The initial installation of Android Studio includes a basic SDK which includes operating system images, compilers and other tools you need to build Android apps.

1. From the Welcome screen, click the Configure button and then click SDK Manager button. When the SDK Manager opens, you should see several options already selected. If you plan to do development for Android TV or Android Wear, you will need to select those options as well. The latest version of Android is installed when Android Studio is installed.
2. Check these tools to ensure you have the latest version of each installed:
   1. Android SDK tools
   2. Android platform tools
   3. Android Build tools
   4. Documentation for Android SDK
   5. SDK platform
   6. Samples for SDK
   7. Google API
   8. Google API Intel x86 Atom System Image
   9. Source for Android SDK
   10. Android Support Repository (Java libraries and other resources that are need for new apps)
   11. Google USB Driver (Windows only)
   12. Intel x86 Emulator Accelarator (HAXM installer)
       
       TIP: Select only the options that you are going to use (e.g., Intel x86 Atom System Image)
       NOTE: A USB driver is not needed for the Mac because it will automatically connect to a physical Android device. System images are virtual device images use with an emulator.
       
       
       NOTE: It is recommended that you create a few AVDs with different API levels and hardware configurations so that an app can be tested on different Android OSs. If you have a small monitor, select the Scale display to real size checkbox so that you can set the emulator to  a smaller size. An Android SDK Platform and a ARM System Image is the minimum components for an given Android version.
       
       
       NOTE: The SDK Tools tab will show what versions of the build tools are installed. If you attempt to use a project that is based on an OLDER SDK version, you will be prompted to install that copy of the SDK tool.You can have multiple versions of SDK Tools installed to support DIFFERENT projects.
       
       NOTE: The SDK Update Sites tab list the web sites that Android Studio use. You don't have anything to do in this tab.
