The <em>app bar</em>, also known as the <em>action bar</em>, is one of the most
important design elements in your app's activities, because
it provides a visual structure and interactive elements that are familiar to
users. Using the app bar makes your app consistent with other Android apps,
allowing users to quickly understand how to operate your app and have a great
experience.
The key functions of the app bar
are as follows:
</p>
<ul>
<li>A dedicated space for giving your app an identity and indicating the
user's location in the app.
</li>
<li>Access to important actions in a predictable way, such as search.
</li>
<li>Support for navigation and view switching (with tabs or drop-down lists).
</li>
</ul>

This class describes how to use the
<a href="{@docRoot}tools/support-library/features.html#v7-appcompat">v7
appcompat</a> support library's {@link
android.support.v7.widget.Toolbar} widget as an app bar. There are other ways
to implement an app bar—for example, some themes set up an {@link
android.app.ActionBar} as an app bar by default—but using the appcompat
{@link android.support.v7.widget.Toolbar} makes it easy to set up an app bar
that works on the widest range of devices, and also gives you room to
customize your app bar later on as your app develops.
