Question

send json array object as a parameter to php service from android I've a json object with many string data and a jsonarray data

**ArrayList<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
    HttpResponse httpResponse = null;

    // Making HTTP request
    try {
        // defaultHttpClient
        DefaultHttpClient httpClient = new DefaultHttpClient();
        JSONArray product_array = null;
        /*
         * namevaluepair.add(new BasicNameValuePair("val1",val1));
         * namevaluepair.add(new BasicNameValuePair("val2",val2));
         */

        try {
            nameValuePair = new ArrayList<NameValuePair>();
            nameValuePair.add(new BasicNameValuePair("n", jsonParams
                    .getString("n")));
            nameValuePair.add(new BasicNameValuePair("e", jsonParams
                    .getString("e")));
            nameValuePair.add(new BasicNameValuePair("p", jsonParams
                    .getString("p")));
            nameValuePair.add(new BasicNameValuePair("a", jsonParams
                    .getString("a")));
            nameValuePair.add(new BasicNameValuePair("t", jsonParams
                    .getString("t")));
            nameValuePair.add(new BasicNameValuePair("m", jsonParams
                    .getString("m")));
            product_array = jsonParams.getJSONArray("pj");
            Log.i(TAG + "PPPPJJJ", product_array.toString());
        //  nameValuePair.add(new BasicNameValuePair("pj", product_array
                //  .toString()));
        } catch (Exception e) {
            Log.e(TAG, "2:" + e.getMessage());
        }

        String enc_url = URLEncoder.encode(url);
        HttpPost httpPost = new HttpPost(enc_url);
        httpPost.addHeader("accept", "application/json");
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
        httpResponse = httpClient.execute(httpPost);


    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }**

but it is not forwarding the json array to server,server php file is not receiving that array data, but working fine with browser So I assume problem is in my code.

Error that I am getting while executing the code as below.

You can use my droidQuery library to send this very easily:

$.ajax(new AjaxOptions().url("http://www.example.com")//switch with real URL
                        .type("POST")
                        .dataType("json")
                        .data(jsonParams)//your JSON Object
                        .context(this)
                        .success(new Function() {
                            @Override
                            public void invoke($ droidQuery, Object... params) {
                                //if you are expecting a JSONObject:
                                JSONObject response = (JSONObject) params[0];
                                //TODO: handle response
                            }
                        })
                        .error(new Function() {
                            @Override
                            public void invoke($ droidQuery, Object... params) {
                                AjaxError error = (AjaxError) params[0];
                                $.toast(error.status + ": " + error.reason, Toast.LENGTH_LONG);
                                //retry once
                                $.ajax(error.request, error.options.error($.noop()));
                            }
                        }));

This is how I believe it should be done:

URL url = new URL("//ip of your PHP function on your web server");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
StringBuilder postDataBuilder = new StringBuilder();
postDataBuilder.append(URLEncoder.encode("005", "UTF-8"));
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setUseCaches(false);
urlConnection.setConnectTimeout(10000);
urlConnection.setReadTimeout(10000);
urlConnection.setRequestProperty("Content-Type","application/json");
urlConnection.connect();
JSONObject jsonParam = new JSONObject();
jsonParam.put("item 1", "value 1");
//Add other pairs here, as you are doing
OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream());
out.write(jsonParam.toString());
out.close();
InputStream is = urlConnection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while((line = br.readLine()) != null){
    response.append(line);
    response.append('\n');
}
if (urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
System.out.println(response.toString());
}
else {                                    
    System.out.println("Incorrect response code");
}
br.close();
urlConnection.disconnect();

This code allows you to send the JSON object, then get the response using the InputStream and BufferedReader. Hope this is helpful!

JSONObject j = new JSONObject(); try {
        j.put("n", jsonParams
                .getString("n"));
        j.put("e", jsonParams
                .getString("e"));
        j.put("p", jsonParams
                .getString("p"));
        j.put("e", jsonParams
                .getString("p"));
          j.put("a", jsonParams
                .getString("a"));
        j.put("t", jsonParams
                .getString("t"));
        j.put("m", jsonParams
                .getString("m"));
        product_array = jsonParams.getJSONArray("pj");
        Log.i(TAG + "PPPPJJJ", product_array.toString());

        j.put("array", product_array);
    } catch (Exception e) {
        Log.e(TAG, "2:" + e.getMessage());
    }

    String enc_url = URLEncoder.encode(url);
    HttpPost httpPost = new HttpPost(enc_url);
    httpPost.addHeader("accept", "application/json");
    httpPost.setEntity(new UrlEncodedFormEntity(j));
    httpResponse = httpClient.execute(httpPost);


} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
