Crash when not overriding `clearItem()` inside `FragmentAdapter`

[Gnzlt]

I found a crash which occurs when using a custom adapter that extends from FragmentAdapter.

Whenever the ViewSwapper makes a call to clearItem() it throws a custom UnsupportedOperationException inside ViewSwapperAdapter since clearItem() is not overrided by default.

E/AndroidRuntime: FATAL EXCEPTION: main

I temporary fixed it by overriding clearItem() with a call to destroyItem() inside my custom FragmentAdapter.

@Override
public void clearItem(ViewGroup container, int position, Object object) {
    super.destroyItem(container, position, object);
}
