Learn everything you need to know to get started building Android apps with Google's Android Studio and Android SDK. David Gassner starts with a brief look at the history of Android and the latest iteration, Android 6.0 (aka Marshmallow). Then, after you set up your development environment, he shows you how to prepare virtual and physical devices for testing and create a new Android project: a shopping app for a fictional sportswear company. Using this example app, David demonstrates how to define the user interface with XML and widgets, control the app behavior with Java, set up "between screen" navigation, and display lists of data and images. Plus, learn how to enable support for the different screen sizes and pixel densities of the 24,000+ Android models on the market today.
