How can I call a non-static method in a child Activity of an ActivityGroup from the ActivityGroup?
<p>I think the easiest way to ask the question would be to demonstrate how my current workflow is set up first:</p>

<ol>
<li>There is a <code>TabHost</code> that has an <code>ActivityGroup</code> as one of its tabs</li>
<li>That <code>ActivityGroup</code> as an <code>Activity</code> in it that calls an external service that I have no control over.</li>
<li>The External Service has a callback function that kicks off <code>onActivityResult</code> in the <code>ActivityGroup</code> and <strong>NOT</strong> in the <code>Activity</code> that called the Service.  This is because in order to have even have the <code>onActivityResult</code> fire, I had to call <code>getParent().startActivityForResult(</code></li>
</ol>

<p>The problem is that I want 'stuff' to happen in the <code>Activity</code> that called the External Service (e.g. an <code>Alert Dialog</code>, a web service call etc).  </p>

<p>So, how can a call a non-static method in the child Activity from the <code>ActivityGroup</code>? Is this even possible?</p>
