En esta sección, se documenta cómo establecer el destino del vehículo después de que el servidor hace coincidir un viaje con un vehículo.

Cómo establecer el destino en la app del conductor
Después de vincular un consumidor con un conductor, debes configurar el destino del viaje en la app del conductor. Para ello, sigue estos pasos:
Recupera el destino del vehículo de su colección de puntos de referencia en Fleet Engine, que muestran
GetTrip()
,UpdateTrip()
yGetVehicle()
.Para establecer el destino, llama al método
setDestination()
del SDK de Navigation para Android.
En los siguientes ejemplos, se muestra cómo establecer el destino en la app del conductor.
Java
private void navigateToLocation(LatLng locationLatLng, RoutingOptions routingOptions) {
Waypoint destination = Waypoint.newBuilder().setLocation(locationLatLng).build();
// Create a future to await the result of the asynchronous navigator task.
ListenableResultFuture<Navigator.RouteStatus> pendingRoute =
mNavigator.setDestination(destination, travelMode);
// Define the action to perform when the SDK has determined the route.
pendingRoute.setOnResultListener(
new ListenableResultFuture.OnResultListener<Navigator.RouteStatus>() {
@Override
public void onResult(Navigator.RouteStatus code) {
switch (code) {
case OK:
// Hide the toolbar to maximize the navigation UI.
if (getActionBar() != null) {
getActionBar().hide();
}
// Enable voice audio guidance (through the device speaker).
mNavigator.setAudioGuidance(
Navigator.AudioGuidance.VOICE_ALERTS_AND_GUIDANCE);
// Simulate vehicle progress along the route for demo/debug builds.
if (BuildConfig.DEBUG) {
mNavigator.getSimulator().simulateLocationsAlongExistingRoute(
new SimulationOptions().speedMultiplier(5));
}
// Start turn-by-turn guidance along the current route.
mNavigator.startGuidance();
break;
// Handle error conditions returned by the navigator.
case NO_ROUTE_FOUND:
displayMessage("Error starting navigation: No route found.");
break;
case NETWORK_ERROR:
displayMessage("Error starting navigation: Network error.");
break;
case ROUTE_CANCELED:
displayMessage("Error starting navigation: Route canceled.");
break;
default:
displayMessage("Error starting navigation: "
+ String.valueOf(code));
}
}
});
}
Kotlin
private fun navigateToLocation(locationLatLng: LatLng, travelMode: RoutingOptions) {
val destination = Waypoint.newBuilder().setLocation(locationLatLng).build()
// Create a future to await the result of the asynchronous navigator task.
val pendingRoute = mNavigator.setDestination(destination, travelMode)
// Define the action to perform when the SDK has determined the route.
pendingRoute.setOnResultListener(
object : ListenableResultFuture.OnResultListener<Navigator.RouteStatus>() {
override fun onResult(code: Navigator.RouteStatus) {
when (code) {
Navigator.RouteStatus.OK -> {
// Hide the toolbar to maximize the navigation UI.
getActionBar()?.hide()
// Enable voice audio guidance (through the device speaker).
mNavigator.setAudioGuidance(Navigator.AudioGuidance.VOICE_ALERTS_AND_GUIDANCE)
// Simulate vehicle progress along the route for demo/debug builds.
if (BuildConfig.DEBUG) {
mNavigator
.getSimulator()
.simulateLocationsAlongExistingRoute(SimulationOptions().speedMultiplier(5))
}
// Start turn-by-turn guidance along the current route.
mNavigator.startGuidance()
