Question

我有以下代码：

firebaseAuth.createUserWithEmailAndPassword(email, senha)
    .addOnCompleteListener(CadastroActivity.this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful()) {
                Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
                Log.i("SuccessInCreateUser", task.getException().toString());
            }
            else{
                Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show();
                Log.i("ErrorInCreateUser", task.getException().toString());
            }
        }
    });

当我执行应用程序时，用户是按预期创建的，但它从未通过onComplete方法，我做错了什么？

我认为没有必要将task.isSuccesful（）放在已经onComplete（）回调中。会要求您尝试以下代码段：

firebaseAuth.createUserWithEmailAndPassword(email, senha)
            .addOnCompleteListener(CadastroActivity.this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
                Log.d("SuccessInCreateUser", "No exception");
                   if (!task.isSuccessful()) {
                    Log.w(TAG, "onComplete: Failed=" + task.getException().getMessage());

                    //Catch specific exception here like this. Below is the example of password less than 6 char - weak password exception catch
                    if (task.getException() instanceof FirebaseAuthWeakPasswordException) {
                        Toast.makeText(getApplicationContext(), "Weak Password", Toast.LENGTH_SHORT).show();
                    }
                }




        });

如果有任何改变，请告诉我。

Firebase createUser.addOnCompleteListener未输入onCreate方法
