NativeScript Disable Zoom on Webview, and load hyperlinks on default browser

ChromeClient.js

// Lets you use webcam and other mobile hardware inside NativeScript WebView

exports.webViewLoaded = function (args) {
  var webview = args.object;
  var TNSWebViewClient =
    android.webkit.WebViewClient.extend({
      shouldOverrideUrlLoading: function (view, url) {
        if (url != null && url.startsWith("http://")) {
          console.log(url);
          // use openUrl form utils module to open the page in a browser
          return true;
        } else {
          return false;
        }
      }

    });
  var TNSWebChromeClient =
    android.webkit.WebChromeClient.extend({
      onPermissionRequest: function (request) {
        request.grant(request.getResources());
      }
    });
  if (isAndroid) {
    webview.android.getSettings().setDisplayZoomControls(false);
    webview.android.getSettings().setBuiltInZoomControls(false);
    webview.android.getSettings().setAllowFileAccessFromFileURLs(true);
    webview.android.getSettings().setAllowUniversalAccessFromFileURLs(true);
    webview.android.getSettings().setMediaPlaybackRequiresUserGesture(false);
    webview.android.getSettings().setUseWideViewPort(true);
    webview.android.getSettings().setDomStorageEnabled(true);
    webview.android.setWebViewClient(new TNSWebViewClient());
    webview.android.setWebChromeClient(new TNSWebChromeClient());
  }
}

NativeScriptWebViewAndroid.js

exports.webViewLoaded = function(args) {
    var webview = args.object;
    var TNSWebViewClient =
        android.webkit.WebViewClient.extend({
            shouldOverrideUrlLoading: function(view, url) {
                if (url != null && url.startsWith("http://")) {
                    console.log(url);
                    // use openUrl form utils module to open the page in a browser
                    return true;

        webview.android.getSettings().setBuiltInZoomControls(false);
        webview.android.setWebViewClient(new TNSWebViewClient());
    } 
}

Is this only for Android?

What is dependency for this? What core modules I have to include to make this work? Thnaks

angular there

import { isAndroid } from 'platform';
declare var android: any;

@Component()

public class YourComponent ... {
    public webViewLoaded(args) {
        const webview = args.object;
        const TNSWebViewClient =
            android.webkit.WebViewClient.extend({
                shouldOverrideUrlLoading: function(view, url) {
                    if (url != null && url.startsWith("http://")) {
                        console.log(url);
                        // use openUrl form utils module to open the page in a browser
                        return true;
                    } else {
                        return false;
                    }
                }
            });
        if (isAndroid) {
            webview.android.getSettings().setDisplayZoomControls(false);
            webview.android.getSettings().setBuiltInZoomControls(false);
            webview.android.setWebViewClient(new TNSWebViewClient());
        } 
    }
}

On Android 21+ the URL needs to be used as openUrl(url.getUrl().toString());
