Okay so I recently got went and got Google Game Services from GitHub. It was all working fine till I then went and got Google Anayltics for Unity from the Google Developer website.
I searched around and found that the google-play-services.jar (I think it was called that) was causing a problem and wouldn’t build. Some kind of Dex error. So I deleted that file that was causing a problem. Now, unfortunately, Google Play Services no longer works which is understandable. Any idea on how I can get both Google Play Services and Google Anayltics to work together?
These are the two errors that come up, I’ve just repeated the problem to show what error comes up:
I was this same problem.
There’s a open issue Conflict with play-games-plugin-for-unity · Issue #51 · googleanalytics/google-analytics-plugin-for-unity · GitHub
They wouldn’t recommend deleting the classes from the .jar. Also, in the meantime you can use Google Play Services r23 and it works.
You can download r23 here: http://dl.google.com/android/repository/google_play_services_7095000_r23.zip
Use Google Play Services r23 fixed the problem for me.
This might be late to replay to this post but it will help to others who is facing same issue so i though to post here
