How can I put a Google Map in a Blackberry application without installing google map application?

Question

Many Blackberry applications now use Google Maps (dynamic). How it is done?

Is any open source code available? In a related answer it says to use Google Static Maps API to generate and send images upon device request. This will require server-side implementation.

How it will implement using this method?

}

Use this type For show location on GoogleMap

GMLocation location = new GMLocation(Double.parseDouble("18.646245142670608"), Double.parseDouble("18.646245142670608"),"Niger");
location.invokeGMaps(location);
