Question on Android Audio

[hopkins]

Hi,

I use UAPP and love it, and am curious to better understand what is "under the hood". Looking at this explanation on Android audio - https://source.android.com/devices/audio - I am curious to know what "layers" are being used by UAPP. Does it use Alsa, Oss ? 

Thanks
