How to resolve ItemTapped event not firing in Forms.Android when when MainActivity type is FormsApplicationActivity ?

ItemTapped event won’t get trigged for SfListView in Forms android when using main activity as FormsApplicationActivity. You can overcome this issue in two ways,

Way 1:

You can resolve the issue by inheriting MainActivity.cs from FormsAppCompatActivity. FormsAppCompatActivity is a replacement for FormsApplicationActivity and FormsApplicationActivity is marked as deprecated.

Way 2:
