I want to know is adobe connect application built on adob air platform?
Are there any native extions used if it is built on air?
I believe it doe run on AIR.
What do you mean by native extensions? Do you mean objects you can load in the Share pod and have it work in the mobile app?
I know that you can load PPT(X), FLV, JPG, PNG, and MP3 file and they should display properly in the mobile app. MP4, F4V, and PDF may also work, but I'm not 100% sure on those.
I do know that SWF content does not currently work in the mobile app.
