Hi guys:
I have tried ani's suggestion. I modify the codec cpp file and
change all the read/write register function with fake action and it
does work.
Now I could bypass this issue and see the home screen.
on the other hand, using BOARD_USES_GENERIC_AUDIO also do not work
for me.....
ani, thanks a lot...
But the question is still exist: How to Build one mininum Android?
