Google maps api + landmark

Mobile
#1

Pessoal gostaria de saber como adicionar landmarks ao mapa, por exemplo postos de gasolina, restaurante etc…

Estou seguindo um exemplo do site da nokia para recuperar o mapa e tal mas não idéia de como salvar ou recuperar os landmarks.

Segue o código:[code]

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Vector;

public class GoogleMaps {

“ABCDEFGHIJKLMNOPQRSTUVWXYZ” +
“abcdefghijklmnopqrstuvwxyz” +
“0123456789-_.~”;
private static final char[] HEX = “0123456789ABCDEF”.toCharArray();

// these 2 properties will be used with map scrolling methods. You can remove them if not needed 
public static final int offset = 268435456; 
public static final double radius = offset / Math.PI; 

private String apiKey = "ABQIAAAAcSWmTTwi2zBD4vWLkdQmnBT5yXp_ZAY8_ufC3CFXhHIE1NvwkxRYFjy-Jlg3V421Tfv5QGLRgxJhyg";

    apiKey = key; 
} 

public double[] geocodeAddress(String address) throws Exception { 
    byte[] res = loadHttpFile(getGeocodeUrl(address)); 
    String[] data = split(new String(res, 0, res.length), ','); 

    if (data[0].compareTo("200") != 0) { 
        int errorCode = Integer.parseInt(data[0]); 
        throw new Exception("Google Maps Exception: " + getGeocodeError(errorCode)); 
    }

O ideal seria você estudar a API Location, especificamente a classe LandmarkStore.
