title: Android DrawerLayout - openDrawer with Gravity.Start creates a lint error "Must be one or more of..."
body: <p>I have created a <code>DrawerLayout</code> and also have an <code>ImageView</code> (a 'hamburger') that opens it when clicked.<br>
  My problem is that when using the following code, a lint error is shown in AndroidStudio: <code>Must be one or more of: Gravity.LEFT, Gravity.RIGHT...</code>, there is no <code>Gravity.START</code> in there.  </p>
  
  <pre><code>ImageView openDrawerImageView = findViewById(R.id.open_drawer_image_icon);
  openDrawerImageView.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view) {
          drawerLayout.openDrawer(Gravity.START);
      }
  });
  </code></pre>
