Webpage is getting loaded inside Xamarin forms webview, links with target="_blank" not working on android
<a href="" target="_blank"></a>

I have created custom renderer as per this, it solves the issue, however I want all the links with target=_blank opens up external browser instead of within webview.

Please suggest

    You have set Control.Settings.SetSupportMultipleWindows(true);, you need to create a WebChromeClient as well, and open the browser in the OnCreateWindow method like following code.

       Control.SetWebChromeClient(new MyWebChormeClient());  
       internal class MyWebChormeClient : Android.Webkit.WebChromeClient  
               public override bool OnCreateWindow(Android.Webkit.WebView view, bool isDialog, bool isUserGesture, Message resultMsg)  
                   HitTestResult TestResult = view.GetHitTestResult();  
                   string data = TestResult.Extra;  
                   Context context = view.Context;  
                   var uri = Android.Net.Uri.Parse(data);  
                   Intent browserIntent = new Intent(Intent.ActionView, uri);  
                   return false;  

    Note: I test this <a> in local html. I get the result "file:///android_asset/%60" from string data = TestResult.Extra; line, So I need to Substring with Regex by string startString="%60" and string endString="%60", You need to handle it by your usage environment.

       public string Substring(string text, string start, string end)  
                   Regex regex = new Regex("(?<=(" + start + "))[.\\s\\S]*?(?=(" + end + "))", RegexOptions.Multiline | RegexOptions.Singleline);  
                   return regex.Match(text).Value;  

    Best Regards,
