Course description
Before you begin to write code, you need to understand why security is so essential in today’s modern mobile app. In this course, you will learn about the most common security mistakes developers make when creating apps. You will learn which mobile app vulnerabilities are considered the most dangerous and what can be done to defend against those dangers. You will explore Android security architecture and be introduced to Kotlin, a new open-source programming language developed by JetBrains (with some help from Google). We will wind up this course by examining a deliberately vulnerable Kotlin Android app that we will use in our activities throughout this path.
