Criteria c=new Criteria()
c.setAccuracy(Criteria.ACCURACY_FINE);                                      
String providerName=locMgr.getBestProvider(c,true);

                         Location startLocation = new Location(providerName);
                         startLocation.setLatitude(PrevLatitude);
                         startLocation.setLongitude(PrevLongitude);
                         startLocation.set(startLocation);


                         Location _myLoc = new Location(providerName);
                         _myLoc.setLatitude(Double.valueOf(nf.format(location.getLatitude())));
                         _myLoc.setLongitude(Double.valueOf(nf.format(location.getLongitude())));
                         _myLoc.set(_myLoc);


                         double meters = _myLoc.distanceTo(startLocation);
                         double miles = (meters*0.000621371192237334);
