title: Activity events on startActivity
body: <p>Is there any event triggered on an activity when I call </p>
  
  <pre><code>startActivity("activity_id", myIntent);
  </code></pre>
  
  <p>If the Activity exists already.</p>
  
  <p>I pass a parameter to the activity via </p>
  
  <pre><code>i.putExtra("someID", someSerializableObject );  
  </code></pre>
  
  <p>and would like to call a method to refresh a WebView.</p>
  
  <p>Right now, the call on startActivity brings the activity in the foreground but the webview does not display what i want.</p>
