Testing and Securing Android Studio Applications

testing securing android

The book is composed by eleven chapters that on the whole are the basis to secure an Android application.

The first chapter introduces the various terms of security and the different types of vulnerability that can occur. A very important chapter because it provides the basis to understanding the rest of the book. Also, it describes the various types of tests: unit, integration, validation, system and acceptance.

The second chapter describes the architecture of Android operating system and the basics regarding the permission, Intent and content provider, highlighting the possible problems that could occur managing these badly.

Android has various tools to monitor of an application. The third chapter introduces the DDMS tool. It includes various tools like Thread monitor, Network Statistics, File Explorer, etc…all are described briefly to get an idea of what the Android SDK provides us.

The fourth chapter describes how to make common actions safe, like database communication, avoid SQL Injection, and validation of input.

The problem of the privacy is widespread in IT habit and what the fifth chapter suggests is to secure our data, saved on shared preference or storage, encrypting the data themselves. The examples of codes are very explicative and simple to understand.

The sixth chapter continues with the file of the previous chapter, adding one more security level over the network connection, recommending the HTTPS protocol that allows us to have encrypt and secure communication.

There exists several types of authentication, besides the common username and password. The seventh chapter describes the various types of authentication, based on different factors underlining these phrases:  “something the user knows”, for user and password or pin code, “something the user has”, for TOTP, and “something the user is”, for biometric authentication.

Also, the chapter describes how to use the AccountManager class to manage the possible account saved on the device.

The eighth and nineth chapters talk about testing out-and-out, differentiating between unit tests and functional tests. They start with a simple test project, up to examining all the classes that promote test developing, important to prevent bugs after publishing the application. As a test-developer, reading these chapters is very important to understand how to work with the Android platform.

The tenth chapter describes foreign libraries to facilitate the creation of tests, a thing that could speed up the writing of tests.

The last chapter explains the possible parts of application to be tested, for example the behaviour without stable internet connection or when to change the orientation of the screen.

The book, in its own small way, is great to identify the basic aspects regarding the testing and the safety of the application. Every developer should have a copy of this book in his library. Highly reccomended.
