Modern Android Security for Developers

Android apps live in a hostile environment—from rooted devices and reverse engineering to insecure networks and malicious APIs. Modern Android Security is a practical, Kotlin-first guide to building Android apps that can survive in the real world.

This book focuses on how Android apps are actually attacked and shows you modern security patterns to defend against those threats using Kotlin and current Android best practices. No unnecessary theory—only what you need to protect user data, secure communication, and harden your app against tampering and abuse.

You’ll learn how to design security as part of your app architecture, not as an afterthought.
