       HttpPost httpPost = new HttpPost(url_src);
HttpParams httpParameters = new BasicHttpParams();
httpclient.setParams(httpParameters);
StringEntity se = new StringEntity(str,"UTF-8");
    se.setContentType("application/json");
httpPost.setEntity(se); 

     httpPost.setHeader("userId", ""+userId);//userID
     httpPost.setHeader("machineId", machineId);//deviceUserMachineID

WebVew's loadUrl() method support headers to be passed. Is there no way to pass headers with postUrl() method? Because with the above method, it will first make httpconnection and pass data to the server, the the response will be set to WebView through loadData() method. – Vivek Mar 20 '14 at 08:03
this is all about for webview @Vivek :) ohk u found all gr8 – Bhanu Sharma Mar 20 '14 at 08:05

I believe this will help: link Doesn't look like you can actually send headers with postUrl(), only with loadUrl() method.

            HttpParams par = new BasicHttpParams();
            //par.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
            int timeoutConnection = 30000;
            HttpConnectionParams.setConnectionTimeout(par, timeoutConnection);
            int timeoutSocket = 10000;
            HttpConnectionParams.setSoTimeout(par, timeoutSocket);

            DefaultHttpClient httpClient = new DefaultHttpClient(par);
         //   httpClient.setParams(par);

            HttpPost httpPost = new HttpPost(url);

                 httpPost = new HttpPost(url);
                 if(postMessage==null)
                     throw new IllegalArgumentException("please send post data as well");
                byte[] data =postMessage.toString().getBytes("UTF-8");

                String base64 = Base64.encodeToString(data, Base64.DEFAULT);
                System.out.println("Base64: "+base64);

                // httpPost.setEntity(new UrlEncodedFormEntity(params));
                  httpPost.setEntity(new StringEntity(base64));

            httpPost.setHeader("token", app.getToken());


           httpResponse = httpClient.execute(httpPost);
           HttpEntity httpEntity = httpResponse.getEntity();


             is = httpEntity.getContent();
               System.out.println("httpEntity.getContent():"+ is );
             BufferedReader reader = new BufferedReader(new InputStreamReader(
              is, "iso-8859-1"));

             StringBuilder sb = new StringBuilder();
             String line = null;
             while ((line = reader.readLine()) != null) {
                 sb.append(line + "\n");
             }
             is.close();
             data = sb.toString();
              //remember httpconnection should be in background thread 
              // if you use asynchtask then upper code should be in doinbackground method 
              //and in onpostexecution do data load in webview

             webview.loadData(data, "text/html","UTF-8");
