android - update - Autenticación con Firebase antiguo y nuevo

update firebase user android

Question

Tengo un problema que no puedo conectar con más de un proveedor de Internet con mi aplicación. Primero creí que era la nueva versión de Firebase, pero parece ser otra cosa.

Si instalo un nuevo emulador dentro de Android Studio y me conecto a cualquier conexión de internet, solo me permitirá usar esa conexión para ingresar a mi aplicación.

Cuando creo un nuevo proyecto y lo pruebo, el problema sigue ahí.

siguiendo dentro loginActivity no se llama.

firebaseRef.authWithPassword()

Me da el siguiente diálogo

La actividad o las credenciales de autenticación pendientes fueron suprimidas por otra llamada a auth

Y esto salió ahora

Hubo una excepción al conectar con el servidor de autenticación: no se puede resolver hos "auth.firebase.com": ninguna dirección asociada con el nombre de host

SDK Tools - Servicio Google Play (versión 30)

Herramientas de SDK - Repositorio de Google (versión 26)
