i am trying to show my json string in android listView but Found an Error
Note: i am Using WCF services For converting my data to json format.

Error parsing data org.json.JSONException: Value [{"Id":1,"Name":"Umair","SSN":"11111111"},{"Id":2,"Name":"khan","SSN":"2222222"}] at JSONDataResult of type java.lang.String cannot be converted to JSONArray

My Json String ...
{"JSONDataResult":"[{\"Id\":1,\"Name\":\"Umair\",\"SSN\":\"11111111\"},{\"Id\":2,\"Name\":\"khan\",\"SSN\":\"2222222\"}]"}

My Android Coding :..
protected void showList(){


try {

// myJSON = myJSON.replace("\"","'");
JSONObject jsonObj = new JSONObject(myJSON);

JArray = jsonObj.getJSONArray(TAG_Obj);


for(int i=0;i<jarray mode="hold"> JSONObject c = JArray.getJSONObject(i);


id = c.getString(TAG_ID);
name = c.getString(TAG_Name);
ssn = c.getString(TAG_SSN);


HashMap<string,string> Hashmappersons = new HashMap<string,string>();

Hashmappersons.put(TAG_ID,id);
Hashmappersons.put(TAG_Name,name);
Hashmappersons.put(TAG_SSN,ssn);

ArraypersonList.add(Hashmappersons);

}


ListAdapter listadapter = new SimpleAdapter(

MainActivity.this, ArraypersonList,
R.layout.list_item,
new String[]{TAG_ID,TAG_Name,TAG_SSN},
new int[]{R.id.tv_id, R.id.tv_Name,R.id.tv_SSN}

);

listv.setAdapter(listadapter);

}
catch (JSONException e) {
e.printStackTrace();

Log.v("" + e, "Error" + e);
Log.e("log_tag", "Error parsing data "+e.toString());
Log.e("log_tag", "Failed data was:\n" +listv);

// tv_Er.setText("Error: " + e);

Toast.makeText(getApplicationContext(),""+e+"",Toast.LENGTH_SHORT).show();
}

}


public void getData(){
class GetDataJSON extends AsyncTask<string,> {

@Override
protected String doInBackground(String... params) {

DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());

// HttpPost httppost = new HttpPost(url);

// Depends on your web service
// httppost.setHeader("Accept", "application/json");
// httppost.setHeader("Content-type", "application/json");

HttpGet httpget = new HttpGet(url);
httpget.setHeader("Accept", "application/json");
httpget.setHeader("Content-type", "application/json");

// DefaultHttpClient httpClient = new DefaultHttpClient();


InputStream inputStream = null;
String result = null;
try {
// HttpResponse response = httpclient.execute(httppost);
HttpResponse response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();
inputStream = entity.getContent();

// HttpResponse response = httpClient.execute(request);
// HttpEntity responseEntity = response.getEntity();
// inputStream = responseEntity.getContent();

// json is UTF-8 by default

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);

// BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, HTTP.UTF_8), 8);

StringBuilder sb = new StringBuilder();

String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
result = sb.toString();
} catch (Exception e) {
// Oops
}
finally {
try{
if(inputStream != null)inputStream.close();
}
catch(Exception squish)
{

}
}
return result;
}

@Override
protected void onPostExecute(String result){
myJSON=result;
showList();
}
}
GetDataJSON g = new GetDataJSON();
g.execute();
}
