What is "navigation-drawer"

The Navigation Drawer is a sliding panel, situated on the left side of the screen, used to display the application’s main navigation options.

Usually hidden, it can be revealed by sliding a finger over the left edge of the screen, in a left-to-right direction, or at the top level of the application by tapping the application icon.

To add a Navigation Drawer, use a Drawerlayout as root of layout.
Within the Drawerlayout, add to view containing the main content of the screen (the layout visible when the Navigation Drawer is hidden) and the view which contains the content of Navigation Drawer.

Example:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    <!-- The navigation drawer -->
    <ListView android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
