How to format JSON in Android

I have multiple records in sqlite table, and now i am trying to upload all data on button click

For that i have written below code:

        Cursor cursor = databaseDataHelper.getAllData();

        JSONArray arr = new JSONArray();
        JSONObject jobj ;
        cursor.moveToFirst();

        if(cursor.moveToFirst()) {
        do {
        jobj = new JSONObject();

        try {

            jobj.put("ImageName", cursor.getString(cursor.getColumnIndex("Name")));
            jobj.put("Title", cursor.getString(cursor.getColumnIndex("Title")));

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

        }   while(cursor.moveToNext());

        try { 
        jobj.put("data", arr);
        } catch (JSONException e) { 
            e.printStackTrace();
        }

        String st = jobj.toString();
        Log.d("database::--", st);

        String url = "http://ift.tt/1GKx6ro";

        List<NameValuePair> params = new ArrayList<NameValuePair>(); 
        params.add(new BasicNameValuePair("Data", st));

        String resultServer = helper.getHttpPost(url,params); 
        Log.d("Entire string::", " " + resultServer); 

        /*** Default Value ***/
        strStatusId = "0"; 
        strMessage = ""; 

        try { 
                jsonObject = new JSONObject(resultServer); 
                strStatusId = jsonObject.getString("StatusID"); 
                strMessage = jsonObject.getString("Message"); 
                } catch (JSONException e) { 
                // TODO Auto-generated catch block 
                e.printStackTrace();
            } 
        }

whenever i do tap on button, log says:

database::--(22393): {"data":[],"Name":"Name1","Title":"Title1"}

Whereas it should be something like this:

{"data":[
{
"Name":"Name1",
"Title":"Title1"
},
{
"Name":"Name2",
"Title":"Title2"
}
]}
