 * and updating services.

 * {@link #getLocation} gets the current location using the Location Services getLastLocation()
 * function. {@link #getAddress} calls geocoding to get a street address for the current location.
 * {@link #startUpdates} sends a request to Location Services to send periodic location updates to
 * the Activity.
