Parsing multiple Json Objects in android

Question

I am trying to send this json to web server:

[{"codemenu":"1","name":"Fried Rice"},
{"codemenu":"2","name":"Hongkong Fried Rice"},
{"codemenu":"3","name":"Special fried Rice"}]

This is the code but it's not working:

HttpPost httppost = new HttpPost("http://10.0.2.2/pnir_restoran/test.php");
JSONObject json = new JSONObject();
try {
    // JSON data:
    json.put("codemenu", "1");
    json.put("name", "friedrice");
    json.put("codemenu", "2");
    json.put("name", "Hongkong friedrice");
    json.put("codemenu", "3");
    json.put("name", "Special friedrice");          

    JSONArray postjson=new JSONArray();
    postjson.put(json); //i cant use postjson.add(json);

    // Post the data:
    httppost.setHeader("json",json.toString());
    httppost.getParams().setParameter("jsonpost",postjson);

    // Execute HTTP Post Request
    System.out.print(json);
    HttpResponse response = httpclient.execute(httppost);

What should I do? Please help me.

Have you displayed the JSON that's being generated? What you're generating is not what you say you want. — Hot Licks

(You're creating one JSON object and putting 6 entries in it. The JSON prototype you list contains 3 objects, each with 2 entries.) — Hot Licks

(It also doesn't make sense that you're putting the JSON object in the header and the array in the params.) — Hot Licks

You need to use a JSONArray and then put individual JSONObjects inside the array:

// Initialize the JSON Array and your three seperate objects.
JSONArray jsonArray = new JSONArray();
JSONObject jObj1 = new JSONObject();
JSONObject jObj2 = new JSONObject();
JSONObject jObj3 = new JSONObject();

// Put elements in one object at a time and put them in your array.
jObj1.put("codemenu", "1");
jObj1.put("name", "friedrice");

jsonArray.put(jObj1);

jObj2.put("codemenu", "2");
jObj2.put("name", "Hongkong friedrice");

jsonArray.put(jObj2);

jObj3.put("codemenu", "3");
jObj3.put("name", "Special friedrice");

jsonArray.put(jObj3);

Instead of doing all JSON handling manually, you can use Spring Android's RestTemplate module.
