FileDialog does not allow to save a file

In order to save a file I have set the selectExisting: false and selectMultiple: false as documented but in Android there is no input field where to place the filename. Works in Windows 7 and Linux.

    FileDialog {
        id: fileDialog
        selectExisting: false
        selectMultiple: false
        onAccepted: console.log(fileUrl)
    }
