org.json.simple.JSONObject cannot be converted to JSONObject

Question

I get an error when I try to get a JSON object from server after get all objects and put into JSON array:

JSONObject object = null;
try {
     object = jsonArray.getJSONObject(i);
} catch (JSONException e) {
     e.printStackTrace();
}

This code returns:

W/System.err: **org.json.JSONException**:

When I run that in API 23, everything is ok. Is it an issue from API support? How can I solve that?

UPDATE

Inside my activity:

private org.json.simple.JSONArray array_obj = null;

Inside my code, here is where I parse JSON:

if (reader == null)
    reader = new BufferedReader(new InputStreamReader(response.body().byteStream()));

while ((line = reader.readLine()) != null) {
    JSONParser parser_obj = new JSONParser();
    if (array_obj == null) {
        array_obj = (org.json.simple.JSONArray) parser_obj.parse(line);
        jsonArray = new JSONArray(array_obj);
    }
}

and here is my JSON imports:

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import org.json.simple.parser.JSONParser;

Try this :

import org.json.JSONObject;

JSONObject object = new JSONObject();
 try {
    object = jsonArray.getJSONObject(i);
 } catch (JSONException e) {
    e.printStackTrace();
}

Update

You just have to change :

import org.json.JSONObject;

To :

import org.json.simple.JSONObject;

Do the same with JSONArray and JSONException

No, the same error yet. But I think it is a cast error: note -> type org.json.simple.JSONObject cannot be converted to JSONObject – Guilherme Ramos Oct 17 '16 at 18:10
Use `import org.json.JSONObject;` instead – BOUTERBIAT Oualid Oct 17 '16 at 18:11
I'm using that. I'll update my question with more information – Guilherme Ramos Oct 17 '16 at 18:18
Yes you have to import `org.json.JSONObject` instead of `org.json.simple.JSONObject` – BOUTERBIAT Oualid Oct 17 '16 at 18:19
I'm using org.json.simple.JSONObject, but inside my code I have a parser. See my update, please – Guilherme Ramos Oct 17 '16 at 18:23
I tested your edit. But after that, I can't use functions like jsonObject.getString(String name); for example, and I can't get data from server... – Guilherme Ramos Oct 17 '16 at 18:43

Well, I solved my problem changing some parts of my code:

Instead of:

while ((line = reader.readLine()) != null) {
    JSONParser parser_obj = new JSONParser();
    if (array_obj == null) {
        array_obj = (org.json.simple.JSONArray) parser_obj.parse(line);
        jsonArray = new JSONArray(array_obj);
    }
}

I simple wrote:

while ((line = reader.readLine()) != null) {
    JSONTokener tokener = new JSONTokener(line);
    jsonArray = new JSONArray(tokener);

*Based on this question

org.json.simple.JSONObject cannot be converted to JSONObject
