1. 准备repo工具:
curl -L https://mirrors.tuna.tsinghua.edu.cn/git/git-repo > ~/bin/repo chmod a+x ~/bin/repo export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'2. 初始化仓库：
~/repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-16.0.0_r23. 同步代码：
~/repo sync -c -j84. 准备tv x86_64环境的 mk文件。代码里没有 x86_64的 mk，需要根据x86和其他x86_64的mk手动建立一个。
data/aosp/device/google/atv/products$ ls AndroidProducts.mk atv_logpersist.mk bootanimations aosp_tv_arm64.mk atv_lowram_defaults.mk gsi_tv_arm64.mk atv_mainline_system.mk gsi_tv_arm.mk aosp_tv_x86.mk atv_product.mk gsi_tv_base.mk atv_base.mk atv_system_ext.mk lowram_boot_profiles atv_emulator_vendor.mk atv_system.mk sdk_atv64_arm64.mk atv_generic_system.mk atv_vendor.mk sdk_atv_x86.mk首先拷贝aosp_tv_x86.mk，重命名为aosp_tv_x86_64.mk,把其中 x86的配置改成 x86_64的。

$(LOCAL_DIR)/aosp_tv_x86_64.mk 加到 AndroidProducts.mk里面。
5. 准备编译目标
source build/envsetup.sh lunch aosp_tv_x86_64-aosp_current-eng如果没有问题，会输出如下：
$ lunch aosp_tv_x86_64-aosp_current-eng 00:39:36 Build sandboxing disabled due to nsjail error. ============================================ PLATFORM_VERSION_CODENAME=REL PLATFORM_VERSION=16 TARGET_PRODUCT=aosp_tv_x86_64 TARGET_BUILD_VARIANT=eng TARGET_ARCH=x86_64 TARGET_ARCH_VARIANT=x86_64 TARGET_2ND_ARCH=x86 TARGET_2ND_ARCH_VARIANT=x86_64 HOST_OS=linux HOST_OS_EXTRA=Linux-6.8.0-88-generic-x86_64-Ubuntu-24.04.3-LTS HOST_CROSS_OS=windows BUILD_ID=BP2A.250605.031.A3 OUT_DIR=out SOONG_ONLY=false ============================================ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Wondering whether to use user, userdebug or eng? user The builds that ship to users.
