Using Nokia Maps with dbus

[chemist]

We had this discussion on IRC (#maemo) lately, about how to start Nokia Maps with dbus. As I do not know if they changed anything within changes of PR1.2-1.3 I can only tell that this is the PR1.3 way we figured to work.

For CLI with Lon./Lat. you may consider a direct step

dbus-send –dest=com.nokia.Navigation.NokiaMapsProvider –type=method_call /Provider com.nokia.Navigation.MapProvider.ShowPlaceGeo double:<latitude> double:<longitude> uint32:0

To get an address you may use this

dbus-send –dest=com.nokia.Navigation.NokiaMapsProvider –type=method_call /Provider com.nokia.Navigation.MapProvider.LocationToAddresses double:<latitude> double:<longitude> boolean:false

it returns a bunch of strings as dbus reply.

What the abook does with a contacts address to open it in Nokia Maps is a AddressToLocation call with the known strings, the dbus reply is the location in Lon./Lat.. Then it calls the ShowPlaceGeo I mentioned first.

Please point me to the thread this is talked about as I found one once but am not able to find it again.

Any additional code snippets for Python C# C++ and others are more than welcome. If anyone does fancy a full AddressToLocation call please tell as I didn't do that yet and am pleased with any further help on fixing this up in here (or the other thread) to have it, once ready, updated at the wiki.

Untested DBus-GLib (http://dbus.freedesktop.org/doc/dbus...mple-program-1) for the ShowPlaceGeo call:

PHP Code:

/* gcc ShowPlaceGeo.c -o ShowPlaceGeo -Wall $(pkg-config --cflags --libs glib-2.0 dbus-glib-1) */
#include <stdlib.h>
#include <glib.h>
#include <dbus/dbus-glib.h>

int main (void)
{
  DBusGConnection *connection;
  GError *error = NULL;
  DBusGProxy *proxy;

  const gdouble latitude = FILLMEIN;
  const gdouble longitude = FILLMEIN;
  
  g_type_init ();

  connection = dbus_g_bus_get (DBUS_BUS_SESSION, &error);
  if (!connection)
    {
      g_printerr ("Failed to open connection to bus: %s\n",
                  error->message);
      g_error_free (error);
      return EXIT_FAILURE;
    }
  
  proxy = dbus_g_proxy_new_for_name (connection,
                                     "com.nokia.Navigation.NokiaMapsProvider",
                                     "/Provider",
                                     "com.nokia.Navigation.MapProvider");

  /* dbus_g_proxy_call_no_reply */
  if (!dbus_g_proxy_call (proxy, "ShowPlaceGeo", &error, G_TYPE_DOUBLE, latitude, G_TYPE_DOUBLE, longitude, G_TYPE_UINT, 0, G_TYPE_INVALID, G_TYPE_INVALID))
    {
      /* Just to demonstrate remote exceptions versus regular GError */
      if (error->domain == DBUS_GERROR && error->code == DBUS_GERROR_REMOTE_EXCEPTION)
        g_printerr ("Caught remote method exception %s: %s",
                dbus_g_error_get_name (error),
                error->message);
      else
        g_printerr ("Error: %s\n", error->message);
      g_error_free (error);
      return EXIT_FAILURE;
    }

  g_object_unref (proxy);

  return EXIT_SUCCESS;
}

Thanks but I was looking for another one and tried some power searching with no luck yet. The CLI snippet and the codes above are more than enough to get a clue how to use the Location framework of OviMaps for now.
