I have got all the search results for nearby places in an array list, but I am unable to display them on the map.
When I debug my application, adding breakpoint inside the SitesOverlay() constructor, the places are populated, but not if I run as android application.
My code is given below:
public class Map1 extends MapActivity {
private MapView map = null;
private MyLocationOverlay me = null;
double source_lat;
double source_lng;
double destination_lat = 12.899915;
double destination_lng = 80.243969;
Boolean isLocationFound = false;
List<Place> arlPlaces = new ArrayList<Place>();

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new Thread(new Runnable() {
public void run() {
System.out.println("@#@#@#@# main() @#@#@#@#");
String strRequestUrl = "";
try {
URL url = new URL(strRequestUrl);
URLConnection yc = url.openConnection();
BufferedReader in = new BufferedReader(
new InputStreamReader(yc.getInputStream()));
String inputLine;
Place place = null;
while ((inputLine = in.readLine()) != null) {
if (inputLine.contains("name")) {
place = new Place();
place.setStrName(inputLine.substring(
inputLine.indexOf(">") + 1,
inputLine.lastIndexOf("<")));
}
if (inputLine.contains("vicinity")) {
place.setStrAddress(inputLine.substring(
inputLine.indexOf(">") + 1,
inputLine.lastIndexOf("<")));
}
if (inputLine.contains("lat")) {
place.setDblLatitude(Double.valueOf(inputLine
.substring(inputLine.indexOf(">") + 1,
inputLine.lastIndexOf("<"))));
}
if (inputLine.contains("lng")) {
place.setDblLongitude(Double.valueOf(inputLine
.substring(inputLine.indexOf(">") + 1,
inputLine.lastIndexOf("<"))));
arlPlaces.add(place);
}
}
in.close();

You should populate the map after the thread is finished. Your code doesn't wait untill it's finished after the start() method.
I suggest your either try working with a Hanlder at the end of your thread, or that you work with a AsyncTask. I favor the latter.
It probably works during debug because your thread is finished before you add the markers to the map.
