AndroidManifest.xml: At the top of the manifest file you’ll find.Navigate to these three files and check out their contents: Understanding the codeīefore the hands-on part of this tutorial, take some time to understand the codebase you’ll build on. You’ll implement the functionality throughout this tutorial. The app isn’t interactive yet because the starter project only consists of UI and some basic code. Extract and open the starter project in Android Studio.īuild and run.
