Nearby Notifications help users to discover what’s around them, by surfacing location-specific notifications for apps and websites, with the advantage of no prior app install is required.
Nearby Notifications allow to notify a HTTPS URL, trigger an app install through Play Store, or trigger an app intent to launch an app that is already installed and perform a specific action.
From the beacon point of view, a nearby notification is a kind of attachment that can be associated to a registered iBeacon UUID, Eddystone UID or Eddystone EID. As mentioned before, this attachment allows to associate a web URL, an app install or an app with web fallback.
