title: android widget id only for current widget
body: <p>Can I get my current widgetId inside <code>onUpdate()</code> method of <code>AppWidgetProvider</code>? </p>
  
  <p>I found many posts about sending <code>appWidgetId</code> in field of Intent, but I can't understand where I have to get it before sending.</p>
  
  <p>I didn't find the methods for getting only current widget Id without configuration activities.</p>
