title: ActionBarDrawerToggle is not setting Drawer Indicator
body: <p>I am trying to add the navigation drawer in my app.. Everything is working fine But now I still got the arrow icon although I replaced it with the ic_drawer from Android? Here's my code:</p>
  
  <pre><code>private ActionBarDrawerToggle mDrawerToggle;
  
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
      ExpandableListView mDrawerList = (ExpandableListView) findViewById(R.id.left_drawer);
  
      mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
              GravityCompat.START);
      mDrawerList.setAdapter(new DrawerListAdapter(this));
      mDrawerList.setOnChildClickListener(new DrawerItemClickListener());
  
      mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
              R.drawable.ic_launcher, R.string.drawer_open,
              R.string.drawer_close);
  
      Log.d("Mudit",
              "mDrawerToggle" + mDrawerToggle.isDrawerIndicatorEnabled()); // returns true
  
      mDrawerLayout.setDrawerListener(mDrawerToggle);
  
      getActionBar().setDisplayHomeAsUpEnabled(true);
      getActionBar().setHomeButtonEnabled(true);
  
      getActionBar().setDisplayShowHomeEnabled(false);
  
  }
  
  /**
   * When using the ActionBarDrawerToggle, you must call it during
   * onPostCreate() and onConfigurationChanged()...
   */
  
  @Override
  protected void onPostCreate(Bundle savedInstanceState) {
      super.onPostCreate(savedInstanceState);
      mDrawerToggle.syncState();
  }
  
  @Override
  public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);
      mDrawerToggle.onConfigurationChanged(newConfig);
  }
  
  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
      if (mDrawerToggle.onOptionsItemSelected(item)) {
          return true;
      }
      return super.onOptionsItemSelected(item);
  }
