Bluetooth module not found when running qml bluetooth scanner on android

Question

I installed qt5.2 for android and I'm while I'm trying to run an app on my android device whose code is

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtBluetooth 5.0

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

    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            MenuItem {
                text: qsTr("Exit")
                onTriggered: Qt.quit();
            }
        }
    }

    Button {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
}

the app won't run and I get this application output

but it compiles and runs as a desktop app with no errors

Update: it runs on my device if i comment out the import QtBluetooth 5.0 but I'm trying to make an app to use the bluetooth of my device so I need it

QtBluetooth does not support Android at the moment, so this is expected.

Please refer to the documentation for details.

The new Qt Bluetooth module allows you to retrieve information about local Bluetooth devices, scan and retrieve information about devices in range, push files to devices and connect to them using RFCOMM. Qt Bluetooth module is currently supported only for Linux (on BlueZ 4.x) and BlackBerry.

See my other answer from today in a different thread for more details.

Hope this helps.

this is the page of supported features in Qt 5.2 I should have read them before asking http://qt-project.org/wiki/New-Features-in-Qt-5.2 – Abdullah Al-Hatem Dec 25 '13 at 12:05
@redshark: :-) If you read my other answer further on, you will find that BogDan from KDAB may make it work for 5.3 which is probably released around summer time next year, hopefully. – László Papp Dec 25 '13 at 12:06
