Error reading local XML file with XmlListModel

[KeineAhnung]

Hi,

I am still trying to port my Sailfish App to Android. So far I managed to download a XML file from the web and to store it locally. Using my C++ file handler I am able to read the file but I get an "unknown error" when I try to read the XML file with XmlListModel.

Here is my Code:

import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.4
import QtQuick.Layouts 1.1
import QtQuick.XmlListModel 2.0

    toolBar: ToolBar {
        RowLayout {
            ToolButton {
                text: "Back"
                visible: stack.depth > 1
 
                onClicked: stack.pop()
            }
        }
    }
 
    XmlFileHandler {

        property bool showEventDates: false
        property int offset: 0
        property string actionItem: ""
        property string baItem: ""
        property string hvoItem: ""
 
        onNextEventsArrayChanged: {
            if(fileStat > 0){
                for (var i = 0; i < nextEventsArray.length; i++){
                    console.log(i+": "+nextEventsArray[i])
                }
                if(showInternalDates)
                    offset = nextEventsArray[24]
 
                actionItem = "am: "+handler.nextEventsArray[20]+" Uhr\n"+handler.nextEventsArray[22]

The path is correct and pointing to the right file. I use the same code on Sailfish and there it is working. Where could I look for my error?

[sedi]

Have you looked for character encoding differences? That can sometimes be a PITA when working cross-platform.

[KeineAhnung]

That is a good hint but I do not believe so. The path it not hardcoded, I get it via my c++ class:

fileLocation = QDir(QStandardPaths::writableLocation(QStandardPaths::DataLocation));

fileLocation = QDir(QStandardPaths::writableLocation(QStandardPaths::DataLocation));

[anda_skoa]

Have you tried returning a file URI? I.e. QUrl::fromLocalFile().

Cheers,

[KeineAhnung]

Thanks for the hint, I got it working.

Initially I returned the fileLocation as QString resulting in qrc:/Users/*/Library/Application Support/[AppName]/*.xml
If I return the path via fromLocalFile()

return QUrl::fromLocalFile(fileUrl);

return QUrl::fromLocalFile(fileUrl);

To copy to clipboard, switch view to plain text mode 

it results in file:///Users/*/Library/Application Support/[AppName]/*.xml
and that path works OS X and Android.
