 new DownloadFileFromURL().execute("http://opengov.dev.ifabrika.ru/upload/435/IF_Заявка_Программист PHP_2013-09-03.docx");

DownloadFileFromUrl是

DownloadFileFromUrl is

 class DownloadFileFromURL extends AsyncTask<String, String, String> {
    private ProgressDialog pDialog;
    public static final int progress_bar_type = 0;

    /**
     * Before starting background thread Show Progress Bar Dialog
     */
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(PostInfoActivity.this);
        pDialog.setMessage("Downloading file. Please wait...");
        pDialog.setIndeterminate(false);
        pDialog.setMax(100);
        pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    /**
     * Downloading file in background thread
     */
    @Override
    protected String doInBackground(String... f_url) {
        int count;
        try {
            URL url = new URL(f_url[0]);
            URLConnection conection = url.openConnection();
            conection.connect();

            // this will be useful so that you can show a tipical 0-100%
            // progress bar
            int lenghtOfFile = conection.getContentLength();

            // download the file
            InputStream input = new BufferedInputStream(url.openStream(),
                    8192);

            // Output stream
            OutputStream output = new FileOutputStream(Environment
                    .getExternalStorageDirectory().toString()
                    + "/test.docx");

            byte data[] = new byte[1024];

            long total = 0;

            while ((count = input.read(data)) != -1) {
                total += count;
                // publishing the progress....
                // After this onProgressUpdate will be called
                publishProgress("" + (int) ((total * 100) / lenghtOfFile));

                // writing data to file
                output.write(data, 0, count);
            }

            // flushing output
            output.flush();

            // closing streams
            output.close();
            input.close();

        } catch (Exception e) {
            Log.e("Error: ", e.getMessage());
        }

        return null;
    }

    /**
     * Updating progress bar
     */
    protected void onProgressUpdate(String... progress) {
        // setting progress percentage
        pDialog.setProgress(Integer.parseInt(progress[0]));
    }

    /**
     * After completing background task Dismiss the progress dialog
     * *
     */
    @Override
    protected void onPostExecute(String file_url) {
        // dismiss the dialog after the file was downloaded
        if (pDialog != null) {
            pDialog.dismiss();
        }
    }

}

在此一看到我的根文件夹中的新test.docx文件，但它的大小为26字节，我不能打开它。

After this a saw new test.docx file in my root folder, but its size is 26 byte and i can not open it.

推荐答案

这发生，因为你的URL在UNI codeD形式，所以你必须先连接code它然后尝试下载

This happening because your url is in unicoded form so you have to first encode it then try to download

        URLEncoder.encode(Url, "UTF-8")

这为我工作。
