In theory there is no difference between theory and practice. In practice there is

// Set criteria for selecting a location provider: // accurate to 500 meters horizontally Criteria cr = new Criteria(); cr.setHorizontalAccuracy( 500 ); //500m LocationProvider lp = LocationProvider.getInstance(cr); // Request the location, setting a one-minute timeout Location l = lp.getLocation( 60 ); Coordinates c = l.getQualifiedCoordinates(); if (c != null ) { // Use coordinate information double lat = c.getLatitude(); double lon = c.getLongitude(); } JSR 179 (J2ME)

// Set criteria for selecting a location provider:

// accurate to 500 meters horizontally

Criteria cr = new Criteria(); cr.setHorizontalAccuracy( 500 ); //500m LocationProvider lp = LocationProvider.getInstance(cr); // Request the location, setting a one-minute timeout Location l = lp.getLocation( 60 );

Coordinates c = l.getQualifiedCoordinates();

if (c != null ) { // Use coordinate information

double lat = c.getLatitude();

double lon = c.getLongitude();

}
