问题
I want to build an Android app that uses firebase authentication google sign in. But want to use a custom database(eg MySQL) which will store some video files.
I want to keep a track of the videos that my users will be watching.
Can i connect the firebase to my custom database so that it can hold data of the user's behaviors.

If you're asking if you can use Firebase Authentication, but use your own database, that's fine. You have the option of picking and choosing which parts of Firebase meet your needs. You need not commit to any part of Firebase that does not.
If you're asking if Firebase (both Realtime Database and Firestore) can act as a proxy for other databases, that's not possible.
