                strNewClientCompleteAddress =

                Log.v("strNewClientCompleteAddress:",strNewClientCompleteAddress);


                Geocoder geocoder= new Geocoder(MainActivity.this);

                try {

                        Address fetchedAddress = addresses.get(0);
                        lat = fetchedAddress.getLatitude();
                        lng = fetchedAddress.getLongitude();
                        Log.v("try-if", "ok great work");                       
                    }
                    else {                      
                        Log.v("try-else", "something wrong");                       
                    }

                    }
                    catch (IOException e) {

                        e.printStackTrace();                                    
                        Log.v("catch", "Could not get address....!");

                strLat = String.valueOf(lat);
                Log.v("lat:", strLat);

                Log.v("lng:", strLng);

               ........................
           }

Updated code:

..............
if((addresses != null) && (addresses.size() > 0)) {                
    Address fetchedAddress = addresses.get(0);
    lat = fetchedAddress.getLatitude();
    lng = fetchedAddress.getLongitude();
    Log.v("try-if", "ok great work");                       
}
..............

Log:

V/strNewClientCompleteAddress:(1119): 1701 Amphitheatre Pkwy Mountain View  CA 94043
V/try-else(1119): something wrong
V/lat:(1119): 0.0
V/lng:(1119): 0.0

If your strNewClientCompleteAddress is not valid then addresses might be NULL. and remember one thing .getFromLocationName() not return Location all time. — M D

your logcat clearly indicating--> Caused by: java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0 First check the address.size()>0 then access it. — Rustam

I posted an answer to a similar question, stackoverflow.com/questions/28532520 where the issue was the url needed to start with http:// and the app needed INTERNET use-permission — faljbour

@Rustam now i am not getting any exception and also unable to get latitude and longitude, i have posted updated code and log please check — Sun

@Sun You should use either addresses.isEmpty() == false or addresses.size() > 0. Both does the same. — Pankaj Kumar

try to check addresses.size() > 0

 if ((addresses != null) && (addresses.size() > 0)) {
   Address address=addresses.get(0);
 }

the addresse array size is zero.it means your address array contains no values and you are trying to get the first position of the array value.

before get the value from array need to check null and size like below

 if(addresses!=null && addresses.size()>0)
 { 
 Address fetchedAddress = addresses.get(0);
 }else
  {
       return yourcondition; 
   }

if you need to access current location add this permission to your menifest and try once <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
