try this JsonObject object=new JsonObject(jsonString); your string will be converted to JsonObject.

{"user_id":   "user_id: 140" };

Please make sure that your json string is true.

Example JSON String:

[{"property":"value"}, {"property":"value"}, ...]

OR

{"property":[{"property":"value"}]}

OR

...

So may be your JSON String is not correct.

You can try with (Without ";" at the end of line)

{"user_id":"140"}

If you assign user_id: 140 as value then:

{"user_id":"user_id:140"}

Please make sure that at the end of line have no ;

And, how to parse JSON String???

The first {} => Object, [] => Array

Object without name

JSONObject jObject = new JSONObject(jsonString);
Object without name but in JSONArray

JSONObject jObject = jsonArray.getJSONObject(index); // example: index = 0
Object with name and in JSONArray

JSONObject jObject = jsonArray.getJSONObject("name_of_object");
JSONArray is like JSONObject & jsonArray above is an instance of JSONArray
