Reading online.. it seems a bug in qt 5.15 with mapbox server..

Solved the issue by upgrading Qt from 5.5 to 5.9.

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.

Hi I've tried:
file:///home/dev/Downloads/OsmOffline/offline_tiles/

This does not work. Am I doing something wrong?

Did it work for you?

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 <...> } <...> }

Hey.... how did you solved this probleam??.
I''m also facing the same issue - white screen.

Thanks.

@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...
