+ <div class="cont">
+ <div class="static-cont">
+ <p>The tutorial demonstrates how you can use Maps API in Tizen Applications.</p>
+ <p>Two Maps Providers are supported:
+ <ul>
+ <li><a href="https://developer.here.com">HERE Maps</a> based on <a href="https://developer.here.com/rest-apis">HERE REST API</a></li>
+ <li><a href="http://developer.mapquest.com">MapQuest</a> based on <a href="http://open.mapquestapi.com">Open MapQuest API</a></li>
+ </ul>
+ <p>A user have to get access key of Maps Providers from developer sites</p>
+ <p>Note that Maps Service must be used under "Term of Use" of Maps Service Providers.</p>
+
+ <h2>Warm-up</h2>
+ <p>Become familiar with Location Maps API basics by learning about:</p>
+ <ul>
+ <li><a class="opensection" href="#initial">Initializing the Maps Service</a>
+ <p>Select Maps Provider, check available capabilities, fulfill the
+ prerequisites, creates the instance of Maps Service and destroys it
+ when no longer needed.</p></li>

+ <p>Using Maps API in maps-aware application requires:</p>
+ <ol>

+ <li><p>Creating the Maps Service, relying on the selected Maps Provider,</p>
+ <li><p>Setting Maps Provider access key and other preferences,</p>
+ <li><p>Using Maps Services requests (Geocode, Place Search, Routing),</p>

+ </ol>
+ <p>This Section explains steps 1, 2, 3 and 5. Step 4 is explained in further Sections.</p>
+ <br>
+ <p>Below demonstrated how to start using the Maps Service and API.</p>
+ <ol>
+ <li><p>To use the features of Location Maps API, include the
+ <span style="font-family: Courier New,Courier,monospace;"> <maps_service.h> </span>
+ header file in your application:</p>
+ <pre class="prettyprint">#include <maps_service.h></pre>
+ </li>
+
+ <li><p>Maps Service instance is relying on a particular Maps Provider. In order to get the list of available
+ Maps Providers use
+ <span style="font-family: Courier New,Courier,monospace;"> maps_service_foreach_provider()</span>:</p>
+ <pre class="prettyprint">
+static bool _maps_service_provider_info_cb(char* maps_provider, void* user_data)

+ /* Chose one of providers from the available_providers vector */
+ } else {
+ /* Handle error */
+ }
+}
+ </li>
+
+ <li><p>Create an instance of Maps Service using the
+ <span style="font-family: Courier New,Courier,monospace;"> maps_service_create()</span> function before you use Maps API.</p>
+ <pre class="prettyprint">
+maps_service_h maps = NULL;
+int error = maps_service_create("Maps Provider", &maps);
+ </pre>
+ </li>
+
+ <li><p>Set the security key, appropriate to selected Maps Provider using
+ <span style="font-family: Courier New,Courier,monospace;"> maps_service_set_provider_key()</span>.</p>
+ <pre class="prettyprint">
+error = maps_service_set_provider_key(maps, "XXXYYYZZZ");

+ <span style="font-family: Courier New,Courier,monospace;"> maps_preference_set_property() </span>
+ with key-value pairs, defined in the appropriate Maps Provider documentation.</p>
+ <p>To get preferences, currently applied in the Maps Provider use following functions:</p>
