I having one doc file on server, and if user click on download. It downloads the file. This works fine in emulator but not working in phone.

Edit
My code for download file

public void downloadFile(String _url, String fileName) {
        File PATH = Environment
                .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
        try {
            PATH.mkdirs();
            URL url = new URL(_url); // you can write here any link
            File file = new File(PATH, fileName);

            long startTime = System.currentTimeMillis();
            Log.d("Manager", "download begining");
            Log.d("DownloadManager", "download url:" + url);
            Log.d("DownloadManager", "downloaded file name:" + fileName);
            /* Open a connection to that URL. */
            URLConnection ucon = url.openConnection();

            /*
             * Define InputStreams to read from the URLConnection.
             */
            InputStream is = ucon.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);

            /*
             * Read bytes to the Buffer until there is nothing more to read(-1).
             */
            ByteArrayBuffer baf = new ByteArrayBuffer(50);
            int current = 0;
            while ((current = bis.read()) != -1) {
                baf.append((byte) current);
            }

            /* Convert the Bytes read to a String. */
            FileOutputStream fos = new FileOutputStream(file);
            fos.write(baf.toByteArray());
            fos.close();
            Log.d("ImageManager",
                    "download ready in"
                            + ((System.currentTimeMillis() - startTime) / 1000)
                            + " sec");

        } catch (IOException e) {
            Log.d("ImageManager", "Error: " + e);
        }
    }

try the snippets given bellow…

File PATH = Environment
                .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
        try {
            //set the download URL, a url that points to a file on the internet
            //this is the file to be downloaded
            _url = _url.replace(" ", "%20");
            URL url = new URL(_url);

            //create the new connection
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            //set up some things on the connection
            urlConnection.setRequestMethod("GET");
            urlConnection.setDoOutput(true);


            //and connect!
            urlConnection.connect();

            //create a new file, specifying the path, and the filename
            //which we want to save the file as.
            File file = new File(PATH,fileName);

            //this will be used to write the downloaded data into the file we created
            FileOutputStream fileOutput = new FileOutputStream(file);

            //this will be used in reading the data from the internet
            InputStream inputStream = urlConnection.getInputStream();

            //this is the total size of the file
            int totalSize = urlConnection.getContentLength();
            Log.i("Download", totalSize+"");
            //variable to store total downloaded bytes
//          int downloadedSize = 0;

            //create a buffer...
            byte[] buffer = new byte[1024];
            int bufferLength = 0; //used to store a temporary size of the buffer

            //now, read through the input buffer and write the contents to the file
            while ( (bufferLength = inputStream.read(buffer)) > 0 ) {
                    //add the data in the buffer to the file in the file output stream (the file on the sd card
                    fileOutput.write(buffer, 0, bufferLength);
            }
            //close the output stream when done
            fileOutput.close();
            return true;

    //catch some possible errors...
    } catch (MalformedURLException e) {
            e.printStackTrace();
    } catch (IOException e) {
            e.printStackTrace();
    }

make sure you have enters the correct download path(url)
