Not too sure whats going on. I'm trying to geocode a location in a 2d
array. It always throws this java.lang.NullPointerException exception.
This is my code.
private class SitesOverlay extends ItemizedOverlay<OverlayItem> {
private List<OverlayItem> items=new ArrayList<OverlayItem>();
private Drawable marker=null;
private Geocoder gc;
private List<Address> foundAdd;
private String[][] locations =
{{"home","nairobi"},{"james","Ngara"},
{"pangani","pangani"}};
public SitesOverlay(Drawable marker) {
super(marker);
this.marker=marker;
try{
for( int i =0; i < locations.length; i++ ) {
foundAdd = gc.getFromLocationName(
locations[i][1]+",kenya", 5);
for( int w =0; w < foundAdd.size(); w++ ) {
Address address = foundAdd.get(i);
lat = address.getLatitude();
lon = address.getLongitude();
latitude = (lat * 1000000);
longitude = ( lon * 1000000 );
items.add(new OverlayItem(new GeoPoint(
latitude.intValue() ,
longitude.intValue()),
locations[i][0],locations[i][1]+"\n"));
}
}
}catch(Exception e) {
Log.i("Address not found ", e.toString());
}
populate();
}
@Override
protected OverlayItem createItem(int i) {
return(items.get(i));
}
//draw marker on the map
@Override
public void draw(Canvas canvas, MapView mapView,
boolean shadow) {
super.draw(canvas, mapView, shadow);
boundCenterBottom(marker);
}
@Override
protected boolean onTap(int i) {
Toast.makeText(this,
items.get(i).getSnippet(),
Toast.LENGTH_SHORT).show();
return(true);
}
@Override
public int size() {
return(items.size());
}
}
