Thanks for your reply,Dan In fact, I want to know how to switch from makefile to soong in buliding stage exactly. As you said, the commond ,`lunch aosp_crosshatch-eng` ,aosp_crosshatch-eng is $1 for lunch command in envsetup.sh. But the next execute flow in that function : ` local choices=($(TARGET_BUILD_APPS= get_build_var COMMON_LUNCH_CHOICES))` Here we use COMMON_LUNCH_CHOICES again.Please note i did not want to edit ot use it directly. In such case, can we call COMMON_LUNCH_CHOICES as if it was the first time appear on the file? Bo
