Constants
public static final int GEOFENCE_TRANSITION_DWELL
The transition type indicating that the user enters and dwells in geofences for a
given period of time. If
GEOFENCE_TRANSITION_ENTER
is also specified, this alert will always be sent
after the
GEOFENCE_TRANSITION_ENTER
alert.
You must set the duration of loitering before this alert is sent using
Geofence.Builder.setLoiteringDelay(int)
.
public static final int GEOFENCE_TRANSITION_ENTER
The transition type indicating that the user enters the geofence(s).
public static final int GEOFENCE_TRANSITION_EXIT
The transition type indicating that the user exits the geofence(s).
public static final long NEVER_EXPIRE
Expiration value that indicates the geofence should never expire.
Public Methods
public abstract String getRequestId ()
