title: Use ic_drawer icon and application icon in ActionBar
body: <p>I am using a navigation drawer in my application but somehow the ic_drawer icon (the three stripes) is not showing up where it should. Since I am not able to post pictures yet, you may have a look on my Screenshot with the link:</p>
  
  <p><img src="https://i.stack.imgur.com/ASFaL.jpg" alt="ic_drawer icon"></p>
  
  <p>Furthermore I fail to make the application icon show up as well. I only accomplished to replace the drawer icon with my app icon but I want <strong>both</strong>.</p>
  
  <p>All in all I want my application to look like <a href="https://developer.android.com/design/media/navigation_drawer_indicator_big.png" rel="nofollow noreferrer">this example</a> from the Android Developer design guide.</p>
  
  <p>This method in the NavigationDrawerFragment (which is autoimplemented by AndroidStudio) sets up the icon I am able to see:</p>
  
  <pre><code>public void setUp(int fragmentId, DrawerLayout drawerLayout) {
          mFragmentContainerView = getActivity().findViewById(fragmentId);
          mDrawerLayout = drawerLayout;
  
          ...
  
          ActionBar actionBar = getActionBar();
          actionBar.setDisplayHomeAsUpEnabled(true);
          actionBar.setHomeButtonEnabled(true);
  
          // ActionBarDrawerToggle ties together the the proper interactions
          // between the navigation drawer and the action bar app icon.
          mDrawerToggle = new ActionBarDrawerToggle(
                  getActivity(),                    /* host Activity */
                  mDrawerLayout,                    /* DrawerLayout object */
                  R.drawable.ic_drawer,             /* nav drawer image to replace 'Up' caret */
                  R.string.navigation_drawer_open,  /* "open drawer" description for accessibility */
                  R.string.navigation_drawer_close  /* "close drawer" description for accessibility */
          ) {
              ...
          };
          // If the user hasn't 'learned' about the drawer, open it to introduce them to the drawer,
          // per the navigation drawer design guidelines.
          if (!mUserLearnedDrawer &amp;&amp; !mFromSavedInstanceState) {
              mDrawerLayout.openDrawer(mFragmentContainerView);
          }
  
          // Defer code dependent on restoration of previous instance state.
          mDrawerLayout.post(new Runnable() {
              @Override
              public void run() {
                  mDrawerToggle.syncState();
              }
          });
  
          mDrawerLayout.setDrawerListener(mDrawerToggle);
      }
  </code></pre>
  
  <p>Thanks for your help in advance!</p>
