UBER的乘车请求按钮的时间和价格估算不会出现

Question

我按照Uber的Ride请求按钮将如何为Android应用程序提供示例。一切都没问题，直到我想显示我想要的目的地的时间估计和价格。

这是我的代码：

//setting the uber config
private void setupUberConfig() {
    uberSessionConfig = new SessionConfiguration.Builder()
            .setClientId(getString(R.string.uber_client_id))
            .setServerToken(getString(R.string.uber_server_token))
            .setClientSecret(getString(R.string.uber_client_secret))
            .setRedirectUri("http://www.upnixt.com")
            .setScopes(Arrays.asList(Scope.RIDE_WIDGETS, Scope.REQUEST))
            .setEnvironment(SessionConfiguration.Environment.SANDBOX)
            .build();
    UberSdk.initialize(uberSessionConfig);
}


new AsyncTask<Void, Void, String>() {

        @Override
        protected String doInBackground(Void... voids) {
            return currentPlace.getUberXProductId(mContext, MainActivity.getCurrentLocationForOthers().getLatitude(), MainActivity.getCurrentLocationForOthers().getLongitude(),
                    getString(R.string.uber_server_token));
        }

        @Override
        protected void onPostExecute(String productId) {
            super.onPostExecute(productId);
            callUber.setVisibility(View.VISIBLE);
            RideParameters rideParams;
            if (productId != null) {
                 rideParams = new RideParameters.Builder()
                        .setProductId(productId)
                        .setPickupLocation(MainActivity.getCurrentLocationForOthers().getLatitude(), MainActivity.getCurrentLocationForOthers().getLongitude(), "", "")
                        .setDropoffLocation(currentPlace.getLat(), currentPlace.getLng(), currentPlace.getName(), currentPlace.getAddress())
                        .build();
            } else {
                rideParams = new RideParameters.Builder()
                        .setPickupLocation(MainActivity.getCurrentLocationForOthers().getLatitude(), MainActivity.getCurrentLocationForOthers().getLongitude(), "", "")
                        .setDropoffLocation(currentPlace.getLat(), currentPlace.getLng(), currentPlace.getName(), currentPlace.getAddress())
                        .build();
            }

            callUber.setRideParameters(rideParams);
            ServerTokenSession session = new ServerTokenSession(uberSessionConfig);
            callUber.setSession(session);
            callUber.setCallback(new RideRequestButtonCallback() {
                @Override
                public void onRideInformationLoaded() {
                    Log.d("SELLE", "Info Loaded");
                }

                @Override
                public void onError(ApiError apiError) {
                    Log.d("SELLE", apiError.getClientErrors().get(0).getTitle());
                }

                @Override
                public void onError(Throwable throwable) {
                    Log.d("SELLE", "Info Loaded");
                }
            });
            callUber.loadRideInformation();

        }
    }.execute();

我从Uber的v1 / products API获得了产品ID。 我错过了什么？
