title: WidgetID is not adding in android
body: <p>I have a class which extends <code>AppWidgetProvider</code>, and is responsible fro showing widget. 
  In my <code>onUpdate</code> method I initialize list of widgets add put all it id's in linked list.</p>
  
  <p>and I also have a method <code>updateWidget()</code> which is iterate through this linked list of widgets and update it every 10 seconds.
  So when I have one widget instance everything works great, but when I 'am trying to add several widget I got following problems:
  To add second widget to that linked list, I need first add it, then delete it, then add it again&lt; and only after that this widget id will be added to that linked list, so only after that it will be up-datable.</p>
  
  <p>What can be the issue, how can i get a normal workflow of my widget?
  Thank you on advance.</p>
