Android is the most popular mobile platform today and it comes with a comprehensive set of APIs that make it easy for developers to write, test and deploy apps. With these APIs you can easily show user interface (UI) components, play and record audio and video, create games and animation, store and retrieve data, search the Internet, and so on.

Click Next, according to the installation wizard, set the installation path to complete the installation process.
Then, this chapter we discusses how to install the required software and create your first application. You also learned how to create a virtual device so you can test your app in multiple devices without physical devices.
The SDK ships with an emulator so that you can test your applications without a physical device. The emulator can be configured to mimic various Android phones and tablets, from Nexus S to Nexus 9. Each instance of the configured emulator is called an Android virtual device (AVD). You can create multiple virtual devices and run them simultaneously to test your application in multiple devices.
You can download the Android Studio projects accompanying this book from the publisher’s website. To open a project, select File > Open and browse to the application directory.
