MessageDialog not working on Android Qt6.4.0

track

Good Greetings.

I upgraded from Qt6.3 to Qt 6.4 and MessageDialog stopped working properly. When I click the Ok button after deploying to android device, it does not dismiss the the Message dialog. On desktop it works fine.

The Code is :

"import QtQuick
import QtQuick.Controls

import QtQuick.Dialogs

ApplicationWindow{

width: 600
height: 200
visible: true
id:root
color:"green"

Button {
    id: fileButton
    text: "File"
    onClicked: menu.open()

Menu {
id: menu

Action { text: qsTr("Tool Bar");

onTriggered:{console.log("triggered")
root.color="yellow"

}

}
Action { text: qsTr("Side Bar");   }
Action { text: qsTr("Status Bar");   }
Action { text: qsTr("Tool Bar");  }
Action { text: qsTr("Side Bar");   }
Action { text: qsTr("Status Bar");   }

MenuSeparator {
    contentItem: Rectangle {
        implicitWidth: 200
        implicitHeight: 1
        color: "#21be2b"
    }
}

Menu {
    title: qsTr("Advanced")
    // ...
}

topPadding: 2
bottomPadding: 2

delegate: MenuItem {
    id: menuItem
    implicitWidth: 200
    implicitHeight: 40

    arrow: Canvas {
        x: parent.width - width
        implicitWidth: 40
        implicitHeight: 40
        visible: menuItem.subMenu
        onPaint: {
            var ctx = getContext("2d")
            ctx.fillStyle = menuItem.highlighted ? "#ffffff" : "#21be2b"
            ctx.moveTo(15, 15)
            ctx.lineTo(width - 15, height / 2)
            ctx.lineTo(15, height - 15)
            ctx.closePath()
            ctx.fill()
        }
    }

    indicator: Item {
        implicitWidth: 40
        implicitHeight: 40
        Rectangle {
            width: 26
            height: 26
            anchors.centerIn: parent
            visible: menuItem.checkable
            border.color: "#21be2b"
            radius: 3
            Rectangle {
                width: 14
                height: 14
                anchors.centerIn: parent
                visible: menuItem.checked
                color: "#21be2b"
                radius: 2
            }
        }
    }

    contentItem: Text {
        leftPadding: menuItem.indicator.width
        rightPadding: menuItem.arrow.width
        text: menuItem.text
        font: menuItem.font
        opacity: enabled ? 1.0 : 0.3
        color: menuItem.highlighted ? "#ffffff" : "#21be2b"
        horizontalAlignment: Text.AlignLeft
        verticalAlignment: Text.AlignVCenter
        elide: Text.ElideRight
    }

    background: Rectangle {
        implicitWidth: 200
        implicitHeight: 40
        opacity: enabled ? 1 : 0.3
        color: menuItem.highlighted ? "#21be2b" : "transparent"
    }
}

background: Rectangle {
    implicitWidth: 200
    implicitHeight: 40
    color: "#ffffff"
    border.color: "#21be2b"
    radius: 2
}

}

MessageDialog {

    id:messB
    buttons: MessageDialog.Ok
    text: "The document has been modified."
}


Component.onCompleted: {

    messB.open()
}

}

When I add " import Qt.labs.platform " and remove the Button it works fine on android but
when the button is not removed i get this error "W libuntitled30_arm64-v8a.so: QQmlApplicationEngine failed to load component
W libuntitled30_arm64-v8a.so: qrc:/untitled30/main.qml:116:5: Cannot assign to non-existent property "background"
W libuntitled30_arm64-v8a.so: exit app 0"

When i add 'QT += widgets' in .pro file (with the Button not removed) the error does not appear, but the Messagedialog does not respond to dismiss the dialog.

It seem like Qt.labs.platform does not work with other import statements

I finally did a custom MessageDialog

@track Faced the same situation. Did you write your MessageDialog from scratch?

Yes.I created two qml components one that exits after displaying message and the other does not exit.
