Выберите файл в Android с QML FileC ⇐ Android

[Anonymous]

В моем приложении QML я хочу выбрать файл с FileDialog в QML: < /p>
FileOpen {
id: fileBox
fileName: selectedSp.uiImageNeuDatei
headerText: "Dateiauswahl"
onButtonClicked: selectedSp.onSearchButtonClicked()
}

FileDialog {
id: fileDialog
title: "Auswahl Bild"
onAccepted: selectedSp.onSetFile(fileDialog.selectedFile)
visible: selectedSp.uiViewFileDlg.uiValue
nameFilters: ["JPG Dateien (*.jpg)"]
fileMode: FileDialog.OpenFile
}
< /code>
На Linux и Windows он работает без каких -либо проблем. Но на Android я получаю странное имя файла, которое не может быть открыто:
< /p>
Как можно выбрать файл JPG в каталоге загрузки, например, и открыть его в моей программе C ++? < /P>
