Using Iframes in Android Apps
To load an iframe in an Android App, you can use the "loadData" param with the html mime type like this:
WebView myWebView = (WebView) findViewById(R.id.displaymap);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient());
String html = "<iframe style=\"width:100%;height:100%;border:none;border-radius:.5rem;\" " +
"src=\"https://example.com\" ></iframe>";
myWebView.loadData(html, "text/html", null);
