Run a new UI background activity from an ANE (Adobe Native Extension) on Android

Question

I'm trying to make an Android ANE based on the YouTube API.

The YouTube API requires to start a new activity which when called through the ANE, disables the Air app activity until the user hits the back button.

What options do I have to run the YouTube activity in the background so that the Air app will stay interactive?

Activity Class:

/**


* A sample showing how to use the ActionBar as an overlay when the video is playing in fullscreen.
 *
 * The ActionBar is the only view allowed to overlay the player, so it is a useful place to put
 * custom application controls when the video is in fullscreen. The ActionBar can not change back
 * and forth between normal mode and overlay mode, so to make sure our application's content
 * is not covered by the ActionBar we want to pad our root view when we are not in fullscreen.
