Public Methods

public abstract void addArrivalListener (Navigator.ArrivalListener listener)

Registers a listener for arrival events.

Note: In order to avoid memory leaks, use removeArrivalListener(ArrivalListener) to remove the listener that is no longer required.

Parameters

listener	the listener to register. Must not be `null`.

Throws

NullPointerException	if the listener is `null`.

public abstract void addNavigationSessionListener (Navigator.NavigationSessionListener listener)

Registers a listener for new navigation sessions.

Note: In order to avoid memory leaks, use removeNavigationSessionListener(NavigationSessionListener) to remove the listener that is no longer required.

Parameters

listener	the listener to register. Must not be `null`.

Throws

NullPointerException	if the listener is `null`.

public abstract void addRemainingTimeOrDistanceChangedListener (int timeChangeThresholdSeconds, int distanceChangeThresholdMeters, Navigator.RemainingTimeOrDistanceChangedListener listener)

Registers a listener for when the remaining time or distance to the destination changes by more than a specified threshold.

The listener could be called as a result of (for example) user movement, a change in traffic conditions OR a change in route OR a change in destination, or when the remaining time and distance first become known.

Note: In order to avoid memory leaks, use removeRemainingTimeOrDistanceChangedListener(RemainingTimeOrDistanceChangedListener) to remove the listener that is no longer required.

Note: Same listener instance can be added with different threshold values however, calling removeRemainingTimeOrDistanceChangedListener(RemainingTimeOrDistanceChangedListener) using that particular instance will remove it altogether.

Parameters

timeChangeThresholdSeconds	If the absolute change in the remaining time to destination in seconds is greater than or equal to this value, then the listener is called. This threshold must not be negative.
distanceChangeThresholdMeters	If the absolute change in the remaining distance in meters is greater than or equal to this value, then the listener is called. This threshold must not be negative.
listener	the listener to register. Must not be `null`.

Throws

IllegalArgumentException	if timeChangeThresholdSeconds is negative, or distanceChangeThresholdMeters is negative.
NullPointerException	if the listener is `null`.

public abstract void addReroutingListener (Navigator.ReroutingListener listener)

Registers a listener for route change that is requested in response to vehicle going off the suggested route.

Note: In order to avoid memory leaks, use removeReroutingListener(ReroutingListener) to remove the listener that is no longer required.

Parameters

listener	the listener to register. Must not be `null`.

Throws

NullPointerException	if the listener is `null`.

public abstract void addRouteChangedListener (Navigator.RouteChangedListener listener)

Registers a listener for route changed events.

Note: In order to avoid memory leaks, use removeRouteChangedListener(RouteChangedListener) to remove the listener that is no longer required.

Parameters

listener	the listener to register. Must not be `null`.

Throws

NullPointerException	if the listener is `null`.

public abstract void addTrafficUpdatedListener (Navigator.TrafficUpdatedListener listener)

Registers a listener for traffic update events.

Note: In order to avoid memory leaks, use removeTrafficUpdatedListener(TrafficUpdatedListener) to remove the listener that is no longer required.

Parameters

listener	the listener to register. Must not be `null`.

Throws

NullPointerException	if the listener is `null`.

public abstract void cleanup ()

Cleans up internal state of the Navigator.

Invoke this method at the end of the user's session, usually in Activity or Fragment onDestroy() (i.e. when you no longer need a Navigator).

Note: calling this method will cancel any pending requests to setDestinations(List).

public abstract void clearDestinations ()

Clears all previously set destinations and removes any calculated routes from the map. If navigation is running, this will automatically stop it.

public abstract void clearLicensePlateRestrictionInfo ()

Clears license plate information about the current driver. This will only apply to setDestination calls made after this value is set.

public abstract Waypoint continueToNextDestination ()

Removes the current destination. Following this call, guidance will be toward the next destination, and information about the old destination is not available.

Returns

the waypoint guidance is now heading to, or null if there were no more waypoints left

public abstract ListenableResultFuture<RouteInfo> fetchRouteInfo (Waypoint waypoint, RoutingOptions routingOptions)

This method is deprecated.
Prior to being deprecated, this method was only available to Mobility Services customers. Please use the computeCustomRoutes method on the Routes Preferred API instead.

Returns route information for routes based on each value of ERROR(/RoutingStrategy). ERROR(/RoutingStrategy) is ignored since this method returns the route information for all routing strategies.

Note: This is recalculated on every call and may not match the routes currently being used by navigation since traffic and other factors may have been updated in the interim.

Parameters

waypoint	the destination waypoint for the route
routingOptions	the options used to fetch the route info

Returns

the returned future

public abstract RouteSegment getCurrentRouteSegment ()

Returns the current segment of the journey. This RouteSegment will have its starting position as the most recent known (road-snapped) position of the device.

Returns

a route segment object, or null if there is no current route

public abstract TimeAndDistance getCurrentTimeAndDistance ()

Returns the estimated time and distance from the current position to the current destination.

Returns

a time and distance object, or null if there is no current route

public abstract List<RouteSegment> getRouteSegments ()

Returns a list of route segments. The destination of each returned segment will correspond to a destination set by setDestination(s).

public abstract Simulator getSimulator ()

Returns a Simulator object, for use during testing.

public abstract List<TimeAndDistance> getTimeAndDistanceList ()

Returns a list of times and distances corresponding to each destination in the current route, representing the estimated time and distance from the current position to each destination.

public abstract List<LatLng> getTraveledRoute ()

Returns the route traveled so far during this guidance session (since the last call to startGuidance()).

The route consists of road-snapped locations returned by the RoadSnappedLocationProvider, and simplified to produce line segments.

Note: The system polls the client for GPS signals to obtain location data. Poor GPS signal can result in further interpolation, which might produce less precise routes.

public abstract boolean isGuidanceRunning ()

Returns true if guidance is currently running. Note that guidance will only run once a route to a destination has been computed and startGuidance() has been called.

public abstract boolean registerServiceForNavUpdates (String packageName, String serviceName, NavigationUpdatesOptions options)

Registers a service to receive navigation updates. Navigation updates are sent to the service once per second.

The receiving service should have a Messenger whose binder is exposed in the Service.onBind(Intent) method. Create a Handler for the messenger to receive messages containing turn-by-turn navigation information after the service is registered. Messages sent from the Navigation SDK have the message code in Message.what set to ERROR(/TurnByTurnManager#MSG_NAV_INFO). The handler can then use ERROR(/TurnByTurnManager#readNavInfoFromBundle(Bundle bundle)) to get the ERROR(/NavInfo) from the message data, which can be retrieved from the message using ERROR(/Message#getData())).

THIS API IS A PREVIEW RELEASE.
IT IS SUBJECT TO CHANGE AND BACKWARD COMPATIBILITY IS NOT GUARANTEED

Parameters

packageName	the name of the package where the service is defined.
serviceName	the name of the service.
options	the options that will be used when reporting navigation updates to a registered service.

Returns

true if the service was successfully registered; false if the service was not successfully registered or if there is already a service registered.

Throws

SecurityException	if the caller does not have permission to access the service or the service cannot be found.

public abstract boolean registerServiceForNavUpdates (String packageName, String serviceName, int numNextStepsToPreview)

Registers a service to receive navigation updates. Navigation updates will be sent to the service once per second.

The receiving service should have a Messenger whose binder is exposed in the Service.onBind(Intent) method. Create a Handler for the messenger to receive messages containing turn-by-turn navigation information once the service is registered. Messages sent from the Navigation SDK have the message code in Message.what set to ERROR(/TurnByTurnManager#MSG_NAV_INFO). The handler can then use ERROR(/TurnByTurnManager#readNavInfoFromBundle(Bundle bundle)) to get the ERROR(/NavInfo) from the message data, which can be retrieved from the message using ERROR(/Message#getData())).

Sets license plate information about the current driver. This allows us to route around certain types of road restrictions which are based on license plate number. This will only apply to setDestination calls made after this value is set. Ideally you'd call this immediately after getting the navigator.

Parameters

rawLicensePlateLastDigit	The last digit of the license plate (must be between 0 and 9).
licensePlateCountryCode	Currently we support Indonesia (ID) and Brazil (BZ) others may be supported in the future and you are free to proactively provide this information.

public abstract void setSpeedAlertOptions (SpeedAlertOptions speedAlertOptions)

Sets SpeedAlertOptions for customizing the triggering thresholds for SpeedAlertSeveritys.

You can use this method to customize the speed alert triggering thresholds in percentage for both SpeedAlertSeverity.MINOR and SpeedAlertSeverity.MAJOR alerts. You can also use this method to configure the time in seconds needed to upgrade speed alerts from SpeedAlertSeverity.MINOR to SpeedAlertSeverity.MAJOR.

By setting a null SpeedAlertOptions or not setting any, you won't receive any speeding feed data, and the NavSDK's default speed alert will display: speed alert shows red text in white/dark background for day/night mode respectively when the speed is less than 5 mph or 10 kph over the speed limit, and shows white text in red background when speeding more than 5 mph or 10 kph.

The triggering thresholds configured in SpeedAlertOptions are used to decide whether to display minor or major alerts.

Parameters

speedAlertOptions

public abstract void setSpeedingListener (SpeedingListener speedingListener)

Registers a SpeedingListener for the percentage above the speed limit the driver is currently driving at.

By setting a null SpeedingListener or not setting any, you won't receive any speeding feed data.

Parameters

speedingListener

public abstract void setTaskRemovedBehavior (int taskRemovedBehavior)

Sets how the background service reacts when a user removes this app from their device's recent screen. This impacts location updates, continued navigation/guidance, and the associated notification.

By default, the service, guidance, and notification will continue to perform after the app/task is removed, equivalent to Navigator.TaskRemovedBehavior.CONTINUE_SERVICE.

Parameters

taskRemovedBehavior	The TaskRemovedBehavior value for desired behavior.

public abstract void setTransactionIds (List<String> transactionIds)

Sets the ongoing transaction IDs. This API should be used when a new navigation session starts (in the Navigator.NavigationSessionListener.onNewNavigationSession()) and when the transaction IDs change in an ongoing navigation session (e.g. when the list of journey segments is updated).

The transactionIds parameter should be populated with unique string identifiers for one or more transactions that apply to the following events during the current navigation.

This will overwrite any transaction IDs set before.

Transaction IDs will be cleared at the end of the navigation session.

Each transaction ID must be at least 1 and at most 64 characters long, and there is a maximum of 100 transaction IDs per call.

This method should only be used by Mobility Services customers.

Parameters

transactionIds	one or more transaction IDs to which the following navigation applies. A transaction ID is an arbitrary string that is unique for each billable transaction.

Throws

NavigationTransactionRecorder.TransactionException	occurs for the following issues with transaction IDs: null transaction IDs, greater than `MAX_NUM_TRANSACTION_IDS` of transaction IDs, or transactions IDs longer than `MAX_TRANSACTION_ID_LENGTH`.

public abstract void startGuidance ()

If a destination has been set and a route computed for it, starts turn-by-turn navigation guidance for the route. If a route has not yet been computed, turn-by-turn guidance will start once it has.

You must explicitly call stopGuidance() to stop the navigation service. The navigation service will not automatically stop upon arrival. If you want to stop the navigation service upon arrival, you need to call stopGuidance() in the NavArrivalListener.

Note: this method does not change the position of the camera.

public abstract void stopGuidance ()

Stops turn-by-turn navigation guidance.

public abstract boolean unregisterServiceForNavUpdates ()

Unregisters the service that was previously registered via registerServiceForNavUpdates(String, String, int).

THIS API IS A BETA RELEASE.
IT IS SUBJECT TO CHANGE AND BACKWARDS COMPATIBILITY IS NOT GUARANTEED

Returns

true if the service was successfully unregistered; false if the service was not successfully unregistered or if there is not a previously registered service.
