Google Apps Lookup (Android) - Lookup allows Google Apps for Business and Google Apps for Education users to find and contact any user in their corporate domain. Users can type or speak name, domain alias (e.g., jdoe) or email address, and Lookup will find the contact information for the user from the Global Address List and provide rich, structured contact data. Users can tap to contact the person via email, chat, phone or open a map of the address.
Lookup requires the "Shared Contacts" feature enabled by the organization administrator in the Google Apps Control Panel.
