Updated all my sdks to the newest version and checked the .aar files ( all are the same version ) . What the hell im doing wrong ? I also used the Google Play Service Setup multiple times that didnt helped either... I heard some people talking about a plugins/android/googleplayservice_lib folder, but theres no im my project. All the .aar files are in the /plugins/android dictionary. I really hope that someone can help me.... how hard can it be to install play services ?
