android-studio-ide-181.5056338-windows.exe to start the installation process. The installer responded by presenting the Android Studio Setup dialog box shown in Figure 1.
Clicking Next took me to the following panel, which provides the option to decline installing an Android Virtual Device (AVD).
I chose to keep the default settings. After clicking Next, I was taken to the Configuration Settings panel, where I was asked to choose where to install Android Studio.
I kept the default installation location and clicked Next, and was greeted with the Choose Start Menu Folder panel.
I kept the default setting and clicked Install. The following Installing panel appeared:
Clicking Show details causes the names of files being installed and other activities to be displayed. When installation finished, the Installation Complete panel appeared.
After clicking Next, the installer presented the Completing Android Studio Setup panel.
To complete the installation, I left the Start Android Studio box checked and clicked Finish.
Running Android Studio
The first time Android Studio runs, it presents a Complete Installation dialog box that offers the option of importing settings from a previous installation.
I chose not to import settings (the default selection) and clicked OK, and was rewarded with the following splash screen:
I also observed the following Finding Available SDK Components message box.
At this point, Android Studio presented the following Android Studio Setup Wizard dialog box:
I clicked Next, and the wizard invited me to select an installation type. I kept the default standard setting.
I was then given the opportunity to choose a user interface theme.
I kept the default IntelliJ setting and clicked Next. Android Studio next provided the opportunity to verify settings.
I clicked Finish and Android Studio began the process of downloading SDK components.
It can take several minutes for this part of the setup to finish. Clicking Show Details might relieve some boredom by revealing the various files being downloaded and unzipped.
For my AMD-based computer, an unpleasant surprise awaited after the components had completely downloaded and unzipped:
My options are to either put up with the slow emulator or use an Android device to speed up development. In Part 3 I'll show you how I resolved this issue.
Finally, I clicked Finish to complete the wizard. The Welcome to Android Studio dialog box appeared.
This dialog box is used to start up a new Android Studio project, work with an existing project, and more. It can be accessed by selecting Android Studio from the Windows Start menu, or the equivalent on another platform.
Your first Android Studio mobile app
The quickest way to get to know Android Studio is to use it to develop an app. We'll start with a variation on the "Hello, World" application: a little mobile app that displays a "Welcome to Android" message.
In the steps that follow, you'll start a new Android Studio project and get to know the main window, including the editor window that you'll use to code the app in Part 2.
Starting a new project
From our setup so far, you should still have Android Studio running with the Welcome to Android Studio dialog box. From here, click Start a new Android Studio project. Android Studio will respond with the Create New Project dialog box shown in Figure 19.
Enter W2A (Welcome to Android) as the application name and javajeff.ca as the company domain name. On my desktop, I observed C:\Users\JEFF\AndroidStudioProjects\W2A as the project location. Click Next to select your target devices.
Android Studio lets you select form factors, or categories of target devices, for every app you create. I kept the default setting.
Click Next, and you will be given the opportunity to choose a template for your app's main activity. For now we'll stick with Empty Activity. Select this template (if necessary) and click Next.
Next you'll customize the activity:
Enter W2A as the activity name and main as the layout name, and click Next to complete this step.
The next time you create an app for the chosen target device category, you'll probably discover that Next is disabled and Finish is enabled.
The first time you use Android Studio, you'll discover that it has to download some files related to its constraint layout, which is used to build responsive user interfaces:
Android Studio enables Finish after downloading the constraint layout files. Click this button and Android Studio takes you to the main window.
