Can an Application call methods directly on an Activity?
<p>We have an application:</p>

<pre><code>public class MyApplication extends Application {
...
}
</code></pre>

<p>containing a main Activity called Start, configured in AndroidManifest.xml  </p>

<p>MyApplication starts an AsyncTask, which loads data.   </p>

<p>When the AsyncTask returns, the Application wants to notify Start,<br>
but MyApplication seems to have no reference to Start.  </p>
