在 Android 上使用 Google 登录时出现 Google 登录错误：状态代码：SIGN_IN_REQUIRED

Question

每次我尝试使用 Google API 登录时，都会收到以下错误。我的清单具有适当的权限，并且我确实相应地创建了我的凭据。所以我不知道问题是什么。同意屏幕也不会显示。

确保 Google 开发者控制台中应用程序的 SHA-1 签名证书指纹属于用于签署您正在测试的 APK 的同一密钥。

默认情况下，在编译调试版本时 Android Studio 使用自己的调试密钥。您可以通过右键单击应用程序并选择“打开模块设置”来更改它。转到“签名”选项卡并配置您在开发控制台中提到的相同密钥。之后导航到“构建类型”选项卡并选择您的签名配置。
