FATAL EXCEPTION: main : okhttp3.RealCall.execute

Question

I'm using the OkHttp in my android app to make web requests to a rapidapi API when i click on button . I've already added INTERNET permissions and android:usesCleartextTraffic="true" in my manifest too. But i have error

    AndroidRuntime: FATAL EXCEPTION: main

    Application terminated.

My code

 private fun StartDwonload() {
    val url = editText.text.toString()


        val client = OkHttpClient()

        val requests = Request.Builder()
            .url("xxxxxxxxxxigurl="+url)
            .get()
            .addHeader("x-rapidapi-host", "xxxxxx")
            .addHeader("x-rapidapi-key", "xxxxxxx")
            .build()

        val responses: Response = client.newCall(requests).execute()

        print(responses.body()?.string())


    }

Yes, After button click, it is calling StartDwonload() if not wrong. and inside this, there is network call operation — Kishan Maurya, Feb 03 '20 at 11:23
i have a lot of error when i use that code in your link . can you please post full code with my code ? — Ali Ghassan, Feb 03 '20 at 11:25
That link for reference purposes for NetworkOnMainThreadException. Search for network operation in android kotlin. or share your code link, I will do the required modification if possible. — Kishan Maurya, Feb 03 '20 at 11:29

Code you shared https://play.kotlinlang.org/ via this link, you have used both OkHttp and DownloadManager.

Please use below code,

private fun StartDwonload() {
    val url = editText.text.toString()

        val client = OkHttpClient()

        val requests = Request.Builder()
            .url("https://instagram-facebook-media-downloader.p.rapidapi.com/api?igurl="+url)
            .get()
            .addHeader("x-rapidapi-host", "xxxxxx")
            .addHeader("x-rapidapi-key", "xxxxxxx")
            .build()

       // val responses: Response = client.newCall(requests).execute()

        client.newCall(requests).enqueue(object : Callback {
            override fun onFailure(call: Call, e: IOException) {}
            override fun onResponse(call: Call, response: Response) = println(response.body?.string())
        })
    }

is working after i deleted this line val responses: Response = client.newCall(requests).execute()
