1*d353a188SXin Li 2*d353a188SXin LiAndroid Geofencing Sample 3*d353a188SXin Li=================================== 4*d353a188SXin Li 5*d353a188SXin LiWhen the user enters the vicinity of the Android building (B44) or the Yerba Buena 6*d353a188SXin LiGardens near the Moscone center in San Francisco, a notification silently appears on their 7*d353a188SXin Liwearable with an option to check in. This notification automatically disappears when they leave 8*d353a188SXin Lithe area, and reappears the next time they are at one of these locations. 9*d353a188SXin Li 10*d353a188SXin LiIntroduction 11*d353a188SXin Li------------ 12*d353a188SXin Li 13*d353a188SXin LiGeofencing combines awareness of the user's current location with awareness of 14*d353a188SXin Linearby features, defined as the user's proximity to locations that may be of 15*d353a188SXin Liinterest. To mark a location of interest, you specify its latitude and longitude. 16*d353a188SXin LiTo adjust the proximity for the location, you add a radius. The latitude, 17*d353a188SXin Lilongitude, and radius define a geofence. You can have multiple active 18*d353a188SXin Ligeofences at one time. 19*d353a188SXin Li 20*d353a188SXin LiTo use geofencing, start by defining the geofences you want to monitor. 21*d353a188SXin LiAlthough you usually store geofence data in a local database or download 22*d353a188SXin Liit from the network, you need to send a geofence to Location Services as 23*d353a188SXin Lian instance of [Geofence][2], which you create with `Geofence.Builder`. Each 24*d353a188SXin LiGeofence object contains the following information: 25*d353a188SXin Li 26*d353a188SXin Li1. Latitude, longitude, and radius 27*d353a188SXin Li2. Expiration time 28*d353a188SXin Li3. Transition type 29*d353a188SXin Li4.
