I am trying to create an application that allows sending any website as data, but when I write the address it does not load in the second activity.

MainActivity

bt_ir.setOnClickListener {

            val sitio = pt_sitio.text.toString()
            val inten = Intent (this, MainActivity2_Webview::class.java)
            inten.putExtra("Clave", sitio)
            startActivity(inten)
        }

Second Activity

        val intent = intent
        val name = intent.getStringExtra("Clave")
        wv_sitio.loadUrl("http//:${name}")

        bt_atras.setOnClickListener {
            finish()
        }
