[unsolved]QML is slow in Android

flaviomarcio

QML is slow in Android 4.1 ARMv5 or ARMv7 of 1.2 ghz.

delay in the design of items in listview.
nothing good result.
is not good. In the windows7 was perfect.

I'm doing something wrong?

import QtQuick 1.1

Frame {
id: container
width: 200
height: 250
showBorderImage: true;

ListModel {
    id: animalsModel
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
    ListElement { menuText: "menuX"}
}

ListView {
    id:listView
    anchors.fill: parent
    model: animalsModel
    delegate:
        Text
        {
            width: listView.width
            text: menuText
        }
}

}

Are you using Qt 5? (it's a good idea to do so -- all the recent work in Android support has been exclusive to Qt 5)

Qt Quick 1 is deprecated, and is only provided for Qt 4 compatibility. Use Qt Quick 2 instead -- you should see improvements

I have not found what you need to qt5.

Are you able to install?

While you can wait for Qt 5.1 release later this month.

Hi

I experienced the same: my app started in 22 segs using QT 5.2.

The solution was to put all qml files in a resource file. Just see the android extras notification example:

https://qt.gitorious.org/qt/qtandroidextras/source/09c0570ce76576074fa0dd98276d959fe0287317:examples/androidextras

Hope this helps

I'm also always putting my qml files into a resource file so just give it a try, maybe it'll fix it.
