Disabling JACK in android compilation

Does anybody know how to completely disable jack while compiling AOSP (Master)?

I've always had problems with jack, so I've just always turned it off by adding ANDROID_COMPILE_WITH_JACK := false in BoardConfig.mk (when compiling CyanogenMod). I'm now compiling aosp and it just seems to ignore this command.

Note: I'm not really trying to solve any jack related issues I have, I'm trying to turn it off.

Solution

  • You can disable the JACK without to change any code.

    make ANDROID_COMPILE_WITH_JACK:=false

    Just do it when making the entire Android Project.

    The magic is in build/make/combo/javac.mk:

    ifndef ANDROID_COMPILE_WITH_JACK
# Defines if compilation with jack is enabled by default.
ANDROID_COMPILE_WITH_JACK := true
endif

    And build/make/core/config.mk:

    ifeq ($(ANDROID_COMPILE_WITH_JACK),true)
DEFAULT_JACK_ENABLED:=full
else
DEFAULT_JACK_ENABLED:=
endif

    And build/make/core/clear_vars.mk:

    LOCAL_JACK_ENABLED:=DEFAULT_JACK_ENABLED

    It also indicates why your modification in a local module is in vain.
