Registering Map Api

[catharsis]

If you have an application with maps (take mapsdemo, for example), when you initialize maps widget you have this message:

[Qt Message] ******************************************************************************** 
[Qt Message] Qt Location requires usage of app_id and token parameters obtained from: 
[Qt Message] https://api.forum.nokia.com/ovi-api/ui/registration 
[Qt Message] For more information about app_id and token please consult: 
[Qt Message] http://doc.qt.nokia.com/qtmobility-latest/location-overview.html#the-nokia-plugin 
[Qt Message] ********************************************************************************

I went to https://api.developer.nokia.com/ovi-...on?action=list and got an App Id, but I still get the message when I run my application and in some cases my app crashes because of the map.

I init the service provider like this:

QMap<QString, QVariant> params;
    params.insert("mapping.app_id", MY_APP_ID);
    params.insert("routing.app_id", MY_APP_ID);
    params.insert("places.app_id", MY_APP_ID);
    params.insert("mapping.token", MY_APP_TOKEN);
    params.insert("routing.token", MY_APP_TOKEN);
    params.insert("places.token", MY_APP_TOKEN);

    foreach (QString provider, providers) {
        serviceProvider = new QGeoServiceProvider(provider, params);
        if (serviceProvider->mappingManager() &&
                serviceProvider->searchManager() &&
                serviceProvider->routingManager())
            break;
    }

I'm running this on a phone with QtMobility 1.2.1 and I still get the same message. Is there something I missed or something I'm doing wrong?

PS: My app token is something like SOME_LETTERS_AND_NUMBERS_7kA%3D%3D. Could there be some errors in its generations, since %3D is url encoding for "=" ?
Also there is a "Secret" string provided in registration, where do I use it?

Hello,

There was a bug in the logic to display this message, I reported it on the Bug Tracker (https://bugreports.qt.nokia.com/browse/QTMOBILITY-1922) some weeks ago and I think it has been fixed recently (last week), maybe you can find the new code in the master branch of the Gitorious repository (https://qt.gitorious.org/qt-mobility).

Concerning the crashes, I also experience a lot of crashes when using QGeoMapCustomObjects, I had to fix 3-4 things in the code but it still crashes when I draw circles on custom objects with MeterUnits for very obscure reasons (some assert in QPainterPath)...

Best regards,
Alexandre H.

Hi Habersaa

Are you sure that this bug is been fixed already? Because I meet the same problem when I apply the almost same code. both the app_id and token are got when I registered my program for Map API used

QMap<QString, QVariant> params;
params.insert("mapping.app_id", "FLVrBWgh_7Zi_NifYost");
params.insert("routing.app_id", "FLVrBWgh_7Zi_NifYost");
params.insert("places.app_id", "FLVrBWgh_7Zi_NifYost");
params.insert("mapping.token", "eP9raM74ACwAvGjnKzbGwA%3D%3D");
params.insert("routing.token", "eP9raM74ACwAvGjnKzbGwA%3D%3D");
params.insert("places.token", "eP9raM74ACwAvGjnKzbGwA%3D%3D");

QList<QString> providers = QGeoServiceProvider::availableServiceProviders();
QGeoServiceProvider *serviceProvider;

foreach (QString provider, providers){
serviceProvider = new QGeoServiceProvider(provider,params);
if (serviceProvider->mappingManager() &&
serviceProvider->searchManager() &&
serviceProvider->routingManager())
{

break;
//w.initialize(serviceProvider->mappingManager());
}

}

In my application it used to crash because I initialized map widget in constructor of the MainWindow. The error made the constructor crash and be recalled until it crashed the application.

Funny thing is that if I use token and app id, map routing does not work, I get "Forbidden" error from routing server. So I commented all the code regarding parameters and I get the Location API error once and then it works.

What I have posted before was wrong, so I had to edit it
