The installer then saves the Android SDK Tools into a default location (or you can specify the location).
you will need to refer to the SDK directory later, when setting up the ADT plugin and when using the SDK tools from the command line
Once the tools are installed, the installer offers to start the Android SDK Manager.
When you open the Android SDK Manager, it automatically selects a set of recommended packages. Simply click Install to install the recommended packages.
For easy access to the SDK tools from a command line, add the location of the SDK's tools/ and platform-tools to your PATH environment variable.
