title: Navigation Drawer Icon (ic_drawer) not showing
body: <p>I am implementing a navigation drawer for my app. Now it works perfectly except for one small glitch. When I set the Navigation Drawer Icon (ic_drawer) to replace the regular "HomeAsUp" caret icon, I still get the arrow. The Nav Drawer icon does not show. I have implemented every method that was on the android developers website. But it doesn't seem to work.</p>
  
  <p>Below is my code:</p>
  
  <pre><code>DrawerLayout mDrawerLayout;
  FrameLayout leftDrawer, rightDrawer, contentFrame;
  ActionBarDrawerToggle mDrawerToggle;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_home);
      initializeViews();
  }
  
  private void initializeViews() {
      // TODO Auto-generated method stub
      mDrawerLayout = (DrawerLayout) findViewById(R.id.mDrawerLayout);
      mDrawerToggle = new ActionBarDrawerToggle(this,
              mDrawerLayout, R.drawable.ic_drawer,
              R.string.drawer_open_content_desc,
              R.string.drawer_close_content_desc);
  
      getActionBar().setHomeButtonEnabled(true);
      getActionBar().setDisplayHomeAsUpEnabled(true);
  
      mDrawerLayout.setDrawerListener(mDrawerToggle);
  
      leftDrawer = (FrameLayout) findViewById(R.id.drawerLeft_frame);
      rightDrawer = (FrameLayout) findViewById(R.id.drawerRight_frame);
      contentFrame = (FrameLayout) findViewById(R.id.content_frame);
  }
  
  
  @Override
  protected void onPostCreate(Bundle savedInstanceState) {
      // TODO Auto-generated method stub
      super.onPostCreate(savedInstanceState);
      mDrawerToggle.syncState();
  }
  
  @Override
  public void onConfigurationChanged(Configuration newConfig) {
      // TODO Auto-generated method stub
      super.onConfigurationChanged(newConfig);
      mDrawerToggle.onConfigurationChanged(newConfig);
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.home, menu);
      return true;
  }
  
  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
      // TODO Auto-generated method stub
      if (mDrawerToggle.onOptionsItemSelected(item)) {
          return true;
      }
      return super.onOptionsItemSelected(item);
  }
  </code></pre>
