I just thought it might be interesting to share all the steps. This was on an amd_64 machine running Ubuntu 10.04 Lucid, almost bare bone (so you'll see some silly aptitude install's) and behind a proxy. Biggest hurdle was glib/gobject didnt have an Android.mk so I had to find one and frankenstenise it! :) Also thanks to Stefan <a href="http://lists.freedesktop.org/archives/gstreamer-android/2012-February/000165.html">http://lists.freedesktop.org/archives/gstreamer-android/2012-February/000165.html</a> for kindly pointing me to the right freedesktop git server ip :) .
