title: Android Navigation Drawer Implementation
body: <p>Previously, I used ImageButtons to navigate through Activities. Now I am going to make a standard Left Navigation Drawer. But the Application need to Extend Activity where as the Default Navigation includes Extend NavigationDrawerActivity. How to Handle this?
  I need something like:</p>
  
  <pre><code>public class Main extends Activity {
  
  //Bla Bla Bla
  
  }
  </code></pre>
  
  <p>And the Drawer Sample App already has this piece of cake:</p>
  
  <pre><code>public class Main extends ActionBarActivity implements 
  
      NavigationDrawerFragment.NavigationDrawerCallbacks {
  
          private NavigationDrawerFragment mNavigationDrawerFragment;
              //This and that
  
  
      }
  </code></pre>
