FirebaseUser - Android - 获取登录提供程序

Question

Can anyone help me find the getloginproviders problem

public String getLoginProvider() throws Exception {
        FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
        if (firebaseUser != null)
            return firebaseUser.getProviders().get(0);
        else
            throw new Exception("Couldn't getMessage the provider");
    }

build output find this error

error: cannot find symbol
            return firebaseUser.getProviders().get(0);
                               ^
  symbol:   method getProviders()
  location: variable firebaseUser of type FirebaseUser

I don't know why the symbol . I used went into error

I am new to this. Hopefully someone can help.

Thank you!

As you can see from the API documentation, FirebaseUser doesn't have a method called "getProviders". Perhaps you meant to use getProviderData()
