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

GoogleSignIn / GoogleSignInClient were introduced in Google Play services SDK version 11.6.

Older versions have slightly different class names and require a GoogleApiClient.

Please upgrade to 11.6 from Android Studio and configure below dependency.

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