I have 3 EditText. one for username, one for email, and the last for password. Once the user signs up, I want to send the username data to a specific firebase path. In firebase, I created a path called "usernames", I just need to send the value there. Is that possible? I need this so I can store all the usernames in one list, then check if the username is already in use.
here is my code:
