latitude long. pass through Geopoint() ,problem in number format

I have done xml parsing and store result as latitude and longitude in an StringArray and using for loop I store result of lat and longitude in a string named "lat" and "longi" I want to pass these points through GeoPoint() for showing in a map,now the problem is now that i have 43 items in array: "sitesList.getLatitude().size()" when i use in our for loop it force close it is showing only 20 items show when i hard coated it then it is showing all lat long in map so now my qus is how to show all 43 position in mymap???

  **if i use this then force close and gives number format exceptions...**
  ****// for (int i = 0; i < sitesList.getLatitude().size(); i++)****

and when i take max size 20 then no problem occur why???

        for(int i=0;i<20;i++)
{
     name = sitesList.getLatitude().get(i);
     name1 = sitesList.getLongitude().get(i);
     Log.i("array_spinner" + i, name);
     Log.i("longitiitude"+i,name1);
     point = new GeoPoint((int) (Double.parseDouble(name) * 1E6),
                (int) (Double.parseDouble(name1) * 1E6));
                 OverlayItem overlayItem = new Over开发者_如何学GolayItem(point, "Tomorrow ", 
                 "(M gives Bond his mission in Daimler car)");
                 itemizedOverlay.addOverlay(overlayItem);
}

It seems like a data in your sitesList contains null values (excatly at position 20) or it contains values, that can'be parsed as Double.

In first case you are getting NullPointerException, and in the second one - NumberFormatException.

P.S. I have seen this bug before... exactly here: Show marker on google map position obtained from xml
