Hi All,

I found that the url which my embedded device use to get the route is older one.
http://router.project-osrm.org/viaroute?instructions=true&loc=8.5686,76.8731&loc=8.5241,76.9366 - server replied: Not Found

so i tried to change the url by giving,

PluginParameter { name: "osm.routing.host" value: "http://router.project-osrm.org/route/v1/driving/" }

but the new url which was generated by device is,

http://router.project-osrm.org/route/v1/driving/?instructions=true&loc=8.5686,76.8731&loc=8.5241,76.9366 - server replied: Not Found

the required url should be something like,

http://router.project-osrm.org/route/v1/driving/76.8731,8.5686;76.9366,8.5241?overview=full&steps=true&geometries=polyline&alternatives=true

because of the incorrect format the JSON respone which I receive is "Not Found"

I was able to recreate the issue in PC by giving

PluginParameter { name: "osm.routing.apiversion" value: "v4" }

so i thought if i update the osm.routing.apiversion to v5, I may succeed but i still i got the same error. Please help.

to check if geoclue is working properly simply test if it delivers a position: https://doc.qt.io/qt-5/qml-qtpositioning-positionsource.html#example-usage

@ziiyaa Hello,
Did you solve your problem? I have a similar issue where my Plugin works on a Debian but not on Ubuntu, where the supportedMapTypes array is empty.

Use a separate QObject-derived class and set it as context property.

Other options:

@raven-worx Ah, I was missing the "file:///". Thank you very much.

If someone interesting you can solve problem like this:

C++ side:

QVariantMap params { {"osm.mapping.highdpi_tiles", YOUR_CUSTOM_VALUE}, {"osm.mapping.offline.directory", YOUR_CUSTOM_VALUE}, {"osm.mapping.cache.directory", YOUR_CUSTOM_VALUE} }; QQuickView *view = new QQuickView; view->setSource(QUrl(QStringLiteral("qrc:/qml/OSMView.qml"))); QObject *item = (QObject *) view->rootObject(); QMetaObject::invokeMethod(item, "initializePlugin", Q_ARG(QVariant, QVariant::fromValue(params)));

QML side:

Item { id: osmMain property variant parameters function initializePlugin(pluginParameters) { var parameters = new Array; for(var prop in pluginParameters) { var parameter = Qt.createQmlObject('import QtLocation 5.6; PluginParameter{ name: "'+ prop + '"; value: "' + pluginParameters[prop] + '"}', map) parameters.push(parameter) } osmMain.parameters = parameters map.plugin = Qt.createQmlObject('import QtLocation 5.6; Plugin{ name: "osm"; parameters: osmMain.parameters }', osmMain) } Map { id: map <...> } <...> }

@seb21 I've now managed to fully integrate the QML maps into QWidget application but I also have a working Google Maps plugin with all map types supported.

I can share some code if you like?

I actually prefer the ESRI map implementation over Google Maps and am presently looking at the ArcGIS Runtime SDK stuff for Qt.

@vladstelmahovsky Hi! Better ask this on the developers mailing list, this forum is more for end users.

@QMotza

read about QtPosition read about reverse geocode read about routequeries

yes, you can do whatever you want with Qt, but...you have to read a lot

I just stumbled accros the same odd behavior with Qt 5.7.1. However, the strange thing is, that it seems to be only a problem on android (on windows it's fine). Does anybody know if that's a (already reported) bug?

@Alexander_Lanin didn't see you already found it before I submit my reply...

Our March meetup session materials are now available.
This time, the workshop aim was to discover the Qt.controls.labs. This time, I didn't create a new project for the workshop but used the Gallery example.

@nmnandakishore You are welcome.
By the way, you might be interested in viewing this post containing the materials used during my last meetup which was focus on QtLocation - you could find helpful tips for managing maps, point of interests and route.

Thanks for the google map plugin, I study this post, the codes of your plugin and got some questions

1 : All of the information of google map are obtained by static api of google map?
2 : How could we support offline routing, offline search by term? By now all of the routing information are get from the server, to implement offline routing, we need to

a : download require map, data from the server
b : write our own algorithms to search the locations by terms and routing? I guess every maps data got their own format, but the locations searching and routing algorithms should be the same?

3 : QGeoTileFetcherGooglemaps is the main class of this plugin, which in charge of create request(by static api) and get the results back by the other classes?

Thanks a lot

Run configure in verbose mode to see why it is being skipped. Also, make sure QtLocation folder is there in your source directory.

By just uncommenting the line:
#INSTALLS += target additional

in mapviewer.pro,

It runs up and shows the map on my android phone, great!
