Not much since the last update, been planning on some more work coming month. Libventrilo still needs a bunch of changes done, also depending on the capabilities of AudioTrack, not sure if Android's audio system mixes multiple audiotrack streams...
We're an open source collaboration project so any assistance from some Java/Android gurus is always appreciated. I code mainly in C so my Java pretty much sucks
Progress can be tracked from our Trac page for the Android branch
. You will need the NDK to build libventrilo. And don't be afraid to drop by on IRC (Freenode, #mangler).
