Extend Activity with MapActivity and ActivityGroup
<p>I'm new in Android.
How am I be able to extend an Activity with both MapActivity and ActivityGroup??</p>

<p>Because I need to display both a Map and a customized Tab on an Activty.</p>

<pre><code>public class MainActivity extends ActivityGroup implements MapActivity
</code></pre>

<p>Somehow I'm not allowed to do that.</p>
