网址不会重定向（Android）

Question

我正在尝试从重定向的页面获取JSON，但是现在代码拒绝遵循重定向，即使我特别要求它遵循代码中的重定向。由于这是Android，我在后台线程上运行此函数。它正在努力重定向，此时它会卡在“解析网址”上（有关此特定网址的详细信息，请查看此处：https://developers.soundcloud.com/docs/api/reference#resolve）。这是方法：

class SoundcloudTrackIDAsyncTasker extends AsyncTask<URL, Void, Integer> {

    @Override
    protected Integer doInBackground(URL... params) {
        try {

            URLConnection newURLConnection = params[0].openConnection();
            HttpURLConnection conn =  (HttpURLConnection) newURLConnection;
            conn.setInstanceFollowRedirects(true); // fails, regardless if true or false
            HttpURLConnection.setFollowRedirects(true); // same
            newURLConnection.connect();

            InputStream newURLConnectedStream = newURLConnection.getInputStream();
            System.out.println("" + newURLConnection);
            URL tracksURL =
                    new URL(newURLConnection + "?client_id=" + CLIENT_ID);
            URLConnection trackURLConnection = tracksURL.openConnection();
            trackURLConnection.connect();
            InputStream trackURLConnectionInputStream = trackURLConnection.getInputStream();
            InputStreamReader readHTTPStream = new InputStreamReader(trackURLConnectionInputStream,
                    Charset.forName("UTF-8"));
            Gson gson = new Gson();
            //read the track ID and return it.
            JSONURL urlAsJson = gson.fromJson(readHTTPStream, JSONURL.class);
            return urlAsJson.getTrack();
        } catch (IOException e) {
            return null;
        }
    }
}
