Soong: Is it possible to read a conditional variable/feature flag defined in a device.mk file?

[Michael Lekman]

Hello,

Is it possible to access a feature flag set in a device setup mk file.

For example:
https://android.googlesource.com/device/lge/bullhead/+/master/device.mk#297

TARGET_USES_NANOHUB_SENSORHAL

Can we access it in a go file?

if ctx.AConfig().IsEnvTrue("TARGET_USES_NANOHUB_SENSORHAL") { cflags = append(cflags, "-DTARGET_USES_NANOHUB_SENSORHAL") }

I am trying to add a define and add a shared lib in my Android.bp file that are dependent on a conditional feature flag.

BR

It needs to be plumbed through to soong using build/make/core/soong_config.mk and build/soong/android/variable.go.
