Android's simple method to obtain latitude and longitude

     (Criteria.ACCURACY_FINE);// High precision     (false);// No alignment required     (false);// No position required     (true);// Allows for expenses     (Criteria.POWER_LOW);// Low power consumption     // From available location providers, match the best providers of the above standards     provider = (criteria, true);
     // Get the last change position     location = (provider);
     locationListener = new LocationListener() {

     }
