Org.json.JSONException:Value of type java.lang.String cannot be converted to Jsonobject

Value of type java.lang.String cannot is converted to Jsonobject

The Jsonobject object throws this exception when parsing the JSON string returned by the server.

The JSON format that was supposed to be returned is wrong, and the comparison is hard to see why. At least the character of the format is no problem.

That could be the problem with coding. By carefully comparing each character, it is true that the character is found on the head of the JSON string: "\ufeff".
