flExter中的PlatformException（sign_in_failed，Status {statusCode = DEVELOPER_ERROR，resolution = null}，null）错误[复制]

Question

这个问题在这里已有答案：

• Error: Status{statusCode=DEVELOPER_ERROR, resolution=null} 15个答案

我有一个应用程序，有一个卡和卡的列表，我保存firebase数据库中的文本和firebase存储中的图像。我想为我的应用实施google-sign-in。我添加了SHA1和SHA256，然后我按照this教程中的步骤实现了google登录。现在，当我点击登录时，我发现它不起作用（你可以在文件中看到）。我在3天内尝试了很多方法，我无法解决它！ here是我的所有代码。这是我的日志：

Answer 1

复制项目https://console.developers.google.com中的客户端的ID。

将ID粘贴到您的资源字符串Android项目最后添加.requestIdToken（getString（R.string.default_web_client_id））

GoogleSignInOptions gso = new GoogleSignInOptions
            .Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();

我希望它有所帮助:)
