Firebase的新蜂，我正在尝试Firebase身份验证，并尝试检查用户是否已登录.代码:

A new bee to Firebase, I am trying out the Firebase Authentication and trying to check if user is logged-in. code:

null != mAuth.getCurrentUser();

尽管我未登录，但我启用了匿名登录，但这会返回 true ，我认为这可能是问题所在，但是当我检查时 mAuth.getCurrentUser().isAnonymous()我正在获取 false .

And this returns true though I am not logged in but I have enabled annonymous login and I thought that could be the issue but when I check mAuth.getCurrentUser().isAnonymous() I am getting false.

在IDE上检查 mAuth.getCurrentUser()会显示以下内容:

Inspecting mAuth.getCurrentUser() on the IDE shows this:

这里有什么方向吗?

推荐答案

我有一个类似的问题，那就是退出Firebase是不够的-它会再次自动登录.

I've had a similar issue and it was that signing out of Firebase is not enough - it will sign in automatically again.

还必须使用GoogleSignInApi退出:

It's necessary also to sign out using the GoogleSignInApi:

firebaseAuth.signOut(); Auth.GoogleSignInApi.signOut(apiClient);
