问题 I'm using Firebase's new framework and I'm attempting to monitor the login state of the user on both the Login and Signup VC's separately.

问题 I added facebook login with firebase authentication on my application, but the login authentication works only from the Android API 24. When I try to use a lower level API the screen freezes and the application stops working. It is too high, most of the users have a lower API level.

问题 I am using Firebase Database, and Firebase Authentication, allowing user to sign in with Email/password or Google Sign-in. In the login activity I am trying to check if the user signing in with Google, is doing it for the first time or no.
