title: How to: Multiple activities in a single view?
body: <p>Were looking into Android for writing a tablet based system.  Part of the design is for the system to be as modular as possible.  One aspect of this is to display any "STATUS" activities in a side view on the screen.  It looks like I can use PackageManager queryIntentActivities() to find the activities that show status information.  But, can I display these in a single view all at the same time (via a linear layout)?  The activities would be installed in separate apk's (features).</p>
  
  <p>Can this be accomplished using ActivityGroup?  Is this even allowed in Android?  Everything I've read implies that Activities take the whole screen or float on top.  This implies only one activity can be active at a time where as the design I'm thinking of uses the activities more like widgets. </p>
