title: Exclude Toolbar from Shared Element Transition
body: <p>I would know how to do this, but I don't know the <code>Toolbar</code>'s ID. I'm using the <code>Toolbar</code> by default through the <code>Theme.AppCompat.Light.DarkActionBar</code> theme. Does it have a default ID in the support library, and if so what is it, and if not, is there any other way I can prevent the flicker that occurs during a transition?</p>
