为了可以得到调用应用传来的參数，我们也同一时候改动我们的desktop文件例如以下：

[Desktop Entry]
Name=MyApp
Exec=qmlscene $@ main.qml -- %u
Icon=MyApp.png
Terminal=false
Type=Application
X-Ubuntu-Touch=true

为了可以在程序中显示得到的URL信息，我们对程序做了例如以下的改动：

import QtQuick 2.0

２）创建调用应用

     when the device is rotated. The default is false.
    */
    //automaticOrientation: true

    // Removes the old toolbar and enables new features of the new header.
    useDeprecatedToolbar: false

    width: units.gu(100)
    height: units.gu(75)

    Page {
        title: i18n.tr("LaunchMyApp")

        Column {
            spacing: units.gu(1)
            anchors {
                margins: units.gu(2)
                fill: parent
            }

            Button {
                objectName: "button"
                width: parent.width

                text: i18n.tr("Launch MyApp")

                onClicked: {
                    Qt.openUrlExternally("launchmyapp:///123");
                }
            }

            Button {
                objectName: "button"
                width: parent.width

                text: i18n.tr("Open MyApp")

                onClicked: {
                    Qt.openUrlExternally("appid://com.ubuntu.developer.unknown.myapp/MyApp/current-user-version");
                }
            }
        }
    }
}

 Qt.openUrlExternally("launchmyapp:///123");

Qt.openUrlExternally("appid://com.ubuntu.developer.unknown.myapp/MyApp/current-user-version");

假设“MyApp”在已经执行的情况下。能够看到例如以下的右边的画面：
