Não consigo criar um token

AgendaInstanceIDService

package br.com.alura.agenda.firebase;

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class AgendaInstanceIDService extends FirebaseInstanceIdService{

    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d("token firebase", "Refreshed token: " + refreshedToken);

        // If you want to send messages to this application instance or
        // manage this apps subscriptions on the server side, send the
        // Instance ID token to your app server.
        enviaTokenParaServidor(refreshedToken);
    }

    private void enviaTokenParaServidor(String refreshedToken) {
    }

}

OBS:

extends FirebaseInstanceIdService, onTokenRefresh() e .getToken(). Estão marcados como depreciados.

Oi Nailson, tudo bem?

O arquivo google-services.json está dentro do módulo app do projeto? Se ele estiver, me envia o projeto para que eu consiga investigar o possível problema.

Caso contrário, vá no projeto via console do Firebase, baixe o arquivo pelas opções do projeto e adicione no diretório app.

Sobre a implementação, tiveram algumas modificações com o tempo, e nos exercícios explico o que foi modificado, confira.

Tudo bem sim Alex!

Aqui está o link do github https://github.com/NailsonFerreira/agenda-android-studio.git

Obrigado pela atenção! Parabéns pela didática!

Oi Nailson, falta apenas seguir os passos do exercício que linkei, pois em vídeo temos a implementação antiga que é compatível com a versão do vídeo. Agora você faz tudo pela classe FirebaseMessaingService. Dá uma olhada na explicação do exercício e principalmente no commit que indica as diferenças com a nova implementação.

Precisando de ajuda é só avisar. Muito obrigado pelo feedback! :)

Então, apliquei a nova implementação e segui até as instruções do fim da aula 2, mas a conexão com o firebase ainda não funciona :( Fiz o debug percebi que por algum motivo que ainda não descobri, a classe AgendaInstanceIDService e seus metodos não estão sendo chamados.

Oi Nailson, vi o seu código, tá faltando ajustar o action do service do FirebaseMessagingService, você ainda deixou assim <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> sendo que tem que deixar com esse outro action aqui <action android:name="com.google.firebase.MESSAGING_EVENT"/>

Passei o fim de semana quebrando a cabeça, mas agora finalmente posso avançar no conteúdo.

Mais uma vez Parabéns pela didática! Obrigado Alex!

Que bom que conseguiu Nailson! Muito obrigado pelo feedback hehe

Precisando de ajuda, pode contar com agente ;)

Bons estudos.
