title: ActionbarSherlock does not include "overflow" section of Action Bar (on Android 2.1)
body: <p>I am developing <strong>Android 2.1 API 7</strong> app. To implement action bar, I am using <a href="http://actionbarsherlock.com/" rel="noreferrer">ActionbarSherlock</a> library.</p>
  
  <p>Everything goes fine with the <strong>sherlock</strong> library, I can implement action bar with it in my project with the following code.</p>
  
  <p><strong>res/menu/action_menu.xml</strong> :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
      &lt;item android:id="@+id/new_payment_1"
            android:title="@string/new_payment"       
            /&gt;    
  
      &lt;item 
            android:id="@+id/label_1"
            android:icon="@drawable/ic_launcher"
            android:showAsAction="always"/&gt;
  
      &lt;item 
            android:id="@+id/label_2"
            android:title="text2"
            android:showAsAction="always"/&gt;
  
      &lt;!-- overflow section of action bar --&gt;
      &lt;item android:title="title2"/&gt;
  
      &lt;item android:title="title3"/&gt;
  
      &lt;item android:title="title4"/&gt;
  
  &lt;/menu&gt;
  </code></pre>
  
  <p>In my <strong>Activity</strong> class:</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu) {
     MenuInflater inflater = getMenuInflater();
     inflater.inflate(R.menu.action_menu, menu);
     return true;
  }
  </code></pre>
  
  <p>I got action bar successfully with above code. No problem at all on Android 3.2 platform.</p>
  
  <p><strong>BUT the problem is</strong> if I run my app on <strong>Android 2.1</strong> platform, the action bar <strong>has no overflow section</strong> on the Action Bar. <strong>Why???</strong> Anyone has experienced the same problem when using <strong>Sherlock</strong> library on old Android platform??</p>
  
  <p>(P.S. "overflow section" of action bar is the right-most part of action bar which hides some items like a popup menu. <a href="http://developer.android.com/design/patterns/actionbar.html" rel="noreferrer">More info here</a> ) </p>
