这里假设我们的公司名叫果冻（Jelly），我们准备开发一款对标苹果 14 的手机，取名叫 大米14（Rice14）。

接下来我们在源码中添加我们自己的产品（Product）

在 device 目录下添加如下的目录与文件：

Jelly/
└── Rice14├── AndroidProducts.mk├── BoardConfig.mk└── rice14.mk

BoardConfig.mk 包含了硬件芯片架构配置，分区大小配置等信息这里我们直接使用 aosp_x86_64 的BoardConfig.mk 就行。
BoardConfig.mk 拷贝自 build/target/board/generic_x86_64/BoardConfig.mk

# x86_64 emulator specific definitions
TARGET_CPU_ABI := x86_64
TARGET_ARCH := x86_64

WIFI_DRIVER_FW_PATH_PARAM   := "/dev/null"
WIFI_DRIVER_FW_PATH_STA     := "/dev/null"
WIFI_DRIVER_FW_PATH_AP      := "/dev/null"

rice14.mk 拷贝自 build/target/product/aosp_x86_64.mk

其中的 if 语句需要注释掉，同时需要修改最后四行

PRODUCT_USE_DYNAMIC_PARTITIONS := true# The system image of aosp_x86_64-userdebug is a GSI for the devices with:

# - compatible property override enabled# This is a build configuration for a full-featured build of the

PRODUCT_COPY_FILES += \system/core/rootdir/init.zygote32_64.rc:root/init.zygote32_64.rc# Overrides
# 修改产品名
PRODUCT_BRAND := Jelly
PRODUCT_NAME := rice14
PRODUCT_DEVICE := rice14
PRODUCT_MODEL := Rice14

AndroidProducts.mk 内容如下：

PRODUCT_MAKEFILES := \$(LOCAL_DIR)/rice14.mkCOMMON_LUNCH_CHOICES := \rice14-eng \rice14-userdebug \rice14-user \

最后验证：

source build/envsetup.sh
lunch rice14-eng
make -j16
emulator
