Once you've created your Android application and designed a user interface, you're ready to learn how to manage your app. This course prepares you to handle events and manage navigation in your Android app. David Gassner begins by explaining how to work with events. He describes the activity lifecycle—what actually happens when a screen appears and disappears—and shares some techniques for working with events using Java objects, lambda expressions, and open source libraries. Next, he covers how to manage navigation, start activities with explicit intents, send data to an activity, and open other apps with implicit intents.
