Cannot resolve GoogleSignIn and GoogleSignInClient

Question

I am not able to use GoogleSignIn(com.google.android.gms.auth.api.signin.GoogleSignIn ) and GoogleSignInClient(com.google.android.gms.auth.api.signin.GoogleSign

Answer 1

I was having the same issue

GoogleSignIn and GoogleSignInClient were introduced in version Google Play services SDK version 11.6. In older versions GoogleApiClient was used.

So try changing the compile 'com.google.android.gms:play-services-auth:11.4.2' to 'com.google.android.gms:play-services-auth:12.0.1' in dependencies

dependencies { compile 'com.google.android.gms:play-services-auth:12.0.1' }
