class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val webView = findViewById<WebView>(R.id.webView)

        webView.loadUrl("https://en.wikipedia.org/wiki/The_New_York_Times")
    }

    class MyWebViewClient(): WebViewClient() {
        override fun onPageFinished(view: WebView?, url: String?) {
            super.onPageFinished(view, url)

            view!!.evaluateJavascript("javascript:encodeURI(document.documentElement.outerHTML);") {
