- * A utility class that helps with showing and hiding system UI such as the

- * Creating Backward-Compatible UIs</a> to ensure that devices running any
- * version of ndroid OS are supported. More specifically, there are separate
- * implementations of this abstract class: for newer devices,
- * {@link #getInstance} will return a {@link SystemUiHiderHoneycomb} instance,
- * while on older devices {@link #getInstance} will return a
- * {@link SystemUiHiderBase} instance.
- * <p/>
- * For more on system bars, see <a href=
