SKRoutingErrorCodeRouteCannotBeCalculated error

[benhyfn]

Often when trying to route trips with long distances we receive this error. Upon adding some retry logic, we found that the same exact trip can be calculated after numerous attempts (4 or 5).

One such trip was from San Francisco, CA to Houston, CO. After 5 attempts with the same route, we finally were able to receive a successful route from SKRoutingService.

Can you explain why this might be happening?

We've just tested using the latest Android 3.0 and everything is working as expected (tested the routing an navigation menu entry and the navigation UI menu entry)
Is this case reproducing in the demo app? Can you please send us a video and the setting that you're using?

FYI, I'm speaking about the iOS SDK. I don't know if the same issue exists on the Android SDK. But the issue we're seeing is that it is not repeatable. Sometimes long trips will calculate, others will not. In the case of an error, we always get this generic SKRoutingErrorCodeRouteCannotBeCalculated error. The next time I see the issue I'll post a video.

I am able to reproduce this fairly regularly. See the video here:
https://dl.dropboxusercontent.com/u/...ScreenFlow.mp4

These are the points of the trip that resulted in error, and eventually worked when retried:

(Place: name: Current Location [37.7874, -122.408])
(Place: name: Newark [33.3055, -111.948])
(Place: name: Dropped Pin [33.5447, -101.911])
(Place: name: Dropped Pin [40.5033, -115.535])
(Place: name: Disneyland Rd [43.273, -108.679])

Any update on this?

Unfortunately, we cannot reproduce this issue with the latest traffic 3.0 build. We used to have this issue with long routes on fresh install, but this is fixed now.
We've modified our demo project to calculate a route at every button press and add a new via point every time. This worked even at fresh install. The video with the fresh install can be found here https://www.dropbox.com/s/vb383xa0gd...oints.mov?dl=0.

Can you please reproduce this issue in our demo project? or at least give us more details about the environment they're using.

I'm still seeing this fairly regularly. Here's a log from a recent case this morning:

All I did was keep retrying and then the route was calculated. For what it's worth, the start & destination are very close to each other, and the viaPoint is 7 hours away.

We'll investigate this further.

[Adela_Silvia]

We still cannot reproduce this issue.
Using the code snippet below (same coordinates) we always get a successfully calculated route, even at fresh install. Please try to reproduce this in our demo project to see if there might be a problem in the way you're using our SDK:
Add this to the MapDisplayIBViewController, viewDidLoad method:

[SKRoutingService sharedInstance].routingDelegate = self;
[SKRoutingService sharedInstance].mapView = self.mapView;

SKRouteSettings *route = [SKRouteSettings routeSettings];
route.startCoordinate = CLLocationCoordinate2DMake(33.8552, -118.316);
route.destinationCoordinate = CLLocationCoordinate2DMake(33.8318, -118.298);
route.useLiveTraffic = YES;
route.waitForCorridorDownload = YES;

SKViaPoint *viaPoint = [SKViaPoint viaPoint:0 withCoordinate:CLLocationCoordinate2DMake(37.7891, -122.408)];
route.viaPoints = @[viaPoint];

[[SKRoutingService sharedInstance] calculateRoute:route];
