How do you read and write a JSON file on android

I have a database made and I have trouble with reading and writing to it when I build the game for android it says it can't find the certain parts of the path. Here is the code to read it

       string jsn = File.ReadAllText(Application.dataPath + "/ItemDataBase_TicTacToe/Items.json");
             Debug.Log(jsn);
             itemData = JsonMapper.ToObject(jsn);
             Debug.Log(Application.persistentDataPath);
             Debug.Log(Application.dataPath + "Data pahth");
             ConstructItemDatabase();
