Answer 1

I had the same exact question and could not find the answer to this problem anywhere. I tried everything. I don't know why this works but I restarted my phone and it happened to fix everything. Super late but hope it helps for anyone else with the same problem.

Answer 2

In Your Manifest File Add The Following

In the <manifest> tag (at the end)

xmlns:tools="http://schemas.android.com/tools"

Then in the <application> tag (at the begining)

tools:replace="android:allowBackup"
android:allowBackup="false"
android:fullBackupContent="false"

just as @Doug Stevenson mentioned above firebase saves some data on the phone adding these tags will ensure that that does not happen... so when you uninstall the app and install it again it will clear all the data associated with the app.

Answer 3

Firebase Authentication will cache an authentication token for the user when they're signed in. This prevents having to authenticate every little interaction the user makes with other services provided by Firebase. This token gets automatically refreshed periodically, but until then, the SDK assumes that the token represents the user. You'll find that the token will expire after some time, or you can force the issue by uninstalling and reinstalling the app, or clearing its data.

Authentication works regardless of the contents of your Realtime Database. They are independent from each other, except where security rules limit access to the currently authenticated user.
