LocalTileLayer not loading when running through the Player

G-Palmer — Mon, 18 Apr 2016 21:11:01 GMT

I have created an offline application which uses the ArcGISLocalTileLayer function to display the map. The app loads fully when testing through the Qt Creator but the map doesn't appear when the app's loaded through the Player. Is there anything that I can do to the code to fix this?

What does your path look like for referencing the local tiled layer?

Here's the code for the section that holds the tiled layer components

App {
    id: app
    width: 1220
    height: 880
    property color penColor: colorDialog.color;
    property int penWidth;
    Rectangle {...}
    Map {
        id: map
        anchors {...}
        rotationByPinchingEnabled: true
        zoomByPinchingEnabled: true
      positionDisplay {
            positionSource: PositionSource {
            }
        }
        ArcGISLocalTiledLayer {
            id:aerials
            path: "WairarapaImagery.tpk"
        }
        ArcGISLocalTiledLayer {
            id: vector
            path: "WairarapaVector.tpk"
        }
     ...
    }

You will need to specify the path to these TPKs. In the case of AppStudio, a good cross platform method is to use is the AppFramework.userHomePath property. This will return to you the "user home" location on each device. In the case of iOS, that would be <application_bundle>/Documents. So, in your code, you could say "path: AppFramework.userHomePath + "/WairarapaImagery.tpk", and then make sure to transfer your TPK to that location on your device (usually via iTunes).

I tried adding in the userHomePath but the AppStudio player is still not able to display the imagery.

And the TPK is copied onto the device into that specified location? If not, please use iTunes to transfer the TPK from your desktop onto your device. If you have already done this, then it may be worth posting your question in the AppStudio space. Someone using AppStudio may be able to give you pointers on using the Player app with local offline data.

Make sure to create a data folder in your app directory. Add the tpk to the data folder. I have tested this sample code and it works on both android and iPad. Can you please test it by uploading this sample and test it in the player?

property string outputTPK: dataPath + "/" + inputTPK

function copyLocalData(input, output) {

var resourceFolder = AppFramework.fileFolder(app.folder.folder("Data").path);

AppFramework.userHomeFolder.makePath(dataPath);

resourceFolder.copyFile(input, output);

return output
