Download PDF using httpURLConnection

Question

Can anyone help me on downloading PDF (or any file other than HTML) using httpURLConnection class. Reading the input stream line by line from the site using Strings causes a corrupt file download.
Please help !!! Thanks.

Answer 1

you cannot read it line by line. try reading it byte by byte
     URL url = new URL("http://yourserver.com/yourfile.pdf");
     HttpURLConnection conn = (HttpURLConnection)url.openConnection();
     InputStream in = conn.getInputStream();
     ByteArrayOutputStream bos = new ByteArrayOutputStream();
     int i;
     while((i = in.read())!= -1)
          bos.write(i);
     byte [] b = bos.toByteArray();
     FileOutputStream fos = new FileOutputStream("c:\\temp\\test.pdf");
     fos.write(b);
     fos.close();
     conn.disconnect();
