Description Prasun Singha Roy 2017-11-01 10:55:50 UTC
I have created a forms page in Xamarin and used that page as a fragment using Xamarin Forms Embedding.

var fragment = new FormsPage().CreateFragment(context);
I would like to override the OnBackPressed() control in Android version of the app. What's the best possible way to do it as I can't override it inside the Xamarin Forms Page.

If you instantiate the Page separately like this:

var page = new FormsPage();
var fragment = page.CreateFragment(this);

You can then call page.SendBackButtonPressed() when needed, which should call the overridden OnBackButtonPressed().
