Firebase - Why it does not execute addOnCompleteListener code

Question

How does addOnCompleteListener work, it is not a System that will be called when the signInWithEmailAndPassowrd operation is executed? It enters a correct login and password and click on the button it reaches the task.addOnCompleteListener but does not enter the onComplete method.

Task<AuthResult> task = mFirebaseAuth.signInWithEmailAndPassword(user.getEmail(), user.getPassword());



                task.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        Task<AuthResult> taskUser = task;
                        Log.i("app", "Sucesso - " + taskUser.isSuccessful());
                        if (taskUser.isSuccessful()) {
                            booSucessLogin = true;
                            mFirebaseInteractionLogin.sucessSiginUp(user);
                        }else{
                            booSucessLogin = false;
                            Log.i("app", "Falha - " + taskUser.getException().toString());

                            mFirebaseInteractionLogin.errorSiginUp("The email address is badly formatted", taskUser.getException());
                        }

                    }
                });

Weird, I tested it on another device and it worked.

I’ve seen some reports of the same problem and it may also be the implementation 'com.google.android.gms:play-services-auth:X.x.x outdated in the project.

Or it could be google play outdated in the app!!!
