Hi All - I'm trying to use the "Generate Offline Map" sample and am running into an error that is telling me that the mobile map directory path is not specified.
I have tried hard coding the path in the sample to "c:\temp\out.mmpk" just in case my URL variable was not working correctly, but it still is giving me the same result. The only thing I have changed is to give it my own portal item which is a webmap that is available to the public for testing purposes.
I'm sure I'm missing something very simple as I'm new to Qt/QML. Any insights would be appreciated. Code is below, but it's almost identical to the original sample.
// Create a button and anchor it to the attribution top
QtControls.Button {
id: downloadButton
anchors {
horizontalCenter: parent.horizontalCenter
bottom: parent.verticalCenter
margins: 5 * scaleFactor
}
visible: map.loadStatus === Enums.LoadStatusLoaded
onClicked: extentRectangle.getRectangleEnvelope();
}
// Create an extent rectangle for selecting the offline area
Rectangle {
id: extentRectangle
anchors.centerIn: parent
width: parent.width - (50 * scaleFactor) height: parent.height - (125 * scaleFactor)
color: "transparent"
visible: map.loadStatus === Enums.LoadStatusLoaded
border {
color: "red"
width: 3 * scaleFactor
}
function getRectangleEnvelope() {
var corner1 = mapView.screenToLocation(extentRectangle.x, extentRectangle.y);
var corner2 = mapView.screenToLocation((extentRectangle.x + extentRectangle.width), (extentRectangle.y + extentRectangle.height));
var envBuilder = ArcGISRuntimeEnvironment.createObject("EnvelopeBuilder");
envBuilder.setCorners(corner1, corner2);
var mapExtent = GeometryEngine.project(envBuilder.geometry, SpatialReference.createWebMercator());
offlineMapTask.createDefaultGenerateOfflineMapParameters(mapExtent);
}
}
// Create Offline Map Task
OfflineMapTask {
id: offlineMapTask
portalItem: mapPortalItem
//onlineMap: map
property var generateJob
onErrorChanged: console.log("error:", error.message, error.additionalMessage);
onCreateDefaultGenerateOfflineMapParametersStatusChanged: {
if (createDefaultGenerateOfflineMapParametersStatus !== Enums.TaskStatusCompleted)
return;
// Take the map offline once the parameters are generated
takeMapOffline(offlineMapTask.createDefaultGenerateOfflineMapParametersResult);
}
function takeMapOffline(parameters) {
// create the job
generateJob = offlineMapTask.generateOfflineMap(parameters, "c:\temp\out.mmpk");
console.log(mapPortalItem.url);
console.log(mapPortalItem.itemId);
console.log(mapPortalItem.type);
