Thanks -- but I'm not sure what you're suggesting. I don't see a startActivity(Activity,Class) in the docs. If I'm missing it or the signature's different, when are you suggesting I call it? After the OS launches a second instance of my root Activity on top of the browser? I could see this working if I could transmit the Intent that second instance is passed back to the first instance *and* if I could then force that instance to come to the front (on top of the task the browser's in that the user's interacting with). But I've tried that already -- calling into the first instance via private methods -- but am stuck on how to bring it to the front. Android doesn't want me to do that, so I keep thinking there has to be an easier way to do this, one that the APIs anticipate.
