why GPS returning the same Latitude and Longitude when at travel in Android Device? -

in app, getting location in time interval using alarm manager. here code,

in locationlistenstart.java (it's broadcastreceiver class):-

intent intentp = new intent(context, locationreceiver.class); pendingintent = pendingintent.getbroadcast(context, 0, intentp, pendingintent.flag_one_shot);  criteria = new criteria();  criteria.setaccuracy(criteria.accuracy_fine); provider = locationmanager.getbestprovider(criteria, true); if(provider != null) {     locationmanager.requestsingleupdate(criteria, pendingintent); } 

in locationreceiver.java:-

public class locationreceiver extends broadcastreceiver {    string locationkey = "";    double mlatitude=0.0;    double mlongitude=0.0;    public void onreceive(context context, intent intent)     {      locationkey = locationmanager.key_location_changed;      if (intent.hasextra(locationkey))       {         mlatitude = location.getlatitude();         mlongitude = location.getlongitude();      }      if(locationlistenstart.locationmanager != null)      {         locationlistenstart.locationmanager.removeupdates(locationlistenstart.pendingintent);      }    } }
