Path for SD Card.

Hi All,

I am developing an app, which i have to access the .mmpk [map package file]. MMPK file will be copied in the SD card root.

Query 1:
What will be the path to set it in the QML Code?

Query 2:
If the .mmpk file is added in the /Resources [Resources/Resources.qrc/resources [where the AppIcon is present]], So the .mmpk will be bundles and go along with the .apk file.
Is it the right way? if it so, How to set the path?

Tried:

property real scaleFactor: System.displayScaleFactor
//Input Path
//property string strMmpkdataPath: System.userHomePath + "/ArcGIS/Runtime/Data/mmpk/" //System path

//property string strMmpkdataPath: ":/Resources/CARCommune.mmpk" //Mobile SD Card Path

//property string strMmpkdataPath: "../Resources/CARCommune.mmpk" //Mobile SD Card Path

property string strMmpkdataPath: "qrc:/Resources/CARCommune.mmpk" ////Mobile SD Card URL

//System.userHomePath = C:\Users\mmanohar

//OutPut Path
property string runtimePath: System.userHomeFolder.filePath("/ArcGIS/Runtime") //mobilePath

property string dataPath: runtimePath + "/Data"

property string InputMMPK: "CARCommune.mmpk"

A qrc URL is not some path on the SD card, it is a program internal file-like data store.

I.e. Qt Resources builds files into the executable, they are then part of the program.
They can be treated like read-only files from within the program but don't exist outside the program.

Cheers,

Hi Anda_skoa,

Thanks for the reply. I don't want my maps stored in Qrc.

Scenario:
Maps will be copied to SD Card manually, The qt application will display the map from the SD Card.
In this case how to set the SD card Path.

Code snippets what I tried according to ESRI ArcGIS Runtime SDK for Qt 100.0.0:

Code:

---

import QtQuick 2.6
import Esri.ArcGISRuntime 100.0
import Esri.ArcGISExtras 1.1
 
Rectangle {
    width: 800
    height: 600
 
    property real scaleFactor: System.displayScaleFactor
 //   property string dataPath: System.userHomePath + "/ArcGIS/Runtime/Data/mmpk/"
       [B][I]property string dataPath: "file:///storage/sdcard1/"[/I][/B]
 
    // Create MapView
    MapView {
        id: mapView
        anchors.fill: parent
    }
 
    // Create a Mobile Map Package and set the path
    MobileMapPackage {
        id: mmpk
        path: dataPath + "Yellowstone.mmpk"
 
        // load the mobile map package
        Component.onCompleted: {
            mmpk.load();
        }
 
        // wait for the mobile map package to load
        onLoadStatusChanged: {
            if (loadStatus === Enums.LoadStatusLoaded) {
                // set the map view's map to the first map in the mobile map package
                mapView.map = mmpk.maps[0];
            }
        }
    }
 
    Rectangle {
        anchors.fill: parent
        color: "transparent"
        border {
            width: 0.5 * scaleFactor
            color: "black"
        }
    }
}

ok, your initial posting had conflicting information that.

If the maps are copied manually, wouldn't the path be manually chosen?
I.e. wouldn't you need a directory selector/picker to get it from the user?

If the path is a standard system path, have you checked if any of the locations of QStandardPath points to it?
