[No issue] Info about show Instructions and Maneuvers

[moiatto]

Can you tell me how show instructions and maneuvers as standalone UI components?

Because I use the library for routing, not to show map. I have a valid DirectionsRoute and MapboxNavigation variables.

I don't think this library works standalone, or at least would quite some refactoring. I think it would be great if it would work independent from the map implementation, but this would quite some changes.

Understood

We use the the onMilestoneEvent in the Kurviger App, there is an arrival milestone, milestones are triggered for Banner Instructions (IIRC).

I tried a lot but without success.

Can you tell me what's wrong?

// Custom Milestone for DESTINATION
navigation.addMilestone(new RouteMilestone.Builder()
        .setIdentifier(1002)
        .setInstruction(new Instruction() {
                            @Override
                            public String buildInstruction(RouteProgress routeProgress) {
                                return "Destination";
                            }
                        })
        .setTrigger(Trigger.all(
                            Trigger.eq(TriggerProperty.LAST_LEG, TriggerProperty.TRUE),
                            Trigger.eq(TriggerProperty.LAST_STEP, TriggerProperty.TRUE)
                    ))
        .build());

// Custom Milestone for WAYPOINT
navigation.addMilestone(new StepMilestone.Builder()
        .setIdentifier(1001)
        .setInstruction(new Instruction() {
                          @Override
                          public String buildInstruction(RouteProgress routeProgress) {
                              return "Waypoint";
                          }
                      })
        .setTrigger(Trigger.all(
                            Trigger.eq(TriggerProperty.LAST_LEG, TriggerProperty.FALSE),
                            Trigger.eq(TriggerProperty.LAST_STEP, TriggerProperty.TRUE)
                    ))
        .build());

About Trigger.eq(TriggerProperty.LAST_STEP, TriggerProperty.TRUE) can you tell me why in TriggerProperty.java:

statementObjects.put(TriggerProperty.LAST_STEP,
  new Number[] {routeProgress.currentLegProgress().stepIndex(),
    (routeProgress.currentLeg().steps().size() - 2)});

(routeProgress.currentLeg().steps().size() - 2) I don't understand -2 ?
