Answer 1

I found a solution, I have a application class that Creates a Retrofit and then i just created a ResponseBody and converted using responseBodyConverter(,)

                @Override
                public void onError(Throwable e) {
                    if (e instanceof HttpException) {
                        ResponseBody body = ((HttpException) e).response().errorBody();

                        Converter errorConverter =
                            application.getRetrofit().responseBodyConverter(Error.class, new Annotation[0]);
                    // Convert the error body into our Error type.
                        try {
                            Error error = errorConverter.convert(body);
                            Log.i("","ERROR: " + error.message);
                            mLoginView.errorText(error.message);
                        } catch (IOException e1) {
                        e1.printStackTrace();
                        }
                     }



                static class Error{
                String message;
                }

the JSon received was {"error":4041,"message":"Email not found"} thas why the class Error, i just created a variable message because i just want need to show the message to the user
