title: Android Studio doesn't recognize my resource directory
body: <p>I've created an Android Resource Directory, which contains xml file with some menu changes. Whenever I trying to use MenuInflater, Android Studio doesn't recognize my directory, which is called the menu. I've already tried to rebuild the project, what should I do with it?</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu) {
      MenuInflater menuInflater = getMenuInflater();
      menuInflater.inflate(R.menu.note_add); &lt;- the "menu" is a directory, that is not being seen by android studio
      return super.onCreateOptionsMenu(menu);
  }
  </code></pre>
  
  <ul>
  <li>This directory is created in res folder.</li>
  </ul>
