why HitTestResult.getType() retuns UNKNOWN_TYPE
<p>Why <em>HitTestResult.getType()</em> retuns <strong>UNKNOWN_TYPE</strong> in Android OS 2.2?  </p>

<p><strong>edit:</strong></p>

<pre><code>WebView.HitTestResult hr = ((WebView)v).getHitTestResult();
            if(hr!=null){
            if(hr.getType()==HitTestResult.EDIT_TEXT_TYPE)
                ((Activity) context).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
</code></pre>
