Answer 1

I encountered this problem after adding google-play-services, but it was on a project that was not using the sdk for AdMob. After doing a clean rebuild, I stopped receiving this error. So if you are experiencing this, but are not using AdMob or still cannot figure it out for whatever reason, try doing a project clean rebuild. That is what worked for me.
