<div class="block">Provides access to all root views in an application.
95% of the time this is unnecessary and we can operate solely on current Activity's root view
as indicated by getWindow().getDecorView(). However in the case of popup windows, menus, and
dialogs the actual view hierarchy we should be operating on is not accessible thru public apis.
In the spirit of degrading gracefully when new api levels break compatibility, callers should
handle a list of size 0 by assuming getWindow().getDecorView() on the currently resumed activity
is the sole root - this assumption will be correct often enough.
Obviously, you need to be on the main thread to use this.</div>
