1 2 Android Geofencing Sample 3 =================================== 4 5 When the user enters the vicinity of the Android building (B44) or the Yerba Buena 6 Gardens near the Moscone center in San Francisco, a notification silently appears on their 7 wearable with an option to check in. This notification automatically disappears when they leave 8 the area, and reappears the next time they are at one of these locations. 9 10 Introduction 11 ------------ 12 13 Geofencing combines awareness of the user's current location with awareness of 14 nearby features, defined as the user's proximity to locations that may be of 15 interest. To mark a location of interest, you specify its latitude and longitude. 16 To adjust the proximity for the location, you add a radius. The latitude, 17 longitude, and radius define a geofence. You can have multiple active 18 geofences at one time. 19 20 To use geofencing, start by defining the geofences you want to monitor. 21 Although you usually store geofence data in a local database or download 22 it from the network, you need to send a geofence to Location Services as 23 an instance of [Geofence][2], which you create with `Geofence.Builder`. Each 24 Geofence object contains the following information: 25 26 1. Latitude, longitude, and radius 27 2. Expiration time 28 3. Transition type 29 4.
