How do I load offline TPK?

Question

Hi there

I created a small TPK using the Tile Package Kreator. I then downloaded the AppStudio Tiled Layer sample app and tried to load my offline TPK - but I was unable to do so, not sure how to load it as sample shows how to load an online TPK.

The specific code to load URL was written as:

Map {

id: map

Basemap {

// Nest an ArcGISVectorTiledLayer Layer in the Basemap

ArcGISVectorTiledLayer {

url: "http://www.arcgis.com/home/item.html?id=dcbbba0edf094eaa81af19298b9c6247"

}

How would I change this to reference a TPK stored locally? The TPK will for now reside in the app's Data folder. Ideally I would like a user to browse to a folder where the TPK is stored but I wont try and attempt to do so now.

Thank you.

Regards

Mervyn

How can you load a TPK from a button or drop box.... I initially load a TPK file into my app as seen above in this post. But I want a button to change that to a different tpk on the device....How do I do this... I tried this and nothing...errors.... // SNIP INSIDE BUTTON CLICK var layer = ArcGISRuntimeEnvironment.createObject("ArcGISTiledLayer"); layer.url = AppFramework.userHomeFolder.filePath("ArcGIS/AppStudio/Data/QuickReport/backgrounddatatpk.tpk"); mapView.map = layer;‍‍‍ // SNIP END OF BUTTON ON CLICK EVENT‍‍‍‍‍‍‍

Hi Nakul

Thank you for responding. I have tried this approach but my offline TPK does not load - it does not even give me the grid view with the Esri licence statement that I get when the online map loads.

I then added a property statement for the data path but this did not help. Could you please look at the below code and suggest where I may be going wrong?

import QtQuick 2.7

import QtQuick.Controls 2.1

import QtQuick.Controls.Styles 1.4

import QtQuick.Controls.Material 2.1

import ArcGIS.AppFramework 1.0

import ArcGIS.AppFramework.Controls 1.0

import Esri.ArcGISRuntime 100.1

App {

id: app

width: 414

height: 736

property real scaleFactor: AppFramework.displayScaleFactor

property string dataPath:  AppFramework.userHomeFolder.filePath("ArcGIS/AppStudio/Data")

// Create MapView that contains a Map

MapView {

id: mapView

anchors.fill: parent

Map {

id: map

Basemap {

ArcGISTiledLayer {

TileCache {

path: dataPath + "hoekwil.tpk"

}

initialViewpoint: ViewpointCenter {

center: Point { x:22.6; y: -33.9; spatialReference: SpatialReference { wkid: 4326 } }

targetScale: 50000

}

// Busy Indicator

BusyIndicator {

anchors.centerIn: parent

height: 48 * scaleFactor

width: height

running: true

Material.accent:"#8f499c"

visible: (mapView.drawStatus === Enums.DrawStatusInProgress)

}

Thank you.
