TestNavigationManager

fun clearNavigationManagerCallback(): Unit

Clears the callback for receiving navigation manager events.

fun getNavigationEndedCount(): Int

Returns the number of times that navigation was ended via navigationEnded since creation or the last call to reset.

fun getNavigationManagerCallback(): NavigationManagerCallback?

Returns the callback set via setNavigationManagerCallback.

The listener will be null if one was never set, or if clearNavigationManagerCallback or reset was called.

fun getNavigationStartedCount(): Int

Returns the number of times that navigation was started via navigationStarted since creation or the last call to reset.

fun getTripsSent(): (Mutable)List<Trip!>

Returns all the Trips sent via updateTrip.

The trips are stored in the order in which they were sent, where the first trip in the list, is the first trip sent.

The trips will be stored until reset is called.

fun navigationEnded(): Unit

Notifies the host that the app has ended active navigation.

Only one app may be actively navigating in the car at any time and ownership is managed by the host. The app must call this method to inform the system that it has ended navigation, for example, in response to the user cancelling navigation or upon reaching the destination.

This method is idempotent.

fun navigationStarted(): Unit

Notifies the host that the app has started active navigation.

Only one app may be actively navigating in the car at any time and ownership is managed by the host. The app must call this method to inform the system that it has started navigation in response to user action.

This function can only called if setNavigationManagerCallback has been called with a non-null value. The callback is required so that a signal to stop navigation from the host can be handled using onStopNavigation.

This method is idempotent.

fun reset(): Unit

Resets the values tracked by this TestNavigationManager.

fun setNavigationManagerCallback(
    executor: Executor,
    callback: NavigationManagerCallback
): Unit

Sets a callback to start receiving navigation manager events.

fun updateTrip(trip: Trip): Unit

Sends the destinations, steps, and trip estimates to the host.

The data may be rendered at different places in the car such as the instrument cluster screen or the heads-up display.

This method should only be invoked once the navigation app has called navigationStarted, or else the updates will be dropped by the host. Once the app has called navigationEnded or received onStopNavigation it should stop sending updates.

As the location changes, and in accordance with speed and rounded distance changes, the TravelEstimates in the provided Trip should be rebuilt and this method called again. For example, when the next step is greater than 10 kilometers away and the display unit is kilometers, updates should occur roughly every kilometer.

Data provided to the cluster display depends on the vehicle capabilities. In some instances the information may not be shown at all. On some vehicles s of unknown type may be skipped while on other displays the associated icon may be shown.
