I am trying to use geocoding to get the latitudes/longitudes of a given place by passing a street address. This is my code :
String addr = "Shop No. 2, Payal Cinema, Old Delhi Road, Sec-14, Gurgaon";
Geocoder geocoder= new Geocoder(this, Locale.getDefault());
List<Address> addressList = null;
try {
addressList = geocoder.getFromLocationName(addr, 10);
} catch (IOException e) {}
Address address = addressList.get(0);
if(address.hasLatitude() && address.hasLongitude()){
lat = address.getLatitude();
lon = address.getLongitude();
}
The error is in the call to gecoder.getFromLocationName(addr,10) ( I checked it through System.out.println;things don't get printed to the logcat after that line)
Here is the stack trace from LogCat:

you can see there is a java.lang.NullPointerException. i don't know why its arising. Please Help.
Actually latitude and longitude not found for your address please check "addressList" is null or not if it is not null then continue like below..
if (addressList == null)
{
Log.d(TAG,"Latitude and longitude not found");
}
else {
Address location = addressList.get(0);
latitude = location.getLatitude();
longitude = location.getLongitude();
}
