Doubts about android audio recording with gstreamer-android!

[daniel silva ferreira bruno]

Hi, all.
I liked to know if gstreamer-android can record all output audio in an android device (e.g., smartphone/tablet). If yes, then I liked to know if gstreamer-android can record output audio, from headphones/earphones, in an android device. If yes, for the two last questions, then I liked to know if it is valid for all android devices supported by gstreamer-android (with respect to the minimum android version, or the minimum android api version, required by gstreamer-android).
And, I liked to know if gstreamer-android can record audio, in background context, in an android device. 

Thanks for some future help.

Best Regards,Daniel S. F. Bruno.
