A style specifies a collection of properties that specify how a widget looks. A theme is a series of styles that are applied to an Activity. We'll make different styles for different versions of Android. We'll create styles to apply to single and multiple widgets. We'll cover inheriting styles, default themes, applying themes and much more.
