Thanks Steve!
I did the search before posting, but could not find anything like what I´m trying to do.
I think that the limitation of intents using ActivityStarter is that once that you launch the activity, you lose most control over it. I couldn´t find how to pause a youtube VIEW intent, for instance. Also I would like to keep control of the playing inside the AI2 app (play, pause, rewind X seconds).
Maybe it´s just something not supported. AI2 is great anyway!! :)
Best regards,
Bertu
