Thanks for your reply.
Our purpose is to generate "License checking code" for specific product
build.
So we have a shell script to generate the code based on the PRODUCT_XXX
properties.
Are you implying that Android.bp should only be used in generic (product
independent) modules?
And this kind of code should be put in device/product specific stuff and
use Android.mk to achieve the goal?
(P.S. will Android.mk be kept or will Android.bp take over the whole build?)
