Android Location Manager Takes A Long Time Finding Longitude and Latitude

Question

The code I have works when it feels like it. It will either work straight away or will take a very long time, or not work at all. The code is as follow:

 locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
 locationLis = new LocationListener() {
      @Override
      public void onLocationChanged(Location location) {
           lat= location.getLatitude();
           log = location.getLongitude();
           locationManager.removeUpdates(locationLis);
      }
      @Override
      public void onStatusChanged(String s, int i, Bundle bundle){
      }
      @Override
      public void onProviderEnabled(String s) {
      }
      @Override
      public void onProviderDisabled(String s) {
           System.out.println("Not Found");
      }
 };

 locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationLis);

The device I am using to test is a Nexus 7 (2012)

Answer 1

Rather than use the GPS_PROVIDER I changed it to NETWORK_PROVIDER .

This used the network to get the location rather than the GPS which is what took so long. The code was:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationLis);

and now reads:

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationLis);

Answer 2

That may be because your GPS is not getting fixed. Check for the GPS icon, It may be blinking. Thats purely because the GPS is not getting Fixed.

So, I strongly recommend you to test the app under Open Sky . This helps in fixing the GPS faster. And while testing under open sky, you can see that the GPS icon will stop blinking and remains steady.
