/**
* This example illustrates a common usage of the FoldingDrawerLayout widget to
* add Folding Efect to DrawerLayout from 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>
