Firebase not connecting about comp_quiz_android

Use small case letters along with some numbers to create a username, Also check in firebase if there is a user created when you tried for the first attempt and still you are trying to register using the same username,

Hi, I have tried small case letters with numbers as well small and big letter with numbers and without numbers but its giving same unique username error in. Database is empty no user created in it.

Just try to modify the logic for user sign-up where validation of a unique user is done. Try to come up with a logic of your own.
