How to get accurate GPS location Using google API(Fused Location) in android? -


i using google api location gps in android. got accurate location if moving. if in same location above 15 mins give more locations.

my code is:

public class locationservicetesting extends service         implements locationlistener, connectioncallbacks, onconnectionfailedlistener {        // location updates intervals in sec     private static int update_interval = 10000; // 10 sec     private static int fatest_interval = 5000; // 5 sec     private static int displacement = 10; // 10 meters      locationrequest mlocationrequest;     googleapiclient mgoogleapiclient;     location mcurrentlocation,mlastlocation,test3lastlocation,test2lastlocation;     string mlastupdatetime;       string devicecode = "", imeinumber = "";      protected void createlocationrequest() {                 mlocationrequest = new locationrequest();         mlocationrequest.setinterval(update_interval);         mlocationrequest.setfastestinterval(fatest_interval);         mlocationrequest.setpriority(locationrequest.priority_high_accuracy);         mlocationrequest.setsmallestdisplacement(displacement);     }      private boolean isgoogleplayservicesavailable(context context) {         int status = googleplayservicesutil.isgoogleplayservicesavailable(this);         if (connectionresult.success == status) {             return true;         } else {             googleplayservicesutil.geterrordialog(status, (activity) context, 0).show();             return false;         }     }      public locationservicetesting() {         // todo auto-generated constructor stub     }        @override     public void oncreate() {         // todo auto-generated method stub         super.oncreate();

please me. in advance.....

i refereed link http://www.androidhive.info/2015/02/android-location-api-using-google-play-services/

please me on come problem....

i getting location if in same location enter image description here

i had same issue before few days ago.i have changed setpriority() priority_balanced_power_accuracy. might resolve problem.

you have used priority_high_accuracy in createlocationrequest() method.

instead of line mlocationrequest.setpriority(locationrequest.priority_high_accuracy);

add line mlocationrequest.setpriority(locationrequest.priority_balanced_power_accuracy);

this issue occurred because of onlocationchanged method called priority_high_accuracy , gives new location different.

my suggestion use priority_balanced_power_accuracy.
