【问题描述】：

注册按钮无法正常工作，它给了我身份验证失败的祝酒词。似乎我的使用电子邮件和密码创建用户的字符串是正确的，但它仍然无法正常工作。

我能做什么？如果可以的话，请帮忙。

【参考方案1】：

当任务失败时，它包含一个解释失败原因的异常。记录此原因以了解有关问题原因的更多信息：

public void onComplete(@NonNull Task<AuthResult> task) 
    if (task.isSuccessful()) 

        addClassToFirebase();

        Intent intent = new Intent(signup.this, MainActivity.class);
        intent.putExtra("etsufn", ETname.getText().toString());
        startActivity(intent);


     else 
        // If sign in fails, display a message to the user.
        Toast.makeText(signup.this, "Authintication failed", Toast.LENGTH_SHORT).show();
        Log.e("AUTH", "Authentication failed", task.getException()); // ?
    

另请参阅Task class 的参考文档。

【讨论】：

2出现的异常：com.google.firebase.FirebaseException：发生内部错误。 [ CONFIGURATION_NOT_FOUND ]

嗯，这就是问题的根本原因。您是否已经搜索过异常？

好的，谢谢！
