Question

我不知道这里会出现什么问题。我想知道用户是否匿名登录。我使用signInAnonymously()进行登录。一切都像魅力一样。但是对FirebaseAuth.getInstance().getCurrentUser().isAnonymous()的调用总是返回false。我在firebase控制台中验证了用户ID实际上是匿名的。这里可能出现什么问题？

：编辑： 更新的代码 - 为配置文件更新添加的代码 - 为匿名用户初始化添加的代码

public final void initiateAnonymousSignIn(@NonNull final String displayName, @Nullable final Bitmap avatar) {
    onRegistrationProgressStarted();

    Task<AuthResult> signInTask = FirebaseAuth.getInstance().signInAnonymously();
    signInTask.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if (task.isSuccessful()) {
                AuthResult result = task.getResult();
                FirebaseUser user = result != null ? result.getUser() : null;
                if (user != null) {
                    Log.d(getTag(), "Signed in anonymous user is "
                            + (user.isAnonymous() ? "anonymous." : "not anonymous."));
                }
                UserService.isLoggedInWithAnonymousUser();

                onRegistrationProgressFinished(true, null, AuthProvider.ANONYMOUS, displayName, avatar);
            } else {
                // Wrap FirebaseExceptions for better error handling.
                onRegistrationProgressFinished(false, wrapFirebaseException(task.getException(), null),
                        AuthProvider.ANONYMOUS, displayName, avatar);
            }
        }
    });
}

public void initiateUserAfterRegistration(@Nullable final String newDisplayName, @Nullable final Bitmap newAvatar) {
    final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

    if (user == null) {
        onUserLoadingFinished(null, DatabaseError
                .fromException(new Exception("Can't initiate user after registration. User is not signed in.")));
        return;
    }

    if (newDisplayName != null) {
        Task<Void> updateTask = updateProfile(user, newDisplayName);
        updateTask.addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                // proceed anyway, no matter if the profile could be updated or not
                loadUserAndUpdateOrCreateIfNeeded(newDisplayName, newAvatar);
            }
        });
    } else {
        loadUserAndUpdateOrCreateIfNeeded(null, newAvatar);
    }
}

个人资料更新：

private Task<Void> updateProfile(@NonNull FirebaseUser user, @NonNull final String displayName) {
    UserProfileChangeRequest profileChangeRequest =
            new UserProfileChangeRequest.Builder().setDisplayName(displayName).build();
    Task<Void> updateTask = user.updateProfile(profileChangeRequest);
    updateTask.addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if (task.isSuccessful()) {
                Log.i(TAG, "User profile updated successfully with new display name: " + displayName);
            } else {
                Log.w(TAG, "Could not update user profile with new display name.", task.getException());
            }
        }
    });

    return updateTask;
}

UserService.java

public class UserService {

    public static boolean isLoggedInWithAnonymousUser() {
        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

        if (user != null) {
            Log.d(TAG, "Current user is " + (user.isAnonymous() ? "anonymous." : "not anonymous."));
        } else {
            Log.d(TAG, "Current user is null.");
        }

        return user != null && user.isAnonymous();
    }

}

这是我得到的意外输出：

请注意登录后更新显示名称和之后的非匿名用户（在日志末尾）。这可能是个人资料更新后匿名状态不同步的错误吗？

FirebaseUser.isAnonymous（）在配置文件更新后始终返回false（Firebase 10.2.0）
