/**
* 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>
