Class GoogleSignIn not found in auth library

Question

I have got problem with signing to Google play by android app, i added: compile \'com.google.firebase:firebase-auth:11.4.2\' and compile \'com.google.android.gms:play-services-a

Answer 1

Here is the release note for version 11.6.0

In Auth Library :

Added the GoogleSignInClient and GoogleSignIn classes. GoogleSignInClient provides the entry point for interacting with the Google Sign In API.

so inject 11.6.0 version of auth artifact.

compile 'com.google.android.gms:play-services-auth:11.6.0'

compile now deprecated so it's better to use implementation

implementation 'com.google.android.gms:play-services-auth:11.6.0'
