In Bulletproof Android, Godfrey Nolan brings together comprehensive, up-to-date best practices for writing apps that resist attack and won't leak information. Unlike other Android security books focused on "breaking" code, Bulletproof Android focuses on strengthening code security throughout the entire development lifecycle. Nolan covers authentication, networking, databases, server attacks, libraries, hardware, and more. He illuminates each technique with code examples, offering expert advice on implementation and trade-offs.
