I currently build PulseAudio with the ndk using a standalone tool chain
and that works great.

My plan there is to finish off writing a OpenSL sink to be able to run
PulseAudio from a service and using a android device as a PulseAudio
sound server. This way PulseAudio runs ontop of a regular android
system.

Last time i touched things i could build the whole chain without any
patching.

If anyone is interested my build script is available at:
