Explore the world of Android app development. This training course prepares you to create your very first Android app—helping you understand the technologies at work and prepare your computer for development and testing. Learn how to configure Android Studio, the Android SDK, and emulator software, and study the different files in a typical Android app: build scripts, the app manifest file, permissions tags, and icons. Finally, learn how an app is built from the bottom up, with screens, activities, and layouts. David Gassner shows how to define the visual presentation with XML and widgets, and control the logic with Java code. This simple overview is designed to provide you with everything you need to know to understand the Android development process. Later courses in the Essentials series concentrate on the specific skills you need to master.
