How to Use the Tizen Native Place API in 4 Steps

Since Tizen 2.4

What is the Place API?

The Place API allows you to discover and explore point of interest (POI) information.

The Place API is one of the Maps Services provided by the Tizen Native Location Framework.

Tizen Native Maps Service API

To start using the Place API:

  1. Create an empty Tizen native application.
  2. Start the Maps Service.
  3. Prepare a place search filter.
  4. Run a place request.


This document assumes that you already have basic knowledge in Tizen development. For basic information, see

The Maps Service API requires a security key issued by the maps provider.
In case of HERE maps, the security key is a concatenation of app_id and app_code, generated on according to your consumer plan.

“your-security-key” is “app_id/app_code”
Note Make sure your device or emulator has a valid internet connection.

To ensure the Maps Service API execution, set the following privileges:

1 Create an Empty Tizen Native Application

In the IDE, create an empty application using the basic UI application template, and run it on an emulator or a device.

Create Empty Tizen Native Project

The "Hello Tizen" label appears on the screen at application startup.

2 Start the Maps Service

To start the Maps Service:

  1. Include the Maps Service API header file in your application:

    #include <maps_service.h>
    Note This inclusion allows you to use all native Maps Service API functions and features. For more details, see, and go to 2.4 API References -> Native Application -> Mobile Native -> Native API Reference -> Location -> Maps Service.
  2. Add a Maps Service handle to the appdata_s structure:
    typedef struct 
       Evas_Object *win;
       Evas_Object *conform;
       Evas_Object *label;
       maps_service_h maps; // Maps Service handle
    } appdata_s;
  3. Create the Maps Service instance in the app_create() function:
    static bool
    app_create(void *data)
       appdata_s *ad = data;
       // Specify the maps provider name
       if (maps_service_create("HERE", &ad->maps) != MAPS_ERROR_NONE)
          return false;
       // Set the security key issued by the maps provider
       maps_service_set_provider_key(ad->maps, "your-security-key");
       return true;
  4. When no longer needed, destroy the Maps Service instance in the app_terminate() function:
    static void
    app_terminate(void *data)
        // Release all resources
        appdata_s *ad = data;

3 Prepare a Place Search Filter

Prepare a search filter to query for places of the "transport" category in the app_create() function:

maps_place_filter_h filter = NULL;
maps_place_category_h category = NULL;
maps_coordinates_h coords = NULL;

// Create a place search filter
// Create a transport category
maps_place_category_set_id(category, "transport");

// Set the place category to the search filter
maps_place_filter_set_category(filter, category);
// Create the central coordinates of the search area
maps_coordinates_create(41.9, 12.5, &coords);
Note For information about the categories for HERE maps, see

4 Run a Place Request

To run a place request:

  1. Add the place request into the app_create() function:

    // Use the Place API
    int request_id = 0;
    maps_service_search_place(ad->maps, coords, 500, filter, NULL, search_place_cb, ad, &request_id);

    After creating the request, release any temporary data:

  2. Implement the place callback:
    static bool
    search_place_cb(maps_error_e error, int request_id , int index, int total,
    		maps_place_h place, void *user_data)
       char *name = NULL;
       int distance = 0;
       maps_place_get_name(place, &name);
       maps_place_get_distance(place, &distance);
       char place_info[0x80] = {0};
       snprintf(place_info, 0x80, "Place \"%s\" is in %d meters", name, distance);
       appdata_s *ad = user_data;
       elm_object_text_set(ad->label, place_info);
       // Release the place handle
       // If return true, you receive other places,
       // corresponding to the search parameters
       // In this example, 1 place is enough
       return false;
  3. Run the application.

    At first, the familiar "Hello Tizen" line appears. A moment later, however, it changes to "Place "Stazione Termini" is in 152 meters".
    This indicates the transportation place is the Stazione Termini station in Rome.
