无法解决符号'default_web_client_id'错误，但应用程序成功运行

Question

我尝试删除并重新导入新的google-service.json文件。如您所见，Build和Logcat中没有错误，构建后App中也没有任何问题。

但是红线显示在下方

  

default_web_client_id

为

  

无法解析符号“ default_web_client_id”

尝试排除各种META_INF，迁移到AndroidX，生成SHA证书指纹和WebKey后重新下载Json文件，使缓存/重启无效。

此错误是由于删除了您的客户端ID（default_web_client_id）

-project-> app-> build->生成-> res-> google services->调试-> values-> values.xml

您必须在

中手动添加此字符串值

android-> app-> res-> values->字符串（例如从FIREBASE控制台开始）

<string name="default_web_client_id" translatable="false">237047375768-ma9cm63bn9goidlu99jl3fen5f6mieru.apps.googleusercontent.com</string>
