title: "A JSONArray text must start with '[' at character 1 of null"
body: <p>Just wondering what that error could mean? I get it from the following code..</p>
  
  <pre><code> try{
      JSONArray jArray = new JSONArray(result);
      for(int i=0;i&lt;jArray.length();i++){
              JSONObject json_data = jArray.getJSONObject(i);
              Log.i("log_tag","id: "+json_data.getInt("id")+
                      ", name: "+json_data.getString("name")+
                      ", sex: "+json_data.getInt("sex")+
                      ", birthyear: "+json_data.getInt("birthyear")
              );
      }
  }
  }catch(JSONException e){
      Log.e("log_tag", "Error parsing data "+e.toString());
  }
