编译Android 16 TV模拟器(一）

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'
初始化仓库：

~/repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-16.0.0_r2
同步代码：

~/repo sync -c -j8
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。

复制代码

endif

PRODUCT_NAME := aosp_tv_x86
PRODUCT_DEVICE := generic_x86
PRODUCT_BRAND := Android
PRODUCT_MODEL := AOSP TV on x86

修改之后的 aosp_tv_x86_64.mk:

复制代码

PRODUCT_NAME := aosp_tv_x86_64
PRODUCT_DEVICE := generic_x86_64
PRODUCT_BRAND := Android
PRODUCT_MODEL := AOSP TV on x86_64

然后把

$(LOCAL_DIR)/aosp_tv_x86_64.mk 加到 AndroidProducts.mk里面。

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：

复制代码

$ lunch aosp_tv_x86_64-aosp_current-eng

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  Wondering whether to use user, userdebug or eng?

  user        The builds that ship to users. Reduced debugability.
  userdebug   High fidelity to user builds but with some debugging options
              enabled. Best suited for performance testing or day-to-day use
              with debugging enabled.
  eng         More debugging options enabled and faster build times, but
              runtime performance tradeoffs. Best suited for day-to-day
              local development when not doing performance testing.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

如果没有改好，可能会输出如下：
