User registration fails with Firebase in Android

Can you help me understand why this class does not refrain the user? In practice, when I enter email, password, etc. then I click on registration gives me that the user has not been registered, how can I do?

    public void singUpUser(final String email , final String password, final String nickName, final String confermaPassword) {

        final ProgressDialog dialog = new ProgressDialog(mContext);
        dialog.setMessage("Stiamo registrando l'utente....");
        dialog.setCancelable(false);
        dialog.show();

        mAuth.signInWithEmailAndPassword(email,password)
                .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            Log.d(TAG, "crearUterWithEmail:Success");
                            dialog.dismiss();
                            Map<String,Object> creaUtente = new HashMap<>();
                            creaUtente.put("email", email);
                            creaUtente.put("password", password);
                            creaUtente.put("nickName", nickName);
                            creaUtente.put("confermaPassword", confermaPassword);
                            mDatabase.child("Utente").child(task.getResult().getUser().getUid()).updateChildren(creaUtente);

                            Intent intent = new Intent(mContext, activity_singIn.class);
                            mContext.startActivity(intent);
                        } else {
                            dialog.dismiss();
                            // If sign in fails, display a message to the user.
                            Log.w(TAG, "crearUterWithEmail:failure", task.getException());
                            Toast.makeText(mContext, "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();

                        }
                    }
                });
    }
    }

When you're getting the following error:

There is no user record corresponding to this identifier. The user may have been deleted.

Most likely means that you're trying to use the credentials of a user that doesn't exist in Firebase authentication anymore. A possible reason would be, that you deleted it.

To solve this, you have to create the user again, using createUserWithEmailAndPassword() and right after that try to sign in using signInWithEmailAndPassword().
