Question

I have this code in Android:

Map<String, String> idObject1 = new LinkedHashMap<String, String>();
            idObject1.put("Id", "Test1");
            idObject1.put("FirstName", "Test Name");
            idObject1.put("LastName", "Test Surname");
            idObject1.put("PhoneNumber", "12345");
Gson gson = new Gson();
json.put("ParticipantIds", gson.toJson(idObject1));
Log.d("Json", json.toString());
Log.d("ParticipantsJson", gson.toJson(idObject1).toString());

The json object also gets other things added to it via the .put method. It’s only messing up at the “ParticipantIds” key.

json.toString()

Outputs

{"ParticipantIds":"{\"Id\":\"Test1\",\"FirstName\":\"Test Name\",\"LastName\":\"Test Surname\",\"PhoneNumber\":\"12345\"}",

and

gson.toJson(idObject1).toString());

Outputs

{"Id":"Test1","FirstName":"Test Name","LastName":"Test Surname","PhoneNumber":"12345"}

I need to remove the \ occurances in the json object when idObject1 is passed into it. It doesn’t necessarily have to use Gson. I only used Gson in an attempt to get it to work. I’ve also tried:

json.put("ParticipantIds", idObject1);

and tried using JSON-Simple to pass it in. I always get the \ escaped character.
I’ve even tried doing .toString() on idObject1 then doing all manner of .replace and .replaceAll methods on it. It doesn’t work!

Answer 1

when u get JsonString replace that escape sequence as given below this works for removing escape sequences

  json.toString().replaceAll("\\\\","");
