从 android 中的 news.bitcoin.com 获取 RSS 提要时未找到文件异常

file not found exception while fetching RSS feed from news.bitcoin.com in android

将 link 添加到 RSS 提要:https://news.bitcoin.com/feed/

到目前为止,这是我的代码:

主要活动:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RSSDataDownload downloadTask = new RSSDataDownload();
        downloadTask.execute();
    }

    public static class RSSDataDownload extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... voids) {
            //DOESN'T WORK, FILE NOT FOUND EXCEPTION:
            String MY_URL="https://news.bitcoin.com/feed" ;

                try {
                URL url = new URL(MY_URL);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();


                InputStream inputStream = connection.getInputStream();

                processXML(inputStream);

            } catch (Exception e) {
                e.printStackTrace();
            }

            return null;
        }

        public void processXML(InputStream inputStream) throws Exception {
            DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();

            DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();


           Document XMLdocument= builder.parse(inputStream);

           Element rootElement=XMLdocument.getDocumentElement(); //root element of the XML Document

            Log.d("XML",rootElement.getTagName());

        }
    }


}

以上代码适用于:http://www.bitnewz.net/rss/Feedhttp://bitcoin.worldnewsoffice.com/rss/category/1/ 和其他几个 RSS 提要,但不适用于 https://news.bitcoin.com/feed/

有什么特殊原因吗?如何绕过它?

我不知道你面临的问题是什么,但是 https://news.bitcoin.com/feed/ 通过使用这个库为我工作。

你可以从 RSS-Parser 库中得到这个想法: https://github.com/prof18/RSS-Parser
