title: onCreateOptionsMenu is not called
body: <p>I have simple application.</p>
  
  <p>Here is MyActivity.java</p>
  
  <pre class="lang-java prettyprint-override"><code>public class MyActivity extends Activity {
      /**
       * Called when the activity is first created.
       */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          return super.onCreateOptionsMenu(menu);
      }
  }
  </code></pre>
  
  <p>And I don't really understand why method <code>onCreateOptionsMenu</code> is called on phone and is not called on tablet?</p>
