Below code is for getting data from online server using GET method and okHTTP library for android kotlin...

Log.e("Main",response.body!!.string())

in above line !! is the thing using which you can get the json from response body

val client = OkHttpClient()
            val request: Request = Request.Builder()
                .get()
                .url("http://172.16.10.126:8789/test/path/jsonpage")
                .addHeader("", "")
                .addHeader("", "")
                .build()
            client.newCall(request).enqueue(object : Callback {
                override fun onFailure(call: Call, e: IOException) {
                    // Handle this
                    Log.e("Main","Try again latter!!!")
                }

                override fun onResponse(call: Call, response: Response) {
                    // Handle this
                    Log.e("Main",response.body!!.string())
                }
            })

As I observed in my code  If once the value is fetched of body from Response  its become blank   String str   response body   string         response      String str1    response body   string        BLANK   So I believe after fetching once the value from body  it become empty   Suggestion   Store it in String  that can be used many time
