Overview

This code snippet demonstrates how to export all listed landmarks using the Landmarks Platform Service for Flash Lite, supported from S60 5th Edition onwards.

Preconditions

Note: To export landmarks the test device needs to have at least one landmark registered.

Source

// Import Platform Service Interface
import com.nokia.lib.Service;
// Heading of the application
heading_txt.text = "Exporting landmarks";
 
// Create new Service object which has Landmark information
var landmark = new Service("Service.Landmarks", "IDataSource");
 
// Define Array for IDs of the landmarks
var idList:Array = new Array();
 
/**********************************************************
** Function for pressing the List button.
** Calls GetList() method synchronously.
** Method gets list of the landmarks
**********************************************************/

list_mc.onPress = function() {
 
// Define input parameters
var inParams = {Type:"Landmark"};
 
// Define result value
var outParams = landmark.GetList(inParams);
 
// Check if getting the list success
if (outParams.ErrorCode == 0) {
outList = outParams.ReturnValue;
outputEntry = null;
idList = [];
text_txt.text = "";
var i = 0;
do {
outputEntry = outList.next();
if (null != outputEntry) {
i++;
// Get the lists of IDs and landmark information to Arrays
idList.push(outputEntry.id);
 
text_txt.text += "Landmark "+i+"\r"+outputEntry.LandmarkName+
"\r";
} else {
break;
}
} while (true);
} else {
// if errors trace them to the textfield
var errorId = outParams.ErrorCode;
text_txt.text = "Error while listing: "+errorId;
};
};
 
/**********************************************************
** Function for pressing the Export button.
** Calls Export() method synchronously.
** Method exports listed landmarks to the file
**********************************************************/

export_mc.onPress = function() {
 
// Define input parameters
var inputData = {
IdList:idList, DestinationFile:"c:\\Data\\Others\\landmarks.lmx",
MimeType:"application/vnd.nokia.landmarkcollection+xml"
};
var inParams = {Type:"Landmark", Data:inputData};
 
// Define result value
var outParams = landmark.Export(inParams);
if(idList[0]) {
if (outParams.ErrorCode == 0) {
text_txt.text = "All landmarks exported to file";
} else {
var errorId2 = outParams.ErrorCode;
text_txt.text = "Error while exporting: "+errorId2;
};
} else {
text_txt.text = "No landmarks listed!" +
"Press the List button to list all the landmarks to the input.";
};
};

Postconditions

When the List button is pressed, all landmarks are displayed. You can export listed landmarks by pressing the Export button.

Example application

The following sample application has been tested in the Nokia 5800 XpressMusic (S60 5th Edition, Flash Lite 3.0). File:FlashLite Exporting Landmarks.zip
