+ * <p> Inside state: The hardware subsystem is reasonably confident that the user is inside

+ * is outside the geofence Unknown state: Unknown state can be interpreted as a state in which the

+ * outside the Geofence. If the accuracy does not improve for a sufficient period of time,
+ * the {@link #GEOFENCE_UNCERTAIN} transition would be triggered. If the accuracy improves later,
