<!-- This is a theme that will adjust itself depending on the API version.
The default definition is the safe one, using a theme that has always
been defined. Look at values-11/styles.xml for a variation that is
selected when the holographic theme is available. -->

<!-- Older platforms don't have Theme.Holo.DialogWhenLarge; we will define
our own wrapper theme that uses it only when running on the appropriate
platform version. On older platforms, we always use the generic
fullscreen theme, because they don't support some feature that help
in correctly laying out an activity as a dialog. -->
