Tested in multiple devices and working within API 29

in Kotlin

 val webSettings: WebSettings = webview.settings
    webSettings.javaScriptEnabled = true
    webSettings.useWideViewPort = true
    webSettings.loadWithOverviewMode = true
    webSettings.domStorageEnabled = true

    webview.webViewClient = AppWebViewClients()
// val TERM_CONDITION_URL = "http://docs.google.com/gview?embedded=true&url="
//          + "YOUR_DOC_URL_HERE"

   bindind?.webview?.loadUrl(TERM_CONDITION_URL) 

and here AppWebViewClients class

    class AppWebViewClients : WebViewClient() {
    override fun shouldOverrideUrlLoading(view: WebView, url: String?): Boolean {
        view.loadUrl(url)
        return true
    }

    override fun onPageFinished(view: WebView?, url: String?) {
        if (view?.contentHeight == 0)
            view?.reload();
        else {
            super.onPageFinished(view, url)
        }
    }
}
