+/**
+ * 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>
