Open FirebaseUI Auth sign in screen if user is not logged in.

Set Providers is deprecated. Use setAvailableProviders

So the else statement would contains this block-
List<AuthUI.IdpConfig> providers = Arrays.asList(
new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.PHONE_VERIFICATION_PROVIDER).build()
);

                startActivityForResult(
                        AuthUI.getInstance()
                                .createSignInIntentBuilder()
                                .setIsSmartLockEnabled(false)
                                .setAvailableProviders(providers)
                                .build(),
                        RC_SIGN_IN);

Need to use this code now:

                    final List<AuthUI.IdpConfig> providers = Arrays.asList(
                            new AuthUI.IdpConfig.EmailBuilder().build(),
                            new AuthUI.IdpConfig.GoogleBuilder().build()
                    );
                    startActivityForResult(
                            AuthUI.getInstance()
                                    .createSignInIntentBuilder()
                                    .setIsSmartLockEnabled(false)
                                    .setAvailableProviders(providers)
                                    .build(),
                            RC_SIGN_IN);
