into a solidly debugged and secure application. To achieve this, you will learn how to use Android Studio and its most important features: testing and security.
