Summary

In this chapter, we saw how to create and edit the user interface layouts using both the graphical and the text-based editors. We finished our first small application, and we upgraded it with some basic components. You should now be able to create a simple layout and test it with different styles, screen sizes, and screen resolutions. You also learned about the different available UI themes. Finally, you learned about events and learned how to handle them using listeners.

In the next chapter, you will learn about some useful tools available in the Android Studio. We will use the SDK Manager frequently to install different packages. You will also learn about the AVD Manager for different virtual devices to test your applications on. We will generate Javadoc documentation for our project using the Javadoc utility, and you will learn about the version control systems available in Android Studio.
