Adding dynamic widget to the PreferenceScreen of an AccountAuthenticator
<p>How can I have a "Preference" change visibility/appearance/text/etc. on the PreferenceScreen of an AccountAuthenticator?  Can't figure out how to attach to it.</p>

<p>I've tried AppWidget attached the "android:widgetLayout" tag without success (doesn't update).  </p>

<p>I know that I can write a custom "PreferenceScreen" that's launched off of the main PreferenceScreen through Intent, but how can I create controllable views/widgets that are contained within the AccountAuthenticator's main "PreferenceScreen"?</p>

<p>Thanks</p>
