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