firebase认证出现问题，使用android studio，代码未发送

Question

我在 firebase 项目中包含了 SHA1 和 SHA-256。

当片段运行时出现异常 Toast 消息：“此请求缺少有效的应用程序标识符，这意味着 SafetyNet 检查和 reCAPTCHA 检查均未成功。请重试，或检查 logcat 以获取更多详细信息”。

代码：

public class VerifyPhoneFragment extends Fragment {

    public static String source = null;
    PinView pinView;
    String phoneNo;
    boolean verified = false;
    private String VerificationCodSent;
    private String CodeEnteredByUser;

我遇到了同样的错误，我可以通过以下最后两个步骤解决它（确保你已经涵盖了所有这些）：

1. 在 Firebase 身份验证下的登录方法中启用电话选项
2. 确保在您的项目中下载并添加最新的 google-services.json 文件
3. 在https://console.cloud.google.com/中为您的 firebase 项目启用 Android 设备验证
4. 添加库实现“androidx.browser:browser:1.3.0” https://developer.android.com/jetpack..
