import com.google.android.gms.auth.api.signin.internal.Storage;......error: cannot find symbol class Storage.

I have been facing this problem for sometime and i don't know how to go about it. it started after adding google maps api key to my app project.

This is what i see in Home.java..... import com.google.android.gms.auth.api.signin.internal.Storage;

and the message is.... error: cannot find symbol class Storage.

I'll be very grateful if anyone could help. Thanks
