Login in android app

I’m trying to login in android app to contribution, but i don’t know what’s is username and password of developer account?

If you mean Github you have to make your own account.

No,i could fork nextcloud android app and clone so run it, but i can’t pass the login activity.
I think in the setup.xml file has somethings to solve it but i don’t know how can i use it ?
