How I can get "error" or "success" from json in kotlin?

Question

I try to make web android app in kotlin and everyday know something but about this error I didn't find solution. I work with OkHTTP3 and for Json I found Klaxon. How I can get from response "success" or "error" only. For example: if I get:

{
"error":{
"code":4,
"text":"\u041d\u0435\u0432\u0435\u0440\u043d\u044b\u0439 \u043b\u043e\u0433\u0438\u043d \u0438\u043b\u0438 \u043f\u0430\u0440\u043e\u043b\u044c!"
}
}

I need to check is it "error" or "success". I tried ```if (response.header("error") toast ("I got error") or

if (response.header("success") {
val i = Intent(this, SecondActivity::class.java).putExtra("token", response.header("session_token").toString)
startActivity(i)

Do I need if ()? Maybe I can check success other way? Thank for all issues and maybe you recommend other library for json?

Why don't you use OkHttp onresponse and onerror methods? you may need to modify the api. please check here https://stackoverflow.com/questions/24246783/okhttp-response-callbacks-on-the-main-thread — Emre Akcan, Dec 10 '19 at 06:14
@EmreAkcanI I can code `val i = Intent(this, SomeActivity::class.java).putExtra("token", response.header("session_token").toString startACtivity(i)` in onResponse? And it will work how if i got success? — savera sleemy, Dec 10 '19 at 07:01

I think that I found solution. I think it's good and work as must.

client.newCall(request).enqueue(object : Callback{

            override fun onResponse(call: Call, response: Response) {

                startActivity(Intent(this@Login, NavigationMenu::class.java)
                    .putExtra("session_token", response
                        .header("session_token")
                        .toString()))
                toast(response.header("text").toString())
            }
