+/**
+ * This example illustrates a common usage of the DrawerLayout widget
+ * in the Android support library.
+ *
+ * <p>A DrawerLayout should be positioned at the top of your view hierarchy, placing it
+ * below the action bar but above your content views. The primary content should match_parent
+ * in both dimensions. Each drawer should define a reasonable width and match_parent for height.
+ * Drawer views should be positioned after the content view in your layout to preserve proper
+ * ordering.</p>
+ *
+ * <p>When a navigation (left) drawer is present, the host activity should detect presses of
+ * the action bar's Up affordance as a signal to open and close the navigation drawer.
+ * Items within the drawer should fall into one of two categories.</p>
+ *
+ * <ul>
+ *     <li><strong>View switches</strong>. A view switch follows the same basic policies as
+ *     list or tab navigation in that a view switch does not create navigation history.
+ *     This pattern should only be used at the root activity of a task, leaving some form
+ *     of Up navigation active for activities further down the navigation hierarchy.</li>
+ *     <li><strong>Selective Up</strong>. The drawer allows the user to choose an alternate
+ *     parent for Up navigation. This allows a user to jump across an app's navigation
+ *     hierarchy at will. The application should treat this as it treats Up navigation from
+ *     a different task, replacing the current task stack using TaskStackBuilder or similar.
+ *     This is the only form of navigation drawer that should be used outside of the root
+ *     activity of a task.</li>
+ * </ul>
+ *
+ * <p>Right side drawers should be used for actions, not navigation. This follows the pattern
+ * established by the Action Bar that navigation should be to the left and actions to the right.
+ * An action should be an operation performed on the current contents of the window,
+ * for example enabling or disabling a data overlay on top of the current content.</p>

+/**
+ * This example illustrates a common usage of SlidingPaneLayout in the Android support library.
+ *
+ * <p>A SlidingPaneLayout should be positioned at the top of your view hierarchy, placing it
+ * below the action bar but above your content views. It is ideal as a two-pane layout
+ * for larger screens, used in place of a horizontal LinearLayout.</p>
+ *
+ * <p>What separates SlidingPaneLayout from LinearLayout in this usage is that SlidingPaneLayout
+ * allows these wide, two-pane layouts to overlap when horizontal space is at a premium. The user
+ * can then access both panes by physically sliding the content pane into view or out of the way
+ * or implicitly by moving focus between the two panes. This can greatly simplify development
+ * of Android apps that support multiple form factors and screen sizes.</p>
+ *
+ * <p>When it comes to your navigation hierarchy, the left pane of a SlidingPaneLayout is always
+ * considered to be one level up from the right content pane. As such, your Action Bar's
+ * Up navigation should be enabled if the right pane is obscuring the left pane, and invoking it
+ * should open the panes, revealing the left pane for normal interaction. From this open state
+ * where the left pane is in primary focus, the Action Bar's Up affordance should act as if
+ * both panes were fully visible in the activity window and navigate to the activity one level up
+ * in the app's logical hierarchy. If the activity is the root of the application's task, the up
+ * affordance should be disabled when the sliding pane is open and showing the left pane.
+ * This code example illustrates this root activity case.</p>
+ *
+ * <p>Note that SlidingPaneLayout differs in usage from DrawerLayout. While DrawerLayout offers
+ * sliding utility drawers for extended navigation options and actions, the panes of a
+ * SlidingPaneLayout are firmly part of the content itself. If it would not make sense for
+ * both panes to be visible all the time on a sufficiently wide screen, DrawerLayout and its
+ * associated patterns are likely to be a better choice for your usage.</p>

+/**
+ * This example illustrates a common usage of the DrawerLayout widget
+ * in the Android support library.
+ * <p/>
+ * <p>When a navigation (left) drawer is present, the host activity should detect presses of
+ * the action bar's Up affordance as a signal to open and close the navigation drawer. The
+ * ActionBarDrawerToggle facilitates this behavior.
+ * Items within the drawer should fall into one of two categories:</p>
+ * <p/>
+ * <ul>
+ * <li><strong>View switches</strong>. A view switch follows the same basic policies as
+ * list or tab navigation in that a view switch does not create navigation history.
+ * This pattern should only be used at the root activity of a task, leaving some form
+ * of Up navigation active for activities further down the navigation hierarchy.</li>
+ * <li><strong>Selective Up</strong>. The drawer allows the user to choose an alternate
+ * parent for Up navigation. This allows a user to jump across an app's navigation
+ * hierarchy at will. The application should treat this as it treats Up navigation from
+ * a different task, replacing the current task stack using TaskStackBuilder or similar.
+ * This is the only form of navigation drawer that should be used outside of the root
+ * activity of a task.</li>
+ * </ul>
+ * <p/>
+ * <p>Right side drawers should be used for actions, not navigation. This follows the pattern
+ * established by the Action Bar that navigation should be to the left and actions to the right.
+ * An action should be an operation performed on the current contents of the window,
+ * for example enabling or disabling a data overlay on top of the current content.</p>
