title: openOptionsMenu() across android versions
body: <p>I have an app that's been designed with the titlebar hidden in all intents. I want to utilize Activity.openOptionsMenu() from a button. It works fine on 2.2 but when I run the app on honeycomb, calling openOptionsMenu() doesn't seem to work. Is there another way?</p>
  
  <p>onclick code here, if it matters. This is inside my mapview activity, extending MapView:</p>
  
  <pre><code>  OnClickListener ocl =  new OnClickListener()
    {
  
       @Override
       public void onClick (View v)
       {
          switch (v.getId ())
          {
             case R.id.b_options:
                                    Log.d (TAG, "options clicked");
                                    mymapview.this.openOptionsMenu ();
             break;
  
             case R.id.b_prev:
                                    Log.d (TAG, "prev clicked");
             break;
          }
  
       }
    };
  </code></pre>
