[android-developers] android http GET 400 error

[zeeshan]

Hi Android Experts,

i need to make a GET request to the http://www.x.com/server.xml which
takes 3 mandatory headers

hdr1,hdr2,hdr3

i am trying this code

 try {
            String path = "http://x.com/server.xml";;
          HashMap parameters = new HashMap();

          parameters.put("hdr1",this.hdr1);
          if(mUserLoggedIn){
              parameters.put("hdr2",this.hdr2);
              parameters.put("hdr3",this.hdr3);
          }


          // Setup the connection
          String uri = new String(path);

          URL url = new URL(uri);
          URLConnection conn = url.openConnection();
          HttpURLConnection httpConnection = (HttpURLConnection)conn;

          String boundary = "myboundary";
          conn.setDoOutput(true);
          conn.setDoInput(true);
          conn.setUseCaches(false);
          conn.setRequestProperty("Connection","Keep-Alive");
          conn.setRequestProperty("Content-Type","multipart/form-data;
boundary=" + boundary);
          DataOutputStream wr = new DataOutputStream
(conn.getOutputStream());
          // Send the normal form data
          int responseCode = httpConnection.getResponseCode();
          Iterator i = parameters.entrySet().iterator();
          while (i.hasNext()) {
              Map.Entry param = (Map.Entry)i.next();
              wr.write( ("--" + boundary + "\r\n").getBytes() );
              wr.write( ("Content-Disposition: form-data; name=\""+
(String)param.getKey()+"\"\r\n\r\n").getBytes());
              wr.write( ((String)param.getValue() + "\r\n").getBytes
());
              wr.flush();
          }



          wr.close();


         // DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
      //    DocumentBuilder db = dbf.newDocumentBuilder();
       //   Document dom = db.parse(conn.getInputStream());
     //     Element rootElement = dom.getDocumentElement();


responseCode  is 400 which seems a header missing error


any solution?
