  char[] utf8 = null;
            StringBuilder properString = new StringBuilder("");

            utf8 = Response.toCharArray();

            for (int i = 0; i < utf8.length; i++) {
                if ((int) utf8[i] < 65000) {
                    properString.append(utf8[i]);
                }
            }
  System.out.println("Response of Login::"

To remove character like (\n) or unwanted character in json string used commons-lang3:3.4 library in program . i used this class to remove unwanted character in json string "StringEscapeUtils.unescapeJava(string)".

this will help you.

Had similar problem. At first my app was working great on both androids 4.0+ and 4.0- (2.3.3 2.2 etc). after a revision i have that problem. JSonarray could parse on 2.3.3

PROBLEM: Json STRING (response from server) comes with a character ' in front so actual response= '[{"1":"omg"}] and not the correct one [{"1":"omg"}]

Solution: if string dosent start with [ then edit response string (remove the ' character)

  if (result.startsWith("["))
      {



      }
      else
      {
          result= result.substring(1);
      }

after then everything worked fine for me

If you are a using json-lib-2.4 as library, which I assume, you can parse strings with :

JSONSerializer.toJSON(yourString).toString() 

instead of using the JsonObject class
