Thank you, Erel.
I feel honored to have received your attention on this.
I'm a happy camper who, so far, has been able to execute every task successfully as I've tried to learn Basic4Android. Love the resouces.
As to my camera question. I think I understand the posts you've referred to, but in a perfect world, I want to go one further - e.g. audio too.
My Samsung Galaxy Note-2 will run two apps simultaneously - so if I could pre-connect two phones with Qic Video, or Tango, or some such 3rd party Audio+Video - already connected, already displaying audio and video from phone 'A' (in my original post) on the screen and speaker of phone 'B' (which is running my new b4a application) - and my app would control the visibility of 'Tango' (or other 3rd party app) to a user who clicks a button in MY app.
Recap.Summary of my vision:
1. I have a 'droid phone (A) at a remote location
2. I have another phone (B) in my hand running a new b4a application
3. From "intent" in my new b4a application, I launch 'Tango' (or other 3rd party app) which connects to remote phone (A) (also running 'Tango')
4. My new b4a application then 'hides' 'Tango' until I click a button on my local phone (B)
5. My new b4a application then shows 'Tango', streaming audio and video from phone (A) which was already connected.
Impossible?
(just a hint and I can work out the details using your excellent reference materials)
Thanks !
