How to get user location, using GPS

Question

I need to get user location, when application launched for set marker on Google Map. I found this variant for find user location:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            //Get location and unsubscribe
            locationManager.removeUpdates(this);
            ...
        }
   ...
}

Such method doesn't always work. Usually, application wait for 30 sec - 2 min. But sometimes this doesn't work and I can't take listener response.

How to get user location and take 100% response (if this possibly, when device normal work)?

Answer 1

You can use LocationManager.NETWORK_PROVIDER. It is less accurate comparing to GPS but it is more available.

Answer 2

While you wait for the initial "real" location update to complete, you can get the last location known to the device using

LocationServices.FusedLocationApi.getLastLocation(googleApiClient);

This doesn't guarantee that you will have the most up-to-date location, but it can hopefully give you something relevant to display in the meantime.
