      After copying Android Studio to the Applications folder, Android Studio is ready to launch. You can then remove the .dmg file from your system.

When you first launch Android Studio, it asks if you want to install Android SDK, the Android emulator, and Intel HAXM. It will also ask for the setup path for them, as shown in Figure 1.14.

If you selected Intel HAXM installation, you are asked for the amount of RAM memory you want to make available for the virtual devices, as shown in Figure 1.15.

      Installing Android Studio for Linux

      Navigate to the download page shown in Figure 1.9 to download Android Studio for Linux (android-studio-ide-141.2178183-linux.zip). After you've downloaded the file, follow these steps:

      1. Enter the following command to extract the setup file to the android-studio folder where you executed the command:

      user@ubuntu$ unzip android-studio-ide-141.2178183-linux.zip

      In this example you move the android-studio folder to the /opt directory. You can select your own home directory as well, to make it available only to you.

      user@ubuntu$ sudo mv android-studio /opt

      2. Start Android Studio with the ./opt/android-studio/bin/studio.sh command.

When you first launch Android Studio on Linux, it will display the screen shown in Figure 1.17.

      Then the setup wizard will ask for Standard or Custom installation.

      3. Select Custom installation to see the installation packages.

The wizard moves to the window shown in Figure 1.18 where you can select an Android Studio UI theme.

       Figure 1.18 shows that the IntelliJ theme has been selected for this installation.

      4. Select the Android Studio, Android SDK, and Emulator as shown in Figure 1.19.

      5. Indicate the installation path for Android SDK in the Android SDK Location field at the bottom of the dialog box, as shown in Figure 1.19. Click Finish to complete the Android SDK installation.

LAUNCHING ANDROID STUDIO FOR THE FIRST TIME

When you first launch Android Studio, you will see the Complete Installation dialog box shown in Figure 1.20, which enables you to import settings from a previous installation. Because we made a clean installation for this example, we selected the last option in the dialog box. If you have a previous installation with customization you'd like to import, you can specify your previous installation path (see the first two options in Figure 1.20).

STANDALONE SDK INSTALLATION

      In this book, the main focus is on using Android Studio for development at an advanced level. Therefore, the book covers Android SDK and tools installations together with Android Studio. If you would like to explore Android SDK and tools separately, you can get the standalone installation binaries for your choice of operating system.

      Standalone installation will help you either work with an IDE other than Android Studio, or to use the tools alone. The binaries are available at http://developer.android.com/sdk/index.html at the bottom of the page.

      As you did in this chapter, you can download the compatible binary for your operating system and follow similar installation steps to continue. After you download and extract the SDK, you can add its location to Android Studio using Settings⇨Appearance & Behavior⇨System Settings⇨Android SDK⇨Android SDK Location.

SUMMARY

      In this chapter, we wanted to make sure you have all the necessary tools to work on the examples in the following chapters. We started by providing the requirements for the basic computer system needed to install the required software.

      We then covered the installation of Android Studio for Windows, Mac OS, and Linux. We continue with what is required to begin Android application development in Android Studio in Chapter 2.
