Internet Connectivity Listener in Xamarin.Forms

Question

I am new in Xamarin.Forms and I want to check internet connectivity status in iOS and Android app. In fact using CrossConnectivity Plugins I am able to check internet connectivity successfully but It is not working as Listener. For example, When I open my app and internet connection is not there then it shows me message that "No internet connection" and now if I ON my mobile data then also it shows me same message. I am using below code for this:

string isConnected=CrossConnectivity.Current.IsConnected?"Connected":"No Connection";

My app is not able to listen the changing status of internet connectivity in middle something.

Using the plugin CrossConnectivity, you need to listen to changes via the event ConnectivityChanged, so in your page, or your App class, add this code to write an event handler:

CrossConnectivity.Current.ConnectivityChanged += (sender, args) =>
 {
   //your implementation
  this.DisplayAlert("Connectivity Changed", "IsConnected: " + args.IsConnected.ToString(), "OK");
 };
