Question

我正在使用Android地理定位应用，并且我正在使用 com.akexorcist：googledirectionlibrary：1.0.4 库。我曾经使用此代码绘制路线

public void requestDirection(final LatLng origin, final LatLng destination) {
    Toast.makeText(getBaseContext(), "Requesting direction, just a moment...", Toast.LENGTH_SHORT).show();
    GoogleDirection.withServerKey(SERVER_KEY)
            .from(origin)
            .to(destination)
            .transportMode(TransportMode.DRIVING)
            .execute(new DirectionCallback() {
                @Override
                public void onDirectionSuccess(Direction direction, String rawBody) {
                    if (direction.isOK()) {
                        ArrayList<LatLng> directionPositionList = direction.getRouteList().get(0).getLegList().get(0).getDirectionPoint();

                        if (!colorBlue && !path){
                            mGoogleMap.addPolyline(DirectionConverter.createPolyline(getApplicationContext(), directionPositionList, 5, Color.RED));
                        }
                        else if (colorBlue){
                            mGoogleMap.addPolyline(DirectionConverter.createPolyline(getApplicationContext(), directionPositionList, 5, Color.BLUE));
                            colorBlue = false;
                        }else if (cancelled){
                            mGoogleMap.addPolyline(DirectionConverter.createPolyline(getApplicationContext(), directionPositionList, 5, Color.GREEN));
                            cancelled = false;
                        }
                    }else  Toast.makeText(getBaseContext(), "Route suspicious", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onDirectionFailure(Throwable t) {
                    Toast.makeText(getBaseContext(), "An error occured!", Toast.LENGTH_SHORT).show();
                }
            });
}

但现在我总是收到路由可疑消息。调试后，我注意到 directionPositionList 始终为空，即使原点和目的地都不是。任何想法我怎样才能解决这个问题？提前致谢

问题在于Google ServerKey已过期，因此在更改密钥后我能够绘制路径againe。
