Description

I'm trying to write data per QSettings on Android using an URL from a file dialog. The file is created but no content written. Seems the content:// conversion is not working properly, I see multiple files being created in the file dialog of my program after pressing Save (attachment) but only one in the file explorer app.

Not sure if this warning helps:

W ParcelFileDescriptor: Peer expected signal when closed; unable to deliver after detach

Some simplified code:

import QtQuick
import QtQuick.Controls
import QtQuick.Dialogs
import Qt.labs.platform
import Qt.labs.settings

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    FileDialog {
        id: fileDialog
        folder: StandardPaths.writableLocation(StandardPaths.DocumentsLocation)
        onAccepted: {
            mySettings.fileName = file
            mySettings.setValue("test",true)
        }
    }

    Settings {
        id: mySettings
    }

    Button {
        id: btnClose
        text: "Click me"
        onClicked: {
            fileDialog.acceptLabel = qsTr("Save")
            fileDialog.fileMode = FileDialog.SaveFile
            fileDialog.title = qsTr("Save configuration")
            fileDialog.open()
        }
    }

}

The actual code runs on Qt with

    QSettings settings(fileName, QSettings::IniFormat);
    qDebug() << settings.fileName() << settings.status();
//returns some content:// url and NoError
    settings.beginGroup("config");
    for (auto i = configData.begin(); i!=configData.end(); i++)
        settings.setValue(i.key(), i.value());
    settings.endGroup();
    qDebug() << settings.status(); 
//still NoError
