下面问题的描述不重要，想必每个公司都有它自己的一套客制化需求，主要是思路。
今天遇到个问题，就是订单的版本号对应不对，平常高通订单版本号都是在config.mk文件改写，找了很久没有头绪。后面直接在vendor（客制化，公司订单客制化需求在这下面）下搜索文件错误的订单版本号，搜索bash命令如下
grep -rni --include="*" --exclude-dir=out "错误订单版本号" ./
搜索到configwikoinfo.ini文件原来公司为Wiko的Unify，这个坑新接MR版本的我哪知道。原来fingerprint也是在这里面定义的（平常在buildinfo.sh文件里面），fingerprint固定的，我靠，MR与上一送测版本fingerprint一致，google是不会接受的直接打回来，差点背锅。
configwikoinfo.ini
#内部、外部版本号，产品名称、品牌等等，fingerprint
TCUSTOM_BUILD_VERNO_FR = ...
CUSTOM_BUILD_VERNO_FR = ...
INTERNAL_BUILD_VERNO_FR = ...
WIK_PRODUCT_MODEL_FR = ...
WIK_PRODUCT_NAME_FR = ...
WIK_PRODUCT_DEVICE_FR = ...
WIK_PRODUCT_BOARD_FR = ...
#fixed BUILD_FINGERPRINT build number line
WIK_BUILD_FINGERPRINT_FR = ...
然而这个文件又有什么用了，原来在另一个仓库下有一个bwc.mk文件
# check configwikoinfo.ini path
ifeq ($(strip $(SUB_PROJECT_NAME)),)
wik_config_path := vendor/tinno/${TARGET_PRODUCT}/${PROJECT_NAME}/unify/configwikoinfo.ini
else
wik_config_path := vendor/tinno/${TARGET_PRODUCT}/${PROJECT_NAME}/SUB_PROJECTS/${SUB_PROJECT_NAME}/unify/configwikoinfo.ini
endif
$(warning "wik_config_path = $(wik_config_path)")
result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys")
$(warning "-- build wiko area --")
由上bwc.mk文件可知得到configwikoinfo.ini文件路径，然后运行buildwiko.py脚本，传入全局参数

前几天刚学过一点python，发挥一点余热然后自行分析该脚本逻辑。脚本比较简单易懂
1.先拿出参数赋值到变量中
2.然后通过传进来参数路径解读configwikoinfo.ini文件
3.然后就是判断逻辑操作，组建字符串写入相应的文件中了。写入文件的输出路径显而易见，在本同脚本目录下
解读完脚本之后就会修改了，从逻辑上看，只要wik_build_fingerprint等于null，它就会根据产品信息和时间戳等信息生成fingerprint数值。前面已经提到了我的需求，不与上一版本的fingerprint一样。直接将onfigwikoinfo.ini的WIK_BUILD_FINGERPRINT_FR值注释，这样就解决了。之后还需要同意fingerprint。要求BUILD_NUMBER里面不包含android这个字符串，这也很简单注释掉BUILD_NUMBER = "android" + BUILD_NUMBER这条语句
bwc.mk除上面以外的还做了意见事情
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/du:system/vendor/wiko/du
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/fr:system/vendor/wiko/fr
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/id:system/vendor/wiko/id
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/my:system/vendor/wiko/my
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/th:system/vendor/wiko/th
PRODUCT_COPY_FILES += $(LOCAL_PATH)/unify/tools/BWC/vn:system/vendor/wiko/vn
把脚本生成的信息文件copy到Android手机system/vendor/wiko 目录下，以备手机读取其中的信息。
真正意义上了解了Python的用处与强大。
打完Patch跑GMS出现错误，Google对于GMS认证要求是不断更新，毫无疑问，项目越久要求越多
果然，跑玩一轮GMS准备修改fail，又下面这种情况
Hi SPMs & TLs
根据谷歌最新的BTS（谷歌从6月份才强制check BTS测试）测试通知，要求fingerprint里的时间戳版本号要和ro.build.version.incremental的值保持一致，我们当前很多项目因为不一致导致送测3PL被拒，各位请及时安排工程师进行check和修改
*理解了这种模式其实修改起来十分简单，首先查看buildinfo.sh文件 echo "ro.build.version.incremental=$BUILD_NUMBER" 由此可知，ro.build.version.incremental这个值是等于BUILD_NUMBER宏，具体值eng.android.{时间戳}，具体构造在build仓库脚本下，懒得看了。
*由上面那个buildwiko.py脚本可知，BUILD_NUMBER这个值不是取的Android项目整个宏，而是自己在脚本中构造的，部分代码如下：
(status, BUILD_NUMBER) = commands.getstatusoutput('date +%s -d \'+121 min\'')
刚开始这就让我十分头疼了，脚本代码生成的时间戳，毫无疑问不满足Google最新BTS测试通知，如何修改就从这个脚本入手了，首先如何取得这个宏，如何去得到呢？对这方面毫无经验
不过看到bwc.mk文件中
result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys"）
这段，我猜想$(PLATFORM_VERSION)这种就是取得Android项目中的宏，然后当做脚本参数传入其中，抱着这种猜想，试试。
result := $(shell ./vendor/tinno/requirement/wik_common/unify/tools/BWC/buildwiko.py "${wik_config_path}" "WIKO" "$(PLATFORM_VERSION)" "$(BUILD_ID)" "$(TARGET_BUILD_VARIANT)" "release-keys" "$(BUILD_NUMBER)")
就改成这样，然后依葫芦画瓢，在buildwiko.py中接收参数 BUILD_NUMBER = sys.argv[7] ，然后对这个自行改造 BUILD_NUMBER = BUILD_NUMBER[12:]，只截取时间戳的部分。既然BUILD_NUMBER是作为参数传入，就不需要自己在脚本中构造。build_wiko_config(config_file_path):函数中关于BUILD_NUMBER构造全部都删了。
