DataBase creation on android via unity

I created a sqlite database from unity to run it on android, so I used Apllicantion.persistantDataPath as the path. On pc it works very well, I can create, add, delete and modify data. But in the device it does not work, and I didnt got any error. public void openDB(string p) { connection = "URI=file:" + Application.persistentDataPath + "/" + p; Debug.Log(connection);

             dbconn = new SqliteConnection(connection);
             dbconn.Open();
             dbcmd = dbconn.CreateCommand();
         }
 
         public void closeDB()
         {
             dbcmd.Dispose();
             dbcmd = null;
             dbconn.Close();
             dbconn = null;
         }
 
         public void saveData(string desc, int age, string wants) {
             
             dbconn = (IDbConnection)new SqliteConnection(connection);
             
             string sqlQuery = "INSERT INTO Dados (Descricao, Idade, Interesses) VALUES ('" + desc +"',"+ age + ",'" + wants + "')";
             dbcmd.CommandText = sqlQuery;
             dbcmd.ExecuteNonQuery();
         }
