ANDROID_HOME is Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead.

Configure the ANDROID_SDK_ROOT environment variable

1. Open the Windows Control Panel.
2. Click on User Accounts, then click User Accounts again
3. Click on Change my environment variables
4. Click on New... to create a new ANDROID_SDK_ROOT user variable that points to the path to your Android SDK:

The SDK is installed, by default, at the following location:

%LOCALAPPDATA%\Android\Sdk

You can find the actual location of the SDK in the Android Studio "Settings" dialog, under Appearance & Behavior → System Settings → Android SDK.
