How to use Google Maps Native API with Qt/QML

Hi All,

I wonder if there is any way to use Native Google Maps API ( iOS/Android ) in Qt/QML?
I do not want to use a webview cause there is a request limit (2500 per day) for that.

Thank you very much.

Hi and welcome to devnet,

ICS has a set for modules here that might be of interest.

Hope it helps

Thank you for your suggestion.
I have checked it, but their module seems to use webview too..

As I have mentioned, there is a usage limit for that method ( Maps JavaScript API v3 )

Hi,

to use "Native" API in QML you have to write your own component (as C++ plugin) and use in QML side.

It's pretty easy to write a component using iOS API (you can easily mix C++ and Objective-C code) and you'll find a lot of examples in the Qt docs and searching on the Internet.
About Android you should check if is possible to use Native API from NDK.

What about to use https://developers.google.com/maps/documentation/webservices/ ?? For static Map the limit is 25000 requests/day

We have tried, but no use ( Cannot display native content and QML content at the same time )

25000 is nice, but it's still not enough for us. Actually we do not want any kind of usage limitation in our app.

Anyway thank you for your suggestions.

Is there anyone who has successfully embed Google Map GMSMapView(iOS)/MapView(Android) into QML?
Maybe I implemented incorrectly but the C++ plugin does not work as expectation since it opens map in full-screen and lay on top all QML components.
