Android In/Out animated transitions without ViewFlipper
<p>So I have a ActivityGroup, and I would like to animate the transition between its child activities.  Right now I have a "slide in from left" animation in XML that I am loading via AnimationUtils.LoadAnimation.</p>

<p>However this just animates the incoming activity.  I would like to slide the current activity out on the left side simultaneously.  I have been able to accomplish this with a ViewFlipper, but for this project it doesn't make sense to use this method.</p>

<p>What are my options?</p>
