Disable ScreenShot in Android - Xamarin.Forms

Taking ScreenShot in device is the best way to keep record at time where you don't want to write it down or you may want to have a copy of it. Android device gives us an opportunity to capture the screen content in the form of Image.

If you don't want the user to capture the screen content for the purpose of security or for some other reason, you can achieve it in a very easy way.

               -  Window.SetFlags(WindowManagerFlags.Secure, WindowManagerFlags.Secure);
