Mapview Error: Not Enough Arguments Error

Former Member over 4 years ago

I have tried using the example provided in the Garmin developper page https://developer.garmin.com/connect-iq/connect-iq-faq/how-do-i-use-a-mapview/ but unfortunately, I received the folllowing errors :

Encountered app crash

Error: Not enough Arguments Error

Details: Failed invoking <symbol>

Stack:

- Initialize()

- getInitialView()

The functions are as follows:

var mView;

function initialize(view) { (This line showing the error)

BehaviorDelegate.initialize();

mView = view;

}

// Return the initial view of your application here

function getInitialView() as Array<Views or InputDelegates>? {

return [ new MapsView(), new MapsDelegate() ] as Array<Views or InputDelegates>; (This line showing error)

}

Can someone help me with this?

I don't see where you are passing "view" here. If that's in the delegate, you need to do something like

function getInitialView() as Array<Views…

for the 4.1.2 sdk on windows, there is a samples directory in the root of the sdk

Hi, I've never used Mapview,

but what I can see is your initilialize function wait for argument which you don't provide in your getInitialView.

        return [theView,new MapsDelegate(theView)];
    }

You also want to look at the MapSample in the SDK. A coule of notes, is MapView and MapTrackView only work on devices with on board maps. Thje sim doesn't work quite the same as a real device, where things like the scale isn't shown in the sim, and with MapTrackview (and GPS on), the track is shown for you - you don't have to do a thing.

For devices with maps, here's an app that uses MapTrackView:

Here's a simple one that uses MapView:

Thank you for your reply! It seemed to work but I have this error now.

// on enter button press chenage the map view to browse mode

mView.setMapMode(WatchUi.MAP_MODE_BROWSE); (This line shows the error)

return true;

}

Thank you for the examples but I would like to look at the source code as I would like to add more functions to the application. Where would I be able to take a look at the MapSample in the SDK?
