Question

在我的跨平台应用程序中，我使用定制的qt geoservices插件，它在桌面应用程序中工作正常。但是，只要我尝试在Android应用中使用它，QML PLugin对象无法加载我的插件，但仍然可以加载qt内置地理服务插件，如此处或 osm 即可。但是，我可以通过QPluginLoader手动加载我的插件：

QPluginLoader loader("libplugins_geoservices_libqtgeoservices_empty.so");
if (loader.load()) {
    qDebug() << loader.metaData();
    loader.unload();
}
loader.setFileName("libplugins_geoservices_libqtgeoservices_osm.so");
if (loader.load()) {
    qDebug() << loader.metaData();
    loader.unload();
}

带输出：

QJsonObject({"IID":"org.qt-project.qt.geoservice.serviceproviderfactory/5.0","MetaData":{"Experimental":false,"Features":["OfflineMappingFeature"],"Keys":["empty"],"Provider":"empty","Version":100},"className":"EmptyGeoServiceProviderFactory","debug":false,"version":328961})
QJsonObject({"IID":"org.qt-project.qt.geoservice.serviceproviderfactory/5.0","MetaData":{"Experimental":false,"Features":["OnlineMappingFeature","OnlineGeocodingFeature","ReverseGeocodingFeature","OnlineRoutingFeature","OnlinePlacesFeature"],"Keys":["osm"],"Provider":"osm","Version":100},"className":"QGeoServiceProviderFactoryOsm","debug":false,"version":328961})

QML代码：

Plugin {
    id: mapPlugin
//        name: "empty" // doesn't work
    name: "osm" // works fine
    Component.onCompleted: console.log(availableServiceProviders) // outputs: "here,osm,mapbox"
}

我在桌面和Android版本中使用Qt 5.5。

在Android应用程序中使用自定义Qt插件
