I think I figured out why.
the fragment returned by findFragmentById is located in android.support.v4.app package, why the fragment which PlaceAutocompleteFragment extends is located in a different package
So, Instead of using PlaceAutocompleteFragment, I should be using SupportPlaceAutocompleteFragment
And that fixed it, So the compiler wasn't wrong afterall!
