- * Outside state: We are 95% confident that the user is outside the geofence

- * The Unknown state is better explained with an example:
- *
- *                            __________
- *                           |         c|

- *                            """"""""""
- * In the diagram above, "a" and "b" are 2 geofences and "c" is the accuracy
- * circle reported by the GPS subsystem. Now with regard to "b", the system is
- * confident that the user is outside. But with regard to "a" is not confident
- * whether it is inside or outside the geofence. If the accuracy remains the
- * same for a sufficient period of time, the UNCERTAIN transition would be
- * triggered with the state set to Unknown. If the accuracy improves later, an
- * appropriate transition should be triggered.  This "sufficient period of time"
- * is defined by the parameter in the add_geofence_area API.
- *     In other words, Unknown state can be interpreted as a state in which the
- * GPS subsystem isn't confident enough that the user is either inside or
- * outside the Geofence. It moves to Unknown state only after the expiry of the
- * timeout.
- *
- * The geofence callback needs to be triggered for the ENTERED and EXITED
- * transitions, when the GPS system is confident that the user has entered
- * (Inside state) or exited (Outside state) the Geofence. An implementation
- * which uses a value of 95% as the confidence is recommended. The callback
- * should be triggered only for the transitions requested by the
- * add_geofence_area call.
- *
- * Even though the diagram and explanation talks about states and transitions,
- * the callee is only interested in the transistions. The states are mentioned
- * here for illustrative purposes.
- *
- * Startup Scenario: When the device boots up, if an application adds geofences,
- * and then we get an accurate GPS location fix, it needs to trigger the
- * appropriate (ENTERED or EXITED) transition for every Geofence it knows about.
- * By default, all the Geofences will be in the Unknown state.
- *
- * When the GPS system is unavailable, gps_geofence_status_callback should be
- * called to inform the upper layers of the same. Similarly, when it becomes
