DataBase is empty I guess or removed

[adetheprince]

I am trying to test your App, but I guess the data file are removed from your fire base.
I have tried your App on Play Store and it has some questions but when I test this using your Json data (google-services) there is no Questions or any Category table I also wanted to try with my own fire base that I've created buy I still get empty data, (no any table about category or answers or any )
Does this come with sql file that is not included in the package or am I doing something wrong?
I am new to android and I am trying to learn from your code, is it possible you can share the data file as demo or test?
Many Thanks.
