Android Architecture, Protection, and Development Best Practices

This course is included in our On-demand training solution.

Overview

Given the relatively open nature of the Android development environment, developers ought to have a clear understanding of the OS structure, as well as how to securely protect application code. In this course, you will be introduced to the Android environment and overall architecture, and will also be presented with a basic understanding of key Android OS security features. You will also learn how to protect Android application code and will learn about best practices to employ when developing secure Android applications.

Target Audience

Application developers on the beginner and intermediate level seeking to create and deploy secure Android applications
