You can open BlackBerry Maps to display the default map view by invoking Invoke.invokeApplication() and passing in a new MapsArguments object. How the default view is displayed depends on whether the 'On App Launch' setting in BlackBerry Maps is set to 'Show my location' or 'Show previous location'.

1. Import the required classes.

   import net.rim.blackberry.api.invoke.*;

2. Create a class and a constructor to use to invoke BlackBerry Maps.

   public class invokeMaps
   {
       public invokeMaps()
       {
       }
   }

3. In the constructor, invoke Invoke.invokeApplication() to open BlackBerry Maps. Pass in a new MapsArguments object.

   Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments());
