gps 값을 못가져와서 그런겁니다.
갤럭시 같은경우 실내에서 잘 받아 오지 못하는경우가 있습니다.
nowlocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(nowlocation == null){
nowlocation = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Log.i("NETWORK_PROVIDER", "NETWORK_PROVIDER");
}else{
Log.i("GPS_PROVIDER", "GPS_PROVIDER");
}
