Thanks for providing this sample. I've cloned the project and got this working on several devices. My goal is to use the SignIn on the Android TV platform. Unfortunatly when running this on a Android TV emulator I get the following exceptions in my logcat:
com.google.android.gms.internal.auth-api.zbaz could not execute call because it requires feature (auth_api_credentials_begin_sign_in, 7).
Missing Feature{name=auth_api_credentials_begin_sign_in, version=7}
Does Firebase not support Android TV or is there something wrong in my emulator setup?
Regards,
Peter
