Firebase does not work with multiple apps

Question

all right?

I started a project in Firebase and Linkei two related applications in the same project.

I made an equal login/signin system for both. It turns out that for an app, Sign in works normal but for the second app, when I click register the app never completes the response. The method for Sign in is equal in both:

 public void bntRegistrarRClick(View v)
    {
        (firebaseAuth.createUserWithEmailAndPassword(txtEmail.getText().toString(), txtSenha.getText().toString())).
                addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if(task.isSuccessful())
                        {
                            Toast.makeText(RegistroActivity.this, "Registrado com Sucesso", Toast.LENGTH_LONG).show();
                            Intent i = new Intent(RegistroActivity.this, CreateProfileActivity.class);
                            startActivity(i);
                        }
                        else
                        {
                            Log.e("ERROR", task.getException().toString());
                            Toast.makeText(RegistroActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
                        }
                    }
                });

    }

Does anyone have any idea what the problem is?

Answer 1

I appreciate the comment, maybe I didn’t explain myself very well! What I wanted was for two apps to connect at the same bank which I was unable to do.

The problem was that I had put the apps in different projects of Android Studio and in fact they should be in the same project with different modules.

Go to the firebase panel -> Authentication ->Login methods -> Multiple accounts per email address is to enable the option so the same email can log in several times. Follow in the user area to see the result.
