销毁活动后删除Auth Firebase用户

Question

I have an activity called ValidadorActivity, in this activity I do a sms validation, right after the user signs up.

The registration is done by the Firebase Auth but it is done before this validation, so I look for a way to delete the auth firebase registry when the user exits the validation screen without putting the Token that was sent by sms correctly.

@Override
    protected void onDestroy() {
        super.onDestroy();

        //Ao fechar completamente a tela de validação com o campo textValidacao nulo ou incorreto, o cadastro no autenticacao e no banco de dados sao apagados, para evitar o cadastro de usuarios não validados.

        String codigoDigitado = codigoValidacao.getText().toString(); //Pega o texto da caixa de texto

        if (! codigoDigitado.equals(tokenGerado)) {//Verifica se esse texto e igual

            user.delete().addOnCompleteListener(new OnCompleteListener<Void>() { //deleta o usuario no Auth
                @Override
                public void onComplete(@NonNull Task<Void> task) {

                    if (task.isSuccessful()) {//Testa para ver se funcionou

                        Log.i("Usuario deletado(auth)","Sim");


                    }else{

                        Log.i("Usuario deletado(auth)","Não");

                    }

                }
            });
}

This code is not running, I think the code is right. Any ideas or suggestions?

Answer 1

The onDestroy method only runs when the activity is destroyed by the system, which is seldom the same as when the user exits the activity.

You might want to look at onPause or onStop , and in general have a look at the Android activity lifecycle for when precisely you want the code to run.
