Has anyone tried demonstratating android + bluetooth on beagle board with embinux port?

I am able to pair a bluetooth headset using the bluetooth dongle on
command prompt. When tried streaming a wav file using the alsa_aplay
command to the bluetooth device, i got the following error :

ALSA lib external/alsa-lib/src/pcm/pcm.c:2161:(snd_pcm_open_conf)
Cannot open shared library /system/usr/lib/alsa-lib/
aplay: main:590: audio open error: No such file or directory

When further investigated "libasound_module_pcm_bluetooth.so" (shared
library) is not generated by the android build at all. This file gets
generated from the folder extrenal/bluez/utils/audio folder.
I would like to add this to android build system in external/bluez/

Please help/teach me in doing so of configuring the android make file
for this shared library since i am newbie to android makefile.

Thanks and regards,
