Geolocation

• Tells your webapp where the user is (demo).
• Works (kinda) even if user has no GPS.
• Use watchPosition to get called whenever the user moves.

var geo = google.gears.factory.create('beta.geolocation');

function updatePosition(position) {
  alert('Current lat/lon is: ' + position.latitude + ',' + position.longitude);
}

function handleError(positionError) {
  alert('Attempt to get location failed: ' + positionError.message);
}

geo.getCurrentPosition(updatePosition, handleError);
