"Type Dialog unavailable" in Qt 5.9

[kimdata]

I use Qt Quick Dialog on my Android app, and the app quits as soon as I run it with the following error:

W libAppTest.so: (null):0 ((null)): QQmlApplicationEngine failed to load component
W libAppTest.so: (null):0 ((null)): qrc:/main.qml:35 Type Dialog unavailable
W libAppTest.so: file:///data/data/org.qtproject.example.AppTest/qt-reserved-files/qml/QtQuick/Dialogs/DefaultDialogWrapper.qml:45 "qml": no such directory

Here is my source code:

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
import QtQuick.Dialogs 1.2

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

    Page {
        Label {
            text: qsTr("Hello")
            anchors.centerIn: parent

            MouseArea {
                anchors.fill: parent
                onClicked: {
                    dialog.open();
                }
            }
        }
    }

    Dialog {
        id: dialog
        title: "Title"
    }
}

How do I get it to work?

@kimdata Perhaps it's related to QTBUG-60918.

@kimdata Can you use the Dialog which is directly in Controls since 2.1? Just delete import ...Dialogs 1.2 and change import ...Controls 2.2. (version 2.2 is used in the current 5.9 documentation.)

@Eeli-K Thanks. I removed import QtQuick.Dialogs 1.2, modified to import QtQuick.Controls 2.2 and it works.
