firebase - 'com.google.android.gms.common.api.GoogleApiClient' is deprecated

Question

I'm using in my app Google sign-in method and I have updated today my dependencies to:

implementation "com.google.firebase:firebase-core:17.1.0"
implementation "com.google.firebase:firebase-auth:19.0.0"

And I stared to get warnings about deprecated classes.

Warning:(26, 12) 'com.google.android.gms.common.api.GoogleApiClient' is deprecated

And

Warning:(27, 36) 'com.google.android.gms.common.api.GoogleApiClient.Builder' is deprecated

This is my code:

static GoogleApiClient provideGoogleApiClient(Application app) { //deprecated
    return new GoogleApiClient.Builder(app) //deprecated
            .addApi(Auth.GOOGLE_SIGN_IN_API).build();
}

My app is still working but how can I get rid of this warnings without the need to downgrade the versions?
