QML and google maps api key



  • Hi all,

    I'm having problems trying to set google maps api key for my project. Everything works well on debug mode but on release mode the map is not shown. I suppose this is because of the Api Key.
    I have created my project on google console and enabled the google maps api key so I think the problem is on the code side.
    This is my code:

    import QtQuick 2.7
    import QtQuick.Controls 1.4
    import QtQuick.Window 2.0
    import QtLocation 5.6
    import QtPositioning 5.6
    
    Rectangle {
        id: mainWindow
        width: 512
        height: 512
        visible: true
    
        ListModel{
            id:dummyModel
            ListElement {
                Latitude: 47.212047
                Longitude: -1.551647
                Label: "something"
                Orientation: 0
                Color:"transparent"
            }
       }
    
        Plugin {
            id: googleMaps
            name: "googlemaps" // "mapboxgl", "esri", ...
            // specify plugin parameters if necessary
             PluginParameter {
                 name:"googlemaps.maps.apikey"
                 value:"*******My Api Key*********"
             }
    
        }
    
        Map {
            id: myMap
            anchors.fill: parent
            plugin: googleMaps
            activeMapType: supportedMapTypes[1]
    
            center: QtPositioning.coordinate(59.91, 10.75) // Oslo
            zoomLevel: 14
    
            MapItemView{
                id:dynamicMapObject
                model: dummyModel
                delegate: MapQuickItem {
                    coordinate: QtPositioning.coordinate(Latitude,Longitude)
                    sourceItem:  Text{
                        width: 100
                        height: 50
                        text: model.Label
                        rotation: model.Orientation
                        opacity: 0.6
                        color: model.Color
                    }
                }
            }
    
            MapPolyline {
                    line.width: 3
                    line.color: 'green'
                    path: [
                        { latitude: 59.92, longitude: 10.77 },
                        { latitude: 59.96, longitude: 10.78 },
                        { latitude: 59.99, longitude: 10.76 },
                        { latitude: 59.95, longitude: 10.74 }
                    ]
            }
    
            MapCircle {
              //a static item (fixed real dimension) always at 100m east of the map center
              id:prova
              center: myMap.center.atDistanceAndAzimuth(100,90)
              opacity:0.8
              color:"red"
              radius:30
    
            }
        }
    
        Button{
            id:buttonMap
            text:"Click to add name"
            onClicked: {
                if(buttonMap.text == "Click to add name")
                {
                    buttonMap.text = "Click to cancel name"
                    myMap.activeMapType = myMap.supportedMapTypes[3]
                }
                else
                {
                    buttonMap.text = "Click to add name"
                    myMap.activeMapType = myMap.supportedMapTypes[1]
                }
            }
        }
    
        GroupBox{
               title:"map types"
               ComboBox{
                   model:myMap.supportedMapTypes
                   textRole:"description"
                   onCurrentIndexChanged: myMap.activeMapType = myMap.supportedMapTypes[currentIndex]
               }
         }
    }
    

    I followed this topic (https://forum.qt.io/topic/66725/open-source-map-plug-in-for-qml/24).
    Am I doing something wrong writing the plugin parameters? Am I missing something?

    Is there a way to see if google api key has been setted well? Or something so that I can understand that the api key is wrong.

    Any suggestion would be helpful.
    Thanks in advance.



  • The problem was not the apikey. Here is the answer to the question https://forum.qt.io/topic/90126/problem-with-qml-and-google-maps-plugin/3
