Subject: My FireBase Database doesn't save information

help me, please. Now I am working on my project and I need save information about my users. I chose Realtime Database, but it doesnt work. I have an exception:"This email is already in use", through I insert new email. I use everything(google.json, SHA-1, SHA-256), but my signing up new users doesnt work correctly. My rules:

{
"rules": {
".read": true,
".write": true
}
}

My class Person:

public String name, email;

public User(){}

public User(String name, String email){
this.name = name;
this.email = email;
}
}

My FireBaseAuth, FireBaseDataBase:


private FirebaseAuth mAuth;
private FirebaseDatabase usersDataBase;

///


mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(@NonNull Task task) {
if(task.isSuccessful()){
User user = new User(username, email);

FirebaseDatabase.getInstance().getReference("Users")
.child(FirebaseAuth.getInstance().getUid())
.setValue(user).addOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(@NonNull Task task) {
if(task.isSuccessful()){
Toast.makeText(RegisterActivity.this, "Пользователь успешно добавлен", Toast.LENGTH_SHORT).show();

startActivity(new Intent(RegisterActivity.this, SigningActivity.class));
}
else{
Toast.makeText(RegisterActivity.this, "Произошла ошибка! Пожалуйста, попробуйте позже", Toast.LENGTH_SHORT).show();
}
}
});
}
else {
Toast.makeText(RegisterActivity.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
