Libpulse-android is a JNI interface to functions of libpulse (which communicates with pulseaudio).
As of now, it is focused on providing access to introspection functions of the library, so as to enable writing of a remote control volume application (see my project Reverb on github)
I got... kind of lucky when I built libpulse for Android and realized I could start this project. If anyone can streamline and improve on this, and build libpulse again, I'd like to know! Preferrably, the newest version (I think this is sub-1.0, even) of the library.
