R.style

The default system theme. This is the theme used for activities that have not explicitly set their own theme.

You can count on this being a dark background with light text on top, but should try to make no other assumptions about its appearance. In particular, the text inside of widgets using this theme may be completely different, with the widget container being a light color and the text on top of it a dark color.

Special variation on the default theme that ensures the background is completely black. This is useful for things like image viewers and media players. If you want the normal (dark background) theme do not use this, use Theme.
