title: Android widget, distinguish if onUpdate triggered by periodical or click update?
body: <p>I'm implementing a simple widget that updates periodically and by clicking it, no problem so far.</p>
  
  <p>I would however like the widget to behave slightly different if updated by the periodic timer or by clicking it.</p>
  
  <p>But I cant figure out how to distinguish if </p>
  
  <pre><code>onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds)
  </code></pre>
  
  <p>gets triggered by periodic timer set by <code>updatePeriodMillis</code> or by the click <code>PendingIntent</code>.</p>
  
  <p>Is this possible or does my question not make any sense?</p>
  
  <p>Thanks!</p>
