JSON parsing in android

 AIM:To parse a Json string in android.
Solution:
 Step 1 ) Declare the json string .

                JSONObject jObject;
String jString = "{\"menu\": {\"id\": \"file\", \"value\": \"File\", \"popup\": { \"menuitem\": [ {\"value\": \"New\",   \"onclick\": \"CreateNewDoc()\"}, {\"value\": \"Open\", \"onclick\": \"OpenDoc()\"}, {\"value\": \"Close\", \"onclick\": \"CloseDoc()\"}]}}}";

Step 2)  convert jString to the jObject by 
              jObject = new JSONObject(jString);
Step 3) Lets extract the menu object by creating a new menu object,
                        JSONObject menuObject = jObject.getJSONObject("menu");
 extract the attributes as follows:
String attributeId = menuObject.getString("id");
Log.i("attributeID:",""+attributeId);

                       String attributeValue = menuObject.getString("value");

                       Log.i("attributeValue:",""+attributeValue);

Ste 4) Final code:

private void JsonParsing() {

JSONObject jObject;

String jString = "{\"menu\": {\"id\": \"file\", \"value\": \"File\", \"popup\": { \"menuitem\": [ {\"value\": \"New\",   \"onclick\": \"CreateNewDoc()\"}, {\"value\": \"Open\", \"onclick\": \"OpenDoc()\"}, {\"value\": \"Close\", \"onclick\": \"CloseDoc()\"}]}}}";

try {

jObject = new JSONObject(jString);

JSONObject menuObject = jObject.getJSONObject("menu");

String attributeId = menuObject.getString("id");

System.out.println(attributeId);

String attributeValue = menuObject.getString("value");

System.out.println(attributeValue);

JSONObject popupObject = menuObject.getJSONObject("popup");

JSONArray menuitemArray = popupObject.getJSONArray("menuitem");

for (int i = 0; i < 3; i++) {

Log.i("Value",menuitemArray.getJSONObject(i)

.getString("value").toString());

Log.i("Onclick:", menuitemArray.getJSONObject(i).getString(

"onclick").toString());

}

} catch (Exception e) {

e.printStackTrace();

}

}
