问题
I used to create accounts and connect to my application with firebase but then soon when I disconnected I couldn't create accounts. After 1h of that, I managed to create an account and when I disconnected to see if the problem was resolved, I realize that it's still there.
By doing task.getException() in case of account creation failure, I get this error:
"com.google.firebase.FirebaseException: An internal error has occurred. [7:]"
Do you have an idea of the cause of the problem?
回答1:
I have same problem because my internet was not active. Make sure you have active internet connection.

I had a similar issue and got the same exception and code: 7. I was calling firebaseUser.getIdToken() in a Rx stream. So while testing the apps functionality while being offline, I found that the JWT token that is returned in firebaseUser.getIdToken() had expired and was throwing said error. It has a lifetime of 1h.
So I split out my implementation to separate functions, only calling firebaseUser.getIdToken() before a authorised call, which must be done while online anyway to be sure and secure.
Without seeing any code, it seems you are signed in/keep a reference to a expired firebase token. Make sure you signed out properly from firebaseAuth before calling your "account creation" piece.

If you are sure you have an active Internet connection and you are testing from an Emulator, restart your emulator and it should work. Sometimes, the emulator disconnects from the Internet and these sort of problems occur.
