Your app can access the Internet but how would you enable internet permission for your app using Xamarin. By default, the Internet access to the app is not enabled, some setting must be performed before Internet connection to the outside world is allowed.

Google Android App
You will need to go to the Properties of the Android app (right-click the Android app), and enable the “Internet” permission from the Required Permission section from the Android Manifest.

Apple iOS App
For the Apple iOS app, you will have to open the “Info.plist” file using any of your text editor (I am using Sublime in my video), and add the NSAppTransportSecurity and enable the NSAllowsArbitraryLoadsInWebContent parameter.
