HTTP Client Problem in Xamarin Forms

HTTP Client Problem in Xamarin Forms :
-Problem: Many times HttpClient in PCL Project not working it's give exception if your URL is like:"https" or Your URL is not secure.
- Solution:
1. You can manage your native HttpMessageHandler
Android:

Right click on Android Project -->Properties-->Android Option

Click On Advanced -->

Select "Android" from  HttpClient Implementation DropDown 
Select "SSL/TLS" from SSL/TLS implementation dropdown 


iOS:

Right Click on ios Project->Properties

Select Native HttpClient Handler from HttpClient implementation dropdown

2. You can use dependency Service to use native HttpMessageHandler 

- Create Interface in PCL Project :
 public interface IHttpHandler{
        object GetHttpHandler();
    }
- Create class in android and iOS project for Interface implementation:
Android:
 public class HttpHandlerImp : IHttpHandler
    {
        public object GetHttpHandler()
        {
            var handler = new AndroidClientHandler();
            return handler;
        }
    }

iOS:
 public class HttpHandlerImp : IHttpHandler
    {
        public object GetHttpHandler()
        {
            var nsUrlSession = new NSUrlSessionHandler();
            return nsUrlSession;
        }
    }

HttpClient Handler with Dependency Service:

var handler=(System.Net.Http.HttpMessageHandler)DependencyService.Get<IHttpHandler>().GetHttpHandler();
HttpClient client = new HttpClient(handler);
