Can you tell me please, how can I implement/Use Facebook, Twitter and Gmail login?

This is supported by the Firebase UI module. Use something like:

FirebaseUIModule.builder()
        .setProviders(EmailAuthProvider.PROVIDER_ID, PhoneAuthProvider.PROVIDER_ID)
        .build()

Then follow Firebase docs for setup and configuration.
