How to solve: Failed to parse XML configuration from network_security_config

Question

I'm trying to get json from an api, using okhttp and when i try to do so the app is crushing and i get a runtime Exception

Failed to parse XML configuration from network_security_config

what should i do to solve it? i have INTERNET permission on my manifest. i'v tried to search for something similar on other questions and could't find an answer.

I've tried to follow this tutorial: https://www.youtube.com/watch?v=53BsyxwSBJk

but it seems that there is some problem with the XML but i don't understand it.

here is my class:

class TestActivity : AppCompatActivity() {

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_test)

    val adapter = ArrayAdapter<User>(this, android.R.layout.simple_list_item_1)

    listViewTest.adapter = adapter
    val url = URL(myapi)

    val request = Request.Builder().url(url).build()
    val client = OkHttpClient()
    client.newCall(request).enqueue(object: Callback {

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

            val body = response.body.toString()

            println(body)


        }


        override fun onFailure(call: Call, e: IOException) {


        }



    } )


  }
}

my error log:

Create a folder named xml in res and create a file named config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">Your url</domain>
    </domain-config>
</network-security-config>

add this in Application tag in manifest file.

 android:networkSecurityConfig="@xml/config"

Create a new file under resources/xml naming it as network_security_config.xml -

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">your.url.com</domain>
    </domain-config>
</network-security-config>

Then add this to the Manifest in the application tag -

    android:networkSecurityConfig="@xml/network_security_config"
