Question

My app find out current location using GPS. It is working fine in outdoor. But where GPS is not available or poor it is trying to get update again and again and it drains battery. So i want to stop update when GPS is poor or unavailable. You may suggest to use

lm.removeUpdates(locationlistenerforGPS);

It is working fine when GPS is available not in indoor. I like to stop update when GPS is poor or unavailable.

my code is

LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationListener locationlistenerforGPS = new mylocationlistenerGPS();
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationlistenerforGPS);

My locationlistenerGPS() function is

 private class mylocationlistenerGPS implements LocationListener {
  @Override
  public void onLocationChanged(Location location) {
      counterGPS++;
      if (location != null) {
      Log.d("LOCATION CHANGED", location.getLatitude() + " ");
      Log.d("LOCATION CHANGED", location.getLongitude() + " ");
      Toast.makeText(LocationActivity.this,"latitude: "+
          location.getLatitude() + "longitude: " + location.getLongitude()
          + " Provider:" + location.getProvider() + " Accuracy:" + location.getAccuracy(),
          Toast.LENGTH_LONG).show();
      }

  }
  @Override
  public void onProviderDisabled(String provider) {
  }
  @Override
  public void onProviderEnabled(String provider) {
  }
  @Override
  public void onStatusChanged(String provider, int status, Bundle extras) {
  }
  }

Thank you very much for any kind of assistance.

Don’t use minTime and minDistance set to zero in requestLocationUpdates(). See requestLocationUpdates() documentation.

Bundle extras in onStatusChanged() may include satellites – the number of satellites used to derive the fix, this way you can define poor signal or you can use NmeaListener if you need additional information from GPS.
