为了通过google 的认证，我们需要修改fingerprint

ro.product.model (Model Name)	(型号名称)
ro.product.name (Product Name)	(产品名称)
ro.product.brand (Brand Name)	(品牌名称)
ro.product.device (Device Name)	(设备名称)
ro.product.manufacturer	(制造商名称)

公司做了MTK 和高通平台，总结下修改方法，以下都是基于Android 12平台

MTK 平台

首先找到这几个property 设置值的地方

build/make/core/sysprop.mk

define generate-common-build-props
    echo "####################################" >> $(2);\
    echo "# from generate-common-build-props" >> $(2);\
    echo "# These properties identify this partition image." >> $(2);\
    echo "####################################" >> $(2);\
    $(if $(filter system,$(1)),\
        echo "ro.product.$(1).brand=$(PRODUCT_SYSTEM_BRAND)" >> $(2);\
        echo "ro.product.$(1).device=$(PRODUCT_SYSTEM_DEVICE)" >> $(2);\
        echo "ro.product.$(1).manufacturer=$(PRODUCT_SYSTEM_MANUFACTURER)" >> $(2);\
        echo "ro.product.$(1).model=$(PRODUCT_SYSTEM_MODEL)" >> $(2);\
        echo "ro.product.$(1).name=$(PRODUCT_SYSTEM_NAME)" >> $(2);\
      ,\
        echo "ro.product.$(1).brand=$(PRODUCT_BRAND)" >> $(2);\
        echo "ro.product.$(1).device=$(TARGET_DEVICE)" >> $(2);\
        echo "ro.product.$(1).manufacturer=$(PRODUCT_MANUFACTURER)" >> $(2);\
        echo "ro.product.$(1).model=$(PRODUCT_MODEL)" >> $(2);\
        echo "ro.product.$(1).name=$(TARGET_PRODUCT)" >> $(2);\
    )\

这几个property 对应的值分别是

PRODUCT_MODEL　PRODUCT_BRAND　TARGET_DEVICE　PRODUCT_MANUFACTURER
 TARGET_PRODUCT

所以我们只要修改对应的宏就可以了

我们的修改方式是

build/make/core/Makefile

MY_BRAND="111111"
MY_MANUFACTURER="1111"
MY_DEVICE="1111"
MY_MODEL="11111"
MY_NAME="1111"


define generate-common-build-props
	PRODUCT_BRAND="$(MY_BRAND)" \
	PRODUCT_DEVICE="$(MY_DEVICE)" \
	PRODUCT_MANUFACTURER="$(MY_MANUFACTURER)" \
	PRODUCT_MODEL="$(MY_MODEL)" \
	PRODUCT_NAME="$(MY_NAME)" \
	$(call generate-common-build-props-with-product-vars-set,$(1),$(2))
endef

替换成

echo "ro.product.$(1).brand=$(MY_BRAND)" >> $(2);\
         echo "ro.product.$(1).device=$(MY_DEVICE)" >> $(2);\
         echo "ro.product.$(1).manufacturer=$(MY_MANUFACTURER)" >> $(2);\
         echo "ro.product.$(1).model=$(MY_MODEL)" >> $(2);\
         echo "ro.product.$(1).name=$(MY_PRODUCT)" >> $(2);\

整编生效

对应的fingerprint 如何修改呢，先看下原生的是的如何拼成的

build/make/core/sysprop.mk

echo "ro.$(1).build.fingerprint=$(BUILD_FINGERPRINT_FROM_FILE)" >> $(2);\
echo "ro.build.fingerprint=$(BUILD_FINGERPRINT_FROM_FILE)" >> $(2);\

# BUILD_FINGERPRINT is used used to uniquely identify the combined build and
# product; used by the OTA server.
ifeq (,$(strip $(BUILD_FINGERPRINT)))
  ifeq ($(strip $(HAS_BUILD_NUMBER)),false)
    BF_BUILD_NUMBER := $(BUILD_USERNAME)$$($(DATE_FROM_FILE) +%m%d%H%M)
  else
    BF_BUILD_NUMBER := $(file <$(BUILD_NUMBER_FILE))
  endif
  #BUILD_FINGERPRINT := $(PRODUCT_BRAND)/$(TARGET_PRODUCT)/$(TARGET_DEVICE):$(PLATFORM_VERSION)/$(BUILD_ID)/$(BF_BUILD_NUMBER):$(TARGET_BUILD_VARIANT)/$(BUILD_VERSION_TAGS)
  BUILD_FINGERPRINT := $(PRODUCT_BRAND)/$(TARGET_PRODUCT)/$(TARGET_DEVICE):$(PLATFORM_VERSION)/$(BUILD_ID)/$(BUILD_NUMBER_EXTERNAL):$(TARGET_BUILD_VARIANT)/$(BUILD_VERSION_TAGS)
endif
# unset it for safety.
BF_BUILD_NUMBER :=

BUILD_FINGERPRINT_FILE := $(PRODUCT_OUT)/build_fingerprint.txt
ifneq (,$(shell mkdir -p $(PRODUCT_OUT) && echo $(BUILD_FINGERPRINT) >$(BUILD_FINGERPRINT_FILE) && grep " " $(BUILD_FINGERPRINT_FILE)))
  $(error BUILD_FINGERPRINT cannot contain spaces: "$(file <$(BUILD_FINGERPRINT_FILE))")
endif
BUILD_FINGERPRINT_FROM_FILE := $$(cat $(BUILD_FINGERPRINT_FILE))
# unset it for safety.
BUILD_FINGERPRINT :=

注意看BUILD_FINGERPRINT　的生成规则，既然我们要生成自己的fingerprint

只要替换成自己上面自己的PRODUCT INFO 就可以了，抄google 的作业

ifeq (,$(strip $(MY_FINGERPRINT)))
MY_FINGERPRINT := $(MY_BRAND)/$(MY_NAME)/$(MY_DEVICE):$(PLATFORM_VERSION)/$(BUILD_ID)/$(BUILD_NUMBER_FROM_FILE):$(TARGET_BUILD_VARIANT)/$(BUILD_VERSION_TAGS)
endif
MY_FINGERPRINT_FILE := $(PRODUCT_OUT)/my_fingerprint.txt
ifneq (,$(shell mkdir -p $(PRODUCT_OUT) && echo $(MY_FINGERPRINT) >$(PRODUCT_OUT)/my_fingerprint.txt ))
  $(error MY_FINGERPRINT cannot contain spaces: )
endif
MY_FINGERPRINT_FROM_FILE := $$(cat $(MY_FINGERPRINT_FILE))

然后把BUILD_FINGERPRINT_FROM_FILE　替换成　MY_FINGERPRINT_FROM_FILE　　OK

Release key

修改release key 路径

MTK 原生的release key 逻辑好复杂呀，小伙伴们瞅瞅

device/mediatek/common/device.mk
device/mediatek/vendor/common /device.mk
device/mediatek/system/common /device.mk

#我自己加的
PRODUCT_DEFAULT_DEV_CERTIFICATE := build/target/product/security/releasekey
＃MTK的逻辑
#ifdef SYS_TARGET_PROJECT
#ifndef MTK_TARGET_PROJECT
#ifneq ($(wildcard $(strip $(SYS_TARGET_PROJECT_FOLDER))/security),)
#  PRODUCT_DEFAULT_DEV_CERTIFICATE := $(strip $(SYS_TARGET_PROJECT_FOLDER))/security/releasekey
#else ifneq ($(wildcard device/mediatek/security),)
#  PRODUCT_DEFAULT_DEV_CERTIFICATE := device/mediatek/security/releasekey
#else
#  ifeq ($(MSSI_MTK_SIGNATURE_CUSTOMIZATION),yes)
#    ifeq ($(wildcard device/mediatek/security/$(strip $(SYS_TARGET_PROJECT))),)
#      $(error Please create device/mediatek/security/$(strip $(SYS_TARGET_PROJECT))/ and put your releasekey there!!)
#    else
#      PRODUCT_DEFAULT_DEV_CERTIFICATE := device/mediatek/security/$(strip $(SYS_TARGET_PROJECT))/releasekey
#    endif
#  else
##   Not specify PRODUCT_DEFAULT_DEV_CERTIFICATE and the default testkey will be used.
#  endif
#endif
#endif
#endif

上面注释掉的部分就是MTK 的逻辑，看的晕乎乎的，他们这么做的原因大概是为了通用其他项目，我只保留上面一段release key 的路径，咱又不需要适配哈哈．注意上面两个路径都要改．

生成自己的key

知道了release key 路径，下面就要想办法替换了

先生成自己的，生成方式，google 已经在代码里面告诉我们了．参考下面README

build/make/target/product/security/README

android device monitor 下载 device info android_SYS

需要生成我们自己的release key ,方法同上

development/tools/make_key releasekey  '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'

把生成的key ,copy 到PRODUCT_DEFAULT_DEV_CERTIFICATE　对应的路径可以

记得修改权限

chmod 664 releasekey.pk8
chmod 664 releasekey.x509.pem

通过下面命令生成4个key

subject='/C=ZH/ST=SH/L=ODM/O=ODM/OU=ODM/CN=ODM/emailAddress=odm@odm.com'
for x in releasekey platform shared media testkey; do ../../../../../development/tools/make_key $x "$subject"; done

修改fingerprint

build/make/core/Makefile
ifeq ($(DEFAULT_SYSTEM_DEV_CERTIFICATE),build/target/product/security/releasekey)
BUILD_KEYS := release-keys
endif

/build/core/sysprop.mk 这里面也要加，不然fingerprint 后面会出现releasekey,testkey 这种怪怪的问题

高通平台

高通平台和MTK 类似，不过高通平台分qssi和vendor 两套代码，所以改的时候有需要注意下，不能改漏了

修改release key,注意生成的release key ，需要在vendor 下source /launcher 自己项目的名称，同时copy 一份到qssi目前下

Vendor 修改路径：

vendor/qcom/项目名/项目名字.mk
 PRODUCT_DEFAULT_DEV_CERTIFICATE := build/make/target/product/security/releasekeybuild / core/Makefile
ifeq ($(DEFAULT_SYSTEM_DEV_CERTIFICATE),build/make/target/product/security/releasekey)
 BUILD_KEYS := release-keys
 endifbuild / core/Makefile

参考MTK 平台修改device info

build / tools/buildinfo_common.sh

修改生成的规则即可生效

echo "ro.${partition}.build.fingerprint=$MY_FINGERPRINT"

Qssi 修改路径

device/qcom/qssi/qssi.mk
PRODUCT_DEFAULT_DEV_CERTIFICATE := build/make/target/product/security/releasekey
build/core/sysprop.mk
ifeq ($(DEFAULT_SYSTEM_DEV_CERTIFICATE),build/make/target/product/security/releasekey)
 BUILD_KEYS := release-keys
 endiffingerprinter 修改成功，编译后可通过，查看下面文件看看是否生效
out/target/product/qssi/build_fingerprint.txt
qti/qssi/qssi:11/RKQ1.210614.002/xxxx:userdebug/release-keys
adb shell getprop | grep finger 查看finger 是否设置正确．
