Question

此处的新手问题：我无法在Firebase App上保存数据。为什么？我正在使用Base64Custom来编码用户的电子邮件，但无法保存。我之前已经做过，但是现在可以了。

public class MainActivity extends AppCompatActivity {

    private EditText campoNome, campoEmail, campoSenha;
    private Button botaoCadastrar;
    private Usuario usuario;
    private FirebaseAuth autenticacao;


    @Override

        super.onCreate(savedInstanceState);

        botaoCadastrar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String textoNome = campoNome.getText().toString();
                String textoEmail = campoEmail.getText().toString();
                String textoSenha = campoSenha.getText().toString();

                //Validação do preenchimento dos campos.

                            usuario = new Usuario();
                            usuario.setNome(textoNome);
                            usuario.setEmail(textoEmail);
                            usuario.setSenha(textoSenha);
                            cadastrarUsuario();



                        }

    public void cadastrarUsuario(){
        autenticacao = ConfiguracaoFirebase.getFirebaseAutenticacao();
        autenticacao.createUserWithEmailAndPassword(usuario.getEmail(), usuario.getSenha())
                .addOnCompleteListener(this, new OnCompleteListener <AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {

                        if(task.isSuccessful() ){

                         // String idUsuario = Base64Custom.codificarBase64(usuario.getEmail());
                            String idUsuario = usuario.getEmail();
                          usuario.setIdUsuario(idUsuario);
                          usuario.salvar();
                           verificaUsuarioLogado();

                                Toast.makeText(MainActivity.this, "Usuário Salvo com Sucesso", Toast.LENGTH_SHORT).show();
                            finish();


                        }else {

                            String excecao = "";
                            try {
                                throw task.getException();
                            }catch ( FirebaseAuthWeakPasswordException e){
                                excecao = "Digite uma senha mais forte!";
                            }catch ( FirebaseAuthInvalidCredentialsException e){
                                excecao= "Por favor, digite um e-mail válido";
                            }catch ( FirebaseAuthUserCollisionException e){
                                excecao = "Este conta já foi cadastrada";
                            }catch (Exception e){
                                excecao = "Erro ao cadastrar usuário: "  + e.getMessage();
                                e.printStackTrace();
                            }

                            Toast.makeText(MainActivity.this, excecao, Toast.LENGTH_SHORT).show();

                        }

                    }
                });



    }


   public void verificaUsuarioLogado(){
        autenticacao =  ConfiguracaoFirebase.getFirebaseAutenticacao();
        if(autenticacao.getCurrentUser() !=null ) {
            startActivity(new Intent(this, TelaCadastro.class));
        }

   }


}

我正在使用Getters和setter返回数据，并且我创建了一个方法调用salvar来保存在数据库中。

package com.example.eefad.aplicaoteste.activity.model;

import com.example.eefad.aplicaoteste.activity.Config.ConfiguracaoFirebase;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.Exclude;

public class Usuario {

    private String idUsuario;
    private String nome;
    private String email;
    private String senha;

    public Usuario() {

    }

    public void salvar(){
        DatabaseReference firebase = ConfiguracaoFirebase.getFirebaseDatabase();
        firebase.child("usuarios")
                .child(this.idUsuario)
                .setValue(this);



    }

    @Exclude
    public String getIdUsuario() {
        return idUsuario;
    }

    public void setIdUsuario(String idUsuario) {
        this.idUsuario = idUsuario;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Exclude
    public String getSenha() {
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }
}

我不知道我在做什么错。我一直试图保存电子邮件，但是使用该结构似乎是不可能的。
