-/**
- * A window feature at the top of the activity that may display the activity title, navigation
- * modes, and other interactive items.
- * <p>Beginning with Android 3.0 (API level 11), the action bar appears at the top of an
- * activity's window when the activity uses the system's {@link
- * android.R.style#Theme_Holo Holo} theme (or one of its descendant themes), which is the default.
- * You may otherwise add the action bar by calling {@link
- * android.view.Window#requestFeature requestFeature(FEATURE_ACTION_BAR)} or by declaring it in a
- * custom theme with the {@link android.R.styleable#Theme_windowActionBar windowActionBar} property.
- * <p>By default, the action bar shows the application icon on
- * the left, followed by the activity title. If your activity has an options menu, you can make
- * select items accessible directly from the action bar as "action items". You can also
- * modify various characteristics of the action bar or remove it completely.</p>
- * <p>From your activity, you can retrieve an instance of {@link ActionBar} by calling {@link
- * android.app.Activity#getActionBar getActionBar()}.</p>
- * <p>In some cases, the action bar may be overlayed by another bar that enables contextual actions,
- * using an {@link android.view.ActionMode}. For example, when the user selects one or more items in
- * your activity, you can enable an action mode that offers actions specific to the selected
- * items, with a UI that temporarily replaces the action bar. Although the UI may occupy the
- * same space, the {@link android.view.ActionMode} APIs are distinct and independent from those for
- * {@link ActionBar}.
- * <div class="special reference">
- * <h3>Developer Guides</h3>
- * <p>For information about how to use the action bar, including how to add action items, navigation
- * modes and more, read the <a href="{@docRoot}guide/topics/ui/actionbar.html">Action
- * Bar</a> developer guide.</p>
