问题 Good morning, I have this error when I try to register or login via my virtual device : E/StorageHelpers: Failed to turn object into JSON java.lang.NullPointerException: Attempt to invoke virtual method 'org.json.JSONObject com.google.firebase.auth.internal.zzm.zzbf()' on a null object reference at com.google.firebase.auth.internal.zzz.zzi(Unknown Source) at com.google.firebase.auth.internal.zzz.zzg(Unknown Source) at com.google.firebase.auth.FirebaseAuth.zza(Unknown Source) at com.google

问题 SITUATION: I am trying to check if my user is authenticated when he makes a request to the server. I googled a bit and found this: How to show different page if user is logged in via firebase So here's my try at implementing this solution using this library: https://github.com/js-cookie/js-cookie/blob/latest/src/js.cookie.js CODE: server-side var cookies = require("cookie-parser"); router.get("/", function(req, res, next){ const { token } = req.cookies; console.log('Verifying token', token);

问题 I'm trying to login from Facebook and Google API, the Google API works fine, the problem arises with Facebook login, everything is setup on the Facebook developers console and my app is live as well.

The complete code for that activity is: @Override protected void onCreate(Bundle

问题 I'm trying to retrieve the UID of the current logged-in firebase user in my Angular 4 app. Though, if I'm logging 'firebase.auth().currentUser' to the console I get a 'null'.

Though, I am, since I can read data from my database (my rules do not allow unauthenticated users),

In my app, I implemented onAuthStateChanged for client side js like below. firebase.auth().onAuthStateChanged((user) => { if(user) { //logged in } else { //do sth } }); After login, I confirmed this method will return actual user obj, but if I refresh the page, then user might be null. Curiously, sometimes user won't be null. I'm afraid there are some limitation of calling

问题 To delete a user from the authentication tab I am using this code: if let user = FIRAuth.auth()?.currentUser{ user.delete(completion: nil) } And this works just fine when the user signed-up with an e-mail/password combination but when they signed up with a social account they are NOT deleted and I can still see their email, UID etc in the Authentication tab. How can I delete those users from Firebase as well? Thanks in advance 回答1: To delete google and facebook user from firebase, you must

问题 I just upgraded Android Studio to version 2.2, I'm on the stable channel. I then adjusted the build.grade file by bumping the version of compile 'com.google.firebase:firebase-auth:x.x.x' to 9.4.0 , which is currently the latest version. After syncing the project I am no longer able to use import com.google.firebase.auth.AuthCredential; import com.google.firebase.auth.AuthResult; and import com.google.firebase.auth.FirebaseUser; The online docs for Firebase don't mention anything related to
