title: Widget launching a second instance of application
body: <p>I am having problems launching my application from my widget when it's clicked upon.
  Here is a cut of some code</p>
  
  <pre><code>// Create an Intent to launch activity
  Intent intent = new Intent(context, Entry_MainTabView.class);
  PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);             
  updateViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);
  </code></pre>
  
  <p>Now take the scenario.
  I launch my app, exit to the home page , then click on my widget.
  It launches a second instance of the application, so when I hit "back" , the application goes away and reveals the other copy. I then hit back again and finally go back to the homescreen.</p>
  
  <p>How can I make the Intent only create a new instance if none already exists in ram ?</p>
