Google Maps API v2 を使用して運転ルートを取得するにはどうすればよいですか?

<code class="java">import akexorcist.googledirection.DirectionCallback;
import akexorcist.googledirection.GoogleDirection;
import akexorcist.googledirection.constant.TransportMode;
import akexorcist.googledirection.model.Direction;

// Initialize GoogleDirection
GoogleDirection googleDirection = new GoogleDirection(apiKey);

// Set the departure and arrival locations
LatLng origin = new LatLng(12.917745600000000000, 77.623788300000000000);
LatLng destination = new LatLng(12.842056800000000000, 7.663096499999940000);

// Request directions
googleDirection.withTransportMode(TransportMode.DRIVING)
        .withOrigin(origin)
        .withDestination(destination)
        .execute(new DirectionCallback() {
            @Override
            public void onDirectionSuccess(Direction direction, String rawBody) {
                // Process and display driving directions
            }

            @Override
            public void onDirectionFailure(Throwable t) {
                // Handle direction retrieval error
            }
        });</code>
