| 由于需要修改audio hal 所以需要重新编译 hardware/rockchip/audio/ 但是发现官方是直接copy的so ,经查找发现hardware/rockchip/audio/Android.mk中 AUDIO_FORCE_LEGACY=false 修改为 AUDIO_FORCE_LEGACY=true 可以编译 但是编译过程中报错： mmm hardware/rockchip/audio/ ============================================ PLATFORM_VERSION_CODENAME=REL PLATFORM_VERSION=10 TARGET_PRODUCT=rk3399_firefly_aio TARGET_BUILD_VARIANT=userdebug TARGET_BUILD_TYPE=release TARGET_ARCH=arm64 TARGET_ARCH_VARIANT=armv8-a TARGET_CPU_VARIANT=cortex-a53 TARGET_2ND_ARCH=arm TARGET_2ND_ARCH_VARIANT=armv7-a-neon TARGET_2ND_CPU_VARIANT=cortex-a15 HOST_ARCH=x86_64 HOST_2ND_ARCH=x86 HOST_OS=linux HOST_OS_EXTRA=Linux-5.10.16.3-microsoft-standard-WSL2-x86_64-Ubuntu-18.04.5-LTS HOST_CROSS_OS=windows HOST_CROSS_ARCH=x86 HOST_CROSS_2ND_ARCH=x86_64 HOST_BUILD_TYPE=release BUILD_ID=QD4A.200805.003 OUT_DIR=out ============================================ device/rockchip/rk3399/preinstall/preinstall.mk was modified, regenerating...
