Android - Firebase Authentication not working with Email/Password setup

Question

So, I have my Firebase project setup, and all plugins that should be needed in the build.gradle (I quintuple checked). However, when I run my app and try to run the following method:

createUserWithEmailAndPassword(email, password)

It does not work and I constantly get something - which I will show below - in the log, and a notification manager popping up saying "Channel not found." I am not using a Notification Manager, but I believe it is done deep within the Android Runtime environment.

This method is called after the user types in the username and password in a GUI, and uses the method above to try to create a connection with my firebase project.

1-12 01:36:17.181 6593-6593/com.example.sarah.whosthere I/BiChannelGoogleApi: [FirebaseAuth: ] No Fallback module; NOT setting up for lazy initialization 
11-12 01:37:50.967 6593-6593/com.example.sarah.whosthere W/BiChannelGoogleApi: [FirebaseAuth: ] getGoogleApiForMethod() returned Gms
11-12 01:37:51.140 1681-3474/system_process E/NotificationService: No Channel found for pkg=com.example.sarah.whosthere, channelId=null, id=10436, tag=null, opPkg=com.example.sarah.whosthere, callingUid=10085, userId=0, incomingUserId=0, notificationUid=10085, notification=Notification(channel=null pri=0 contentView=null vibrate=null sound=null tick defaults=0x0 flags=0x110 color=0x00000000 vis=PRIVATE)

Also, in debug mode, during this method call I get a "no such instance field" error for my mAuth variable, which is set to an instance of FirebaseAuth. I tried looking this up, but what I have found and tried does not seem relevant towards my case.

If anyone has any reasons why this method would not be doing anything, I would appreciate the help as I have been banging my head against the wall for the past 4 hours trying to figure this out.

Thanks in advance.

UPDATE I got this working by changing the version from 11.6.0 down to 10.2.6 for all firebase services, including google play.

Answer 1

I have a similar problem when calling signInWithEmailAndPassword(). Not really an answer, but I think that this has come about since the upgrade to Firebase 11.6.0 Downgrading to 11.4.2 seems to remove the warning messages.

Answer 2

Had the same Issue here, after updating the Google Play Store it works like a charm. I hope it will work for you too

Answer 3

I had this problem as well. I found out that the emulator was offline for some reason, so i just closed the emulator and tried again.
