Try this

FYI

In general all the JSON nodes will start with a square bracket or with a curly bracket. The difference between [ and { is, the square bracket ([) represents starting of an JSONArray node whereas curly bracket ({) represents JSONObject. So while accessing these nodes we need to call appropriate method to access the data. 

JSONObject jsonRootObject = new JSONObject(result);

try 
{
   String strError = jsonRootObject.getString("error");
   String strCode = jsonRootObject.getString("code");

   Log.i("Error",":"+strError);
   Log.i("Code",":"+strCode);
}
catch (JSONException e) 
{
      // TODO Auto-generated catch block
      e.printStackTrace();
}

have you tried getString:

JSONArray arr = new JSONArray(result);
JSONObject jObj = arr.getJSONObject(0);
String mError = jObj.getString("error");
