private FirebaseAuth firebaseAuth;
private DatabaseReference userDatabaseRef;
private StorageReference userProfileImageRef;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_details);

    getSupportActionBar().setTitle("Set up you account");

    initialize();

    customProgressDialog = new CustomProgressDialog(this);

    firebaseAuth = FirebaseAuth.getInstance();
    currentUserId = firebaseAuth.getCurrentUser().getUid();
    userProfileImageRef = FirebaseStorage.getInstance().getReference().child("profile images");
    userDatabaseRef = FirebaseDatabase.getInstance().getReference().child("Users").child(currentUserId);

    )
)

同样的错误也出现在

    }
}

以下是我的问题

其实我做一个应用程序，如社会媒体，在这里我使用电话号码登录选项，让我的用户登录电话号码和存储他们的数据，如姓名，出生日期，性别，工作等数据库。
在初始化时一切都很好，甚至数据库也工作一切都正常，但当我在那里实现电话号码登录方法时，它需要一个名为PhoneAuthOptions的类，而这个类在firebase库中不可用。我在互联网上搜索错误，发现我应该使用firebase bom，当我使用这个时，它就这样做了，但它也犯了数据库错误。
我必须使用这两个库（电话号码登录，数据库）在我的应用程序

firebase

PhoneAuthOptions类存在于com.google.firebase.auth包中。因此，如果你想在Android应用中使用该依赖项，我建议你使用以下代码行：

implementation platform("com.google.firebase:firebase-bom:31.2.3")
implementation "com.google.firebase:firebase-auth-ktx"

对于其他Firebase服务，请添加以下依赖项：

implementation "com.google.firebase:firebase-database-ktx"
implementation "com.google.firebase:firebase-storage-ktx"

如果使用BOM，就不需要再指定版本了，如果使用Java，可以省略上面行中的-ktx。
