一、项目需求：

在项目中导入Google框架，Google相关功能可以正常使用。

二、功能实现：

1、首先下载Google框架GMS包，可以在The Open GApps Project网站下载。选择相关配置后下载即可，有些包比较大，下载需要耐心等待一下，最后翻墙下载会快一些。

2、由于本人使用的TV平台，Google版本需要使用手机版，不能使用TV版，因为TV版很多apk在Google商店中无法搜索到。修改mtv_core_hardware.xml文件，把TV版改成手机版。有多个路径：device/google/atv/permissions/tv_core_hardware.xml ，vendor/mediatek/common-tv/configs/mtv_core_hardware.xml，vendor/mediatek/proprietary_tv/open/common/preinstall/permission/mtv_core_hardware.xml

<?xml version="1.0" encoding="utf-8"?><permissions> <feature name="android.hardware.type.television" />  <feature name="android.hardware.screen.landscape" />  <feature name="android.hardware.usb.host" />  <library name="com.android.future.usb.accessory" file="/system/framework/com.android.future.usb.accessory.jar" />    <feature name="android.hardware.wifi" /> <feature name="android.hardware.wifi.direct" /> <feature name="android.hardware.ethernet" /> <feature name="android.software.app_widgets" /> <feature name="android.software.input_methods" /> <feature name="android.software.backup" />  <feature name="android.software.voice_recognizers" /> <feature name="android.software.cant_save_state" />  <feature name="nrdp.modelgroup" /></permissions>

3、由于Google GMS包比较大，打包会占用很大空间。所以分区需要加大，具体加多少需要根据自己打包的内容而定。修改文件device/mediatek/xxxxx/BoardConfig.mk

4、把下载好的GMS包放到目录下vendor/partner_gms/

编辑

5、在文件中添加Google编译：device/mediatek/xxxx/device.mk，添加以下代码即可。

#***************************************Google play************************************#add by jude for google play service$(call inherit-product-if-exists, vendor/partner_gms/products/gms_tv.mk)#***************************************Google play************************************

添加以上修改之后，编译出ROM之后可以正常打开Google商店等应用。

三、遇到问题：

在登录Google账号时，一直提示“您的账号未成功添加，请重试！”。遇到这问题时，一开始以为账号有问题，但在windows下可以正常使用。然后怀疑是不是apk版本问题，替换多版后还是无法解决。

四、解决方案：

1、在替换Google 商店、Google服务等apk后，发现还是一样的问题，排除apk版本问题。

2、通过修改权限也无法解决该问题。

3、最后发现跟设备认证有关，通过手动翻墙注册设备后，发现问题解决。为什么需要设备认证，官方解释如下。

编辑

4、手动认证可以，代码如何自动认证呢？方法如下就是需要修改fingerprint相关属性。首先修改build/make/core/Makefile文件中的BUILD_FINGERPRINT，BUILD_FINGERPRINT的格式是组合起来的。相关文件：buildmakecoreversion_defaults.mk

........................# The string 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)$$($(DATE_FROM_FILE) +%m%d%H%M) else BF_BUILD_NUMBER := $(file <$(BUILD_NUMBER_FILE)) endif#add by jude for google play_BRAND := MediaTek_PRODUCT := m7332_eu_DEVICE := m7332_eu#_BUILD_NUMBER := eng.$(shell echo $${BUILD_USERNAME:0:6}).$(shell $(DATE) +%Y%m%d.%H%M%S)BUILD_FINGERPRINT := $(_BRAND)/$(_PRODUCT)/$(_DEVICE):$(PLATFORM_VERSION)/$(BUILD_ID)/$(BF_BUILD_NUMBER):$(TARGET_BUILD_VARIANT)/$(BUILD_VERSION_TAGS)#BUILD_FINGERPRINT := $(PRODUCT_BRAND)/$(TARGET_PRODUCT)/$(TARGET_DEVICE):$(PLATFORM_VERSION)/$(BUILD_ID)/$(BF_BUILD_NUMBER):$(TARGET_BUILD_VARIANT)/$(BUILD_VERSION_TAGS)#add endendif# unset it for safety.BF_BUILD_NUMBER :=........................

然后还得修改systemcoreinitproperty_service.cpp文件中的property_derive_build_fingerprint函数，ro.build.fingerprint前面的内容需要跟BUILD_FINGERPRINT中的保持一致。

// If the ro.build.fingerprint property has not been set, derive it from constituent piecesstatic void property_derive_build_fingerprint() { std::string build_fingerprint = GetProperty("ro.build.fingerprint", ""); if (!build_fingerprint.empty()) { return; } const std::string UNKNOWN = "unknown"; build_fingerprint = "MediaTek";//GetProperty("ro.product.brand", UNKNOWN);//add by jude build_fingerprint += '/'; build_fingerprint += "m7332_eu";//GetProperty("ro.product.name", UNKNOWN); build_fingerprint += '/'; build_fingerprint += "m7332_eu";//GetProperty("ro.product.device", UNKNOWN); build_fingerprint += ':'; build_fingerprint += GetProperty("ro.build.version.release", UNKNOWN); build_fingerprint += '/'; build_fingerprint += GetProperty("ro.build.id", UNKNOWN); build_fingerprint += '/'; build_fingerprint += GetProperty("ro.build.version.incremental", UNKNOWN); build_fingerprint += ':'; build_fingerprint += GetProperty("ro.build.type", UNKNOWN); build_fingerprint += '/'; build_fingerprint += GetProperty("ro.build.tags", UNKNOWN); LOG(INFO) << "Setting property 'ro.build.fingerprint' to '" << build_fingerprint << "'"; std::string error; uint32_t res = PropertySet("ro.build.fingerprint", build_fingerprint, &error); if (res != PROP_SUCCESS) { LOG(ERROR) << "Error setting property 'ro.build.fingerprint': err=" << res << " (" << error << ")"; }}
