Build and run the app on real and virtual devices.Create source code for all of the app's components. Write code using the Java programming language.You can place UI elements on the screen using the layout editor, or you can write code directly in the Extensible Markup Language (XML). Define a layout for each screen that has UI elements.Create the project in Android Studio and choose an appropriate template.

When you are ready to start coding, you use Android Studio to go through the following steps: To show what a UI would look like and how it would work, use drawings, mockups, and prototypes. You may want to sketch user interfaces (UIs) for the various app functions. This chapter describes how to develop applications using Android Studio, which is an integrated development environment (IDE) for Android.Īn Android app project begins with an idea and a definition of the requirements necessary to realize that idea. Running the app on an emulator or a device.Lesson 3: Testing, debugging, and using support libraries
