json - (Android) JSONObject cannot be converted to JSONArray -

my below android code throwing

org.json.jsonexception: value {"id":1,"displayname":"manish","username":"manish.parab@hotmail.com"} @ authenticateuserresult of type org.json.jsonobject cannot converted jsonarray

code:

 string response = common.executehttprequest(url);  jsonobject jsonobject = new jsonobject(response);  jsonarray jarray =  jsonobject.getjsonarray("authenticateuserresult"); 

response string wcf method.

{"authenticateuserresult":{"displayname":"manish","id":1,"username":"manish.parab@hotmail.com"}}

the exception right, because "authenticateuserresult" value declared element ({}) , not array ({}).

to fix this, use getjsonobject method value of "authenticateuserresult", this:

string response = common.executehttprequest(url); jsonobject jsonobject = new jsonobject(response); jsonobject result =  jsonobject.getjsonobject("authenticateuserresult"); 

after that, can retrieve child element, like:

string musername = result.getstring("username");
