title: How to find popup window by ID/tag/...?
body: <p>I created an activity which shows popup window. After the activity is stopped the following message is printed to log:</p>

  </code></pre>
  
  <p>Thus I would like to dismiss the popup in onPause() method of the activity.</p>
  
  <p>Is there a way to get reference to all visible PopupWindows in activity? Something like:</p>
  
  <pre><code>@Override
  protected void onPause() {
      super.onPause();
      findPopupWithTag("MY_POPUP").dismiss(); // &lt;--- IS THERE A SIMILAR METHOD?
  }
  </code></pre>
  
  <p>I don't want to keep explicit reference to popup to keep my code clean and simple...</p>
