Youtube网址格式错误的网址例外

Question

我正在使用以下功能获取一个网址，以便从我的Android设备上传视频到Youtube：

班级变量：

private static final String INITIAL_UPLOAD_URL = "http://uploads.gdata.youtube.com/resumable/feeds/api/users/default/uploads";

功能：

private static String uploadMetaData(YoutubeUploadRequest uploadRequest, String clientLoginToken, Activity activity, boolean retry) {
        System.out.println("Upload Request \n"+uploadRequest+"\n Client login token"+clientLoginToken+"\nActivity: "+"\nActivity name: "+activity+"\nRetry value:"+retry); 
        try {

            File file = getFileFromUri(uploadRequest.getUri(), activity);

            if(file != null) {

                String uploadUrl = INITIAL_UPLOAD_URL;
                System.out.println(uploadUrl); 
                URL url = new URL(uploadUrl);

                System.out.println(url);

                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setRequestProperty("Authorization", String.format("GoogleLogin auth=\"%s\"", clientLoginToken));
                connection.setRequestProperty("GData-Version", "2");
                connection.setRequestProperty("X-GData-Client", CLIENT_ID);
                connection.setRequestProperty("X-GData-Key", String.format("key=%s", DEVELOPER_KEY));

                connection.setRequestMethod("POST");
                connection.setDoOutput(true);
                connection.setRequestProperty("Content-Type", "application/atom+xml");
                connection.setRequestProperty("Slug", file.getAbsolutePath());

                String title = uploadRequest.getTitle();
                String description = uploadRequest.getDescription();
                String category = uploadRequest.getCategory();
                String tags = uploadRequest.getTags();

                String template = readFile(activity, R.raw.gdata).toString();
                String atomData = String.format(template, title, description, category, tags);

                /*String template = readFile(activity, R.raw.gdata_geo).toString();
                atomData = String.format(template, title, description, category, tags,
                    videoLocation.getLatitude(), videoLocation.getLongitude());*/

                OutputStreamWriter outStreamWriter = new OutputStreamWriter(connection.getOutputStream());
                outStreamWriter.write(atomData);
                outStreamWriter.close();

                int responseCode = connection.getResponseCode();

                if (responseCode < 200 || responseCode >= 300) {

                    // The response code is 40X

                    if ((responseCode + "").startsWith("4") && retry) {

                        Log.d(TAG, "retrying to fetch auth token for ");

                        clientLoginToken = getClientAuthToken();

                        // Try again with fresh token
                        return uploadMetaData(uploadRequest, clientLoginToken, activity, false);
                    } else {
                        return null;
                    }
                }
                System.out.println(connection.getHeaderField("Location"));
                return connection.getHeaderField("Location");

            }

        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("Message"+e); 
        }

        return null;
    }

我确定我传递给函数的参数，它们都是正确的。我通过调试交叉检查，我将此函数称为：

String uploadUrl = uploadMetaData(uploadRequest, authToken, activity, true);

但是我收到错误，格式错误的网址异常，我知道哪里可能出错？

这些是我传递的参数：
