    ActivityCompat.requestPermissions(MapsActivity.this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        /*
        tvLatitud.setText("No se tienen permisos");
        ...
         */

        return;
    }else
    {
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        latitude = location.getLatitude();
        longitude =  location.getLongitude();
    }
